C4 50X

MADE FOR THE XTREME*

The extreme among us believe in all or nothing, go big or go home. For the extreme, average is not enough. There will always be a boundary to break, a limit to push, a goal to demolish, and more to achieve.

After extensive research we developed C4 50X, a pre-workout supplement made for your extreme passion, drive and commitment to your workouts.

LEVEL UP WITH C4 50X*

For years you’ve relied on C4 to help you raise the bar and push limits. C4 50X is the next step for those who want to level up. Its formula features approximately 50% more of the active ingredients per scoop that were key to the power of the original C4 Extreme®. C4 50X also has two new ingredients: TeaCor for hard hitting energy; and XCELICOR™ to help the energy last longer.*

BURSTING WITH FLAVOR

C4 50X is available in our classic Fruit Punch, Watermelon and Icy Blue Razz flavors. 

How should I take the C4 50X?

Take one serving, mixed with 4-6 oz of water, 20 - 30 minutes prior to training.

How many servings of 50x can I take in a day?

Given the fact that the C4 50x features 50% more active ingredients per scoop, many people have had success with one 1 serving per workout. Once you have assessed your tolerance with one serving, you may take an additional serving prior to training.

I am currently taking a PDE-5 medication for ED, why is there a warning on the label not to take this?

Because of the nitrates ability to relax the walls of the blood vessels to promote increased blood flow, nitrates are frequently included in men’s sexual health products. Taking nitrate ingredients and PDE-5 inhibitors at a similar time could cause an unsafe drop in blood pressure. Because some dietary ingredients also act as PDE inhibitors, please consult a licensed qualified health care professional before taking this product with any dietary supplement, product, or medication.

How much caffeine is in on serving of the C4 50x?

The C4 50x contains 200mg of caffeine per serving.

What is there 50% more of in the 50x?

The ingredients: Beta Alanine, Creatine Nitrate, Arginine Nitrate, and the Explosive Energy Blend are all formulated with 50% in the 50x over the flagship C4.

So you’re saying the C4 50x is just a scoop and half of the flagship C4?

No. In addition to having 50% more stimulatory ingredients, the C4 50x is formulated with the ingredient XCELICOR. XCELICOR is an innovative patent protected caffeine ingredient which combines caffeine and pterostilbene to slow the absorption and significantly extend the half-life of caffeine by up to 25%.

Why does my skin have an itchy/tingling feeling after taking the C4 50x?

The C4 family of products are formulated with the amino acid Beta Alanine, which supports muscular endurance, and often has a tingling/itching effect experienced by users about 10-20 minutes after consuming the product.

Can I stack other Cellucor products with C4 50x?

You certainly can, however you want to make sure to not take in an excess of nitrate ingredients, nor stack stimulant based products such as preworkout and weightloss products. One stimulant based product to be used at a time (C4 Family of products, SuperHD, D4 Thermal Shock) Product with higher concentration of nitrate based ingredients such as the C4 family, NO3, and CN3 are recommended to not be used together.

Excellent Energy and Focus review by Crimson28

A quick intro before the actual review - I am a collegiate student-athlete and I am always on the lookout for anything that might help me create an advantage for me in practice, games, and lifts. I’m careful about my supplements, and have my standbys: whey protein powder, creatine monohydrate, fish oil, multivitamin, and a greens product. Finding a preworkout that is NCAA safe, effective, and palatable is no easy task, but I believe that in C450x, Cellucor has created a product that rivals any other preworkout in all three of these categories. Mixability: The recommended dose calls for 1 scoop in 4-6 oz. of cold water, but I typically double the water when taking preworkout. I find that this allows me to slug back enough 20-30 mins before the workout to get me locked in, but also have some to sip on during my warmup and first few sets. On this particular day, I went with 10 oz. of cold water along with a few ice cubes. The scoop of powder melted easily into the water, even with the ice cubes, and just a quick shake got all the powder fully dissolved. There were no floating particles whatsoever, making for an extremely smooth feel when sipping (or chugging!). Taste: Fruit Punch This stuff tastes great. Seriously unreal. It goes down like juice and gets you jacked up to lift heavy stuff. Think the Hawaiian Punch we all grew up with, if it made you want to take a bite out of a 45lb. plate. For me, 10oz. of cold water is the sweet spot for most preworkouts, but I tend to err on the side of watered-down as opposed to heavily concentrated. Even with the extra water, C450x Fruit Punch had an incredible taste, sweet and fruity without tasting at all like a powder. Out of all the Fruit Punch-flavored preworkouts I’ve tried (most in 10-12oz. of water), C450x is by far the smoothest, best tasting of the lot. I found myself sipping for the flavor rather than chugging for the effects. Dosing: I find that preworkout kicks the hardest for me when I take it 20-30 minutes before my workout after having eaten a medium-sized, balanced meal roughly an hour prior to that. Using this timeline for my first dose of C450x, I experienced a solid boost of energy about 10 minutes into my warmup sets. It wasn’t a jittery, antsy sort of energy - I felt calm and focused before each set. There was no crash, which was exceptional for such a long-lasting dose, but what stood out to me was the laser-focus I had during my workout. This might have been in part due to my stretching the dose over a greater volume of water and drinking time, but I felt a clean energy throughout my workout and had the focus to harness it. I wanted to see how I’d respond to the recommended dose in the recommended 4-6oz. of water. I took it 35 mins prior to my workout, an hour after eating. It definitely hit me faster, and I experienced largely the same clean energy and focus. I was not a fan of the taste in this case. The Fruit Punch flavor was almost overpowering. It lost its Hawaiian Punch taste and although still sweet and tropical, I found myself just wanting to get it down rather than savoring it. Lastly, I decided to try a dose of C450x on an empty stomach, just to see how the caffeine mixture would play. I went back to doubling the water for this trial and again found the “sweet spot” for great taste and great results. It kicked in about 20 minutes after finishing the drink, and I felt the same great energy and focus for the majority of my workout. Towards the end, however, when i started to fatigue, I experienced some stomach discomfort. I didn’t cramp up, but it was certainly not the kind of feeling you want to have throughout a tough lift. My recommendation is to start dosing with around double the recommended water, and then work your way down to what you feel is a good combination of water and flavor. This will depend largely on what you like. i would also recommend having something in your stomach before you slug back C450x, or any preworkout for that matter. It doesn’t have to be a whole meal, just something that’ll keep your shake from sloshing around. Formula: I’m not a coffee or tea drinker, so any caffeine I ingest comes from preworkout, which I take occasionally. I usually sip aminos before and during my workouts, so while I’ve tried a fair number of preworkouts, my caffeine tolerance is relatively low. C450x packs 200mg of caffeine per serving which is plenty for me. I felt a good, solid energy and clean focus so no complaints there. I’m happy to see calcium, and Vitamins C and B12 in the formula, although I’m not sold on the Creatine Nitrate. I’ve always taken Creatine Monohydrate and had great results with it. This is more just personal preference, although if I’m really jonesing for some monohydrate, there’s only 1.5g of Nitrate in C450x so I’ve got plenty of room for more if I want it. All in all, C450x packs a good deal of oomph into a solid formula with a much shorter ingredient list than many of its counterparts which is something I like to see. It’s also free of banned substances which is a plus because I like my eligibility. Alot. Recovery / Energy: After my workout I remained energized through the afternoon and evening. I wasn’t bouncing off the walls, but I did feel pretty good about being able to sit down and focus on reading and work. This is a huge boon for student-athletes. Pounding a protein shake and a RedBull after a workout so you can go spend another few hours in the library without collapsing is never ideal. I wasn’t jacked up like I’d been during my workout, but that sharp focus tapered off very slowly which makes C450x perfect for a late afternoon workout. The day after my workout, I woke up feeling rested even after only 6 hours of sleep. My recovery might have been enhanced a bit, but I didn’t notice anything spectacular, and nor did I expect to. I didn’t feel much of a pump while on C450x, but I wasn’t really looking for one either. Rather than a skin-tearing pump, C450x provided clean energy and good focus which are the two things I look for first in a preworkout. All in all, C450x packs a pretty good punch. If you’re looking for a skin-tearing pump or a preworkout to add 100lbs to your bench, this isn’t it, and nor does it claim to be. Don’t hulk smash your shaker bottle if you don’t look 20lbs heavier with veins popping out of your eyeballs while on C450x. This is a silky-smooth energy intensifier. It’ll put you right where you need to be to get the most out of your workout without walking around the gym yelling at the weights. C450x does a couple things, and does them exceedingly well. If you want something that tastes great, goes down smooth, locks you in, and keeps you there for a while, this is your new preworkout.

Powerful pre-workout for intense workouts review by Joshy J

After trying C4 several times and finding that it did not work well for me, I wanted to give C4 50x a fair chance...I'm very glad that I did. This pre-workout lasted throughout my lift and I felt great, no upset stomach that some people get from taking a strong pre. I used the standard amount of water that the label suggests and tried (on two separate days) one and two scoops. I liked keeping the amount of water low so my stomach wouldn't feel full from the C4 50x, but because it wasn't very diluted, the flavor was a little strong and sour. Not too sour that I did not enjoy it, but that just comes from using a small amount of water. C4 is the only pre that I enjoy the Blue Razz flavor more than any other; I usually go for fruit punch pre's, but this is my one exception. I preferred taking two scoops, and took it about 20 minutes before the workout on a fairly empty stomach. It turns out that it took closer to 30 minutes to kick in, but I love getting that amped feeling after my first set! While I was lifting, I felt a nice heat from my core pulsing throughout my muscles which gave me a great pump and consistent energy for the whole workout. It's so rare to find a pre that lasts the whole lift. The energy blend is perfect for the caffeine, I had no jitters, but I personally also love the tingles which were not amazing from C4 50x. I am a beta-alanine fiend! However, this was the cleanest feeling energy boost I had had during a workout in a while. Well done, Cellucor! I'lll be buying this product again for sure.

I was excited to try out C4 50X for the first time. C4 Extreme has been at the top of the preworkout market for years and this is their best version of it to date. I never had to exceed 1 serving which provided steady energy throughout my entire training sessions. (2-3hrs) I varied the amount of water from 8oz to 20oz. If you have tried C4 before you know their flavors are on point and C4 50X is no different. I always took my 50X on a “full” stomach. I preferred to mix with at least 16oz of water so that I could drink it starting about 30 minutes preworkout and sip on it during the trip to the gym. Whether mixed with 8oz or 20, the flavor still rocked and it mixed perfectly. If you prefer to dry scoop your preworkout this is one of the better products to do so! No bioperine which leaves a burning sensation and it tastes just about the same as a pixie stick. I only dry scooped when I forgot to mix before the gym so the dosing was ~ 5 minutes preworkout. It didn’t kick in for about 15 minutes but that was fine as it took about that long to warm up. The beta alanine (BA) dosing is on point and anyone on a high volume routine will definitely notice a difference in their endurance. The dosing is more than enough to give the BA tingles which I personally enjoy. The creatine nitrate (CN) really impressed me. I have always been an advocate of creatine preworkout but the added nitrates really add to the pump effect, which 50X provided very well. The extra CN can definitely be felt as pumps felt fuller and seemed to last most of the workout once accessory lifts began (final 45-60 minutes). Maybe adding some monohydrate or even more CN to cover the daily dose of creatine would be my only change on that. I’ve seen other reviews not excited about the niacin and I would have to agree. It is a highly controversial preworkout ingredient and can be bothersome to some people. I never had any issues but someone with a high stim tolerance who might need 2 scoops could be bothered by the high dose of niacin. With such an awesome dose of BA I don’t see any need in having niacin as it really doesn’t provide much use in a pre. Overall I’m highly satisfied with C4 50X and I believe it is a step in the right direction for Cellucor as higher dosed preworkouts are starting to take over. 3.8/5

Taste: I tried the fruit punch flavor and the taste was solid! I'm normally not a fruit punch kind of guy but it was great. The taste was not too tart or sweet • Mixability: This stuff mixed really well. I personally used about 10oz of water. I didn't noticed any particles or clumps in it. It mixed very easily with a few shakes compared to a lot of pres that need many more • Dosing: I used 1 serving both times I used C4 50x. I took it on an empty stomach both times in the morning directly after waking up, about. I took it about 20-25 minutes before my workout as I normally do. I was zooming when I took it, and I am typically not sensitive to caffeine. I had a solid pump through my workout. • Formula: This new formula is a big step in the right direction. I noticed the beta alanine in it more so than in regular C4 and was given a solid pump right off of my first workout. My focus in the gym was slightly more than I would have on most pre workouts • Recovery / Energy I had solid energy throughout my whole workout with C4 50x. It kept me going when I would usually wear out without a pre or on my intra, although initially I was zooming with energy. I was also able to recover a bit quicker between sets and exercises, probable due to the energy increase. The pump was also solid, it lasted for a while after my workout.

Taste: I tried Fruit Punch and it was pretty tart. At first I tried a serving in the recommended 8 oz. and it was very tart. Next, I tried it with 12 oz. of water and it tasted a bit more sweeter. I would stick with a higher volume of water for next time. I’d rank flavor at about a 8 though; I’ve had a lot worse. • Mixability: This stuff mixes really well, even with the low amount of water. I never noticed any grittiness or particles floating. Just a couple shakes of the shaker and it was good to go. • Dosing: I used 1 serving both times I used C4 50x. First, was about 15 min. before my workout and in a fed state; this was optimal for me, I had great energy the whole time and a great pump. Second, was about 45 min before my workout and in a fed state and this wasn’t as great. The energy didn’t last as long and there wasn’t much of a pump. • Formula: This new formula is a little better than the regular C4. Instead of having to take 3 scoops your first time you can get away with about 1.5 to 2 scoops to really feel the energy and Beta Alanine. I was impressed with how great of a pump I got with it and how good my focus was. I’ve had better, but this is way better than the old C4. I wish there was more Beta Alanine in it because I really like the tingle. • Recovery / Energy I had solid energy throughout my whole workout with C4 50x. It kept me going when I would usually wear out without a pre or on my intra. I was also able to recover a bit quicker between sets and exercises, probable due to the energy increase. The pump was also pretty solid, it lasted for a while after my workout.

This mixes great and I have only used the fruit punch flavor. The flavor is good, of course all preworkouts taste like kool-aid to me. There isn't a funky taste though which makes this easy to drink. The powder mixes really well and leaves no residue. The energy I get from even just 1 scoop (have been using for about 3 weeks now) is great and I take two if I need that extra push in the gym if I'm tired. I've also used a scoop before a 5k race and felt focused and ready instead of my typical questioning myself.

I tried the fruit punch flavor with about 5 oz. the first time, 5 minutes before working out which it ended up being a bit strong taste wise, so I added a little more water to it (not sure how much maybe an ounce or two) The second time I tried the fruit punch, I put in 8 oz. and took it about twenty minutes before. The second time I took it, it was most effective. I would compare the fruit punch in 50x to Mr. Hyde, both are very strong tasting and tasted the same, it all depends what amount of water you add as I found that 6-8oz. works the best, but that's my personal opinion. The great things about this pre-workout compared to a lot of others I've tried is it didn't really bubble up and leave powdery particles like a lot of the leading competitors. Honestly, formula wise, this was the best pre-workout I've ever had. Yes it costs $10 more but the saying is true as always- you get what you put in and if you pay an extra $10 more than other pre-workouts, you won't be disappointed. At first (as usual) I received a little bit of the jitters mainly because I took it and wasn't even at the gym which made me a little itchy but once I got my workout started it was the best pump I've probably ever had, my vascularity was insane and it lasted at least 15-25 minutes post workout (my workout took 1.5 hours). I had amazing amounts of energy after working a 12-hour day then having to play 2 double headers of softball so for this midnight workout, I was definitely impressed with my recovery time as I left maybe 25-30 seconds in between my supersets. Compared to the original 'best' pre Mr. Hyde, which I'm used to taking because it' $10 less, this shatters its pump and effectiveness when working out, my vascularity was through the roof and I had the best pump ever, the only problem and only reason I rated it 4 stars was because it's $40. If cellucor could get this formula to be $35, I'd buy it every time.

I tried the fruit punch flavor and I would say that the product tasted like kool-aid as soon as I tried it. It wasn’t like the older versions where it tasted very weird and not like fruit punch. I would add just an ounce or two a more on the next serving because it tastes a little too sweet with not enough water. It ranks for fruit punch in the top for top 10 because I know a lot of companies use fruit punch as a main flavor but it just doesn’t taste as good. I usually go for blue-razz but fruit punch may be one of my favorite flavors now. I used about 6 ounces of water just like it says to and it did mix very well. Nothing was floating at the top and I would say the mixability is a 10/10. I took this 30 minutes before a workout and then started to feel it as soon as I got to the gym. That’s what I usually do. The second time I took it while I was AT the gym and noticed the amount of pump up I got from taking it while at the gym and I was getting too pumped up for stretching haha. I like the Creatine Nitrate in this product, I definently can tell the amount of vascularity I get from it. The only thing I would change is basically the Niacin, I am very sensitive too it, but it was not as bad. Besides that, I love this product! I did not notice much recovery, I usually take BCAA’s as a form of recovery and think alpha amino x is the best tasting I have EVER had. My energy and pump were out the roof and honestly want to keep using this as my go to pre workout!

Just when I thought I couldn't enjoy anything more than sipping a scoop of C4 before a workout... Smooth Fruit Punch flavor that took a good amount of liquid (~12 oz), and powerful results. The beta-alanine tingle was definitely there, but wasn't overbearing. The energy boost and focus came on steadily, with no crash. I definitely recommend it.

If you like the original C4 this is a great step up if you've built tolerance or just looking for a change. Fruit Punch flavor is pretty good in about 8-10 oz of water. Very similar to ProSupps Hyde. I usually just shotgun pre anyways though. Mixes decent in the recommended amount of water. A few sinkers but blender ball is not needed just give it a few shakes and it'll get the job done. This hits me great taking about an hour after I eat breakfast about 15 minutes before my workout. I absorb pre really fast though. The 2.4 g beta alanine and 1.5 g Creatine Nitrate is the best thing about C4 50x. Not near as much Caffeine as HYDE. Gives me nice endurance through a workout. I would say if your tolerance to caffeine is low but you still want a good stimulant preworkout C4 50x is a good starter. If you have a high tolerance to Caffeine then you'll probably end up two scooping this anyways. But you will definitely get tingly and kill your workout!

I was fortunate enough to sample Cellucor's C4 50x, and I was not disappointed. The pump was great, taste was phenomenal, and I really enjoyed it. Here is my honest review: Taste Flavor: Watermelon Taste in amount of water used: Fantastic! Took it straight to the head, so 1 scoop wit about 2oz of water. Would I change the water amount?: No, I hate drinking a lot before a workout, to the head is the way to go! Can I compare to another market product: No sir. Definitely gave me a pump like no other. I don't normally sweat, but I left my session drenched. Mixability Water used: 2oz Clumps: 1 big clump going in, swished it around about 3 seconds and it was good to go. No blender ball required. Dosing When: 15mins before session Formula What I liked: Caffeine and Creatine What i would change: Couldn't tell you. Way far beyond C4 Extreme, although that one is good too. (Berry Bomb is life) Recovery Nice Pump? Hell yes. Lasted my whole workout. Not very many jitters, but enough jolt to wake me up. Get it people, I promise you won't be disappointed! Thanks again to Cellucor and my man Mitch Yuncker for this opportunity. I appreciate it man! Looking forward to doing it with future products soon.

Now, this is where I was disappointed...I was expecting big things with the inclusion of the TeaCor and Xcelicor, however I'm not a huge 'caffeine only' stimulant guy. If I'm rocking 200mg of caffeine, regardless of what ratio the Xcelicor to anhydrous, I would expect more of an effect but it just wasn't there. Pump and vascularity wise, it was average as that's what creatine nitrate does and with a hefty overkill amount of beta alanine, the endurance was not bad. Overall, I was a bit let down here and feel that including a nootropic or something to compliment the novel stimulants here would have been a potential home run, but ultimately I was left wanting more. A great profile is one thing, but this stuff just didn't do it for me.

Let me start off by saying that I have tried a lot of pre-workout products in the past. All different types of C4, Jack3d, you name it. I didn't know what to expect when I ordered my container of 50x, but I was definitely blown away by the explosiveness, pumps, energy and focus. I take one heaping scoop about 15 minutes before hitting the gym. The flavor is very tasty, especially with cold water. A few minutes later I can already feel my body tingling and ready to crush the weights. You guys really nailed it with the 50x!!! Great job, Cellucor!

The original C4 was a great product, but I grew tolerant and moved away from Cellucor for awhile. Needless to say this pre workout changed my mind completely. The taste was equivalent to how freedom feels. I use very little water with my pre's (4oz maximum) and the fruit punch flavor was not overbearing at all. I think next time I might try more water just to enjoy the taste for longer! As for how it worked? This stuff makes you feel the way seeing Old Glory on the 4th of July feels. I used this on Back/Arms day and it was by far the biggest pump I have ever had. Definite buy in my opinion!

I tried the Fruit Punch flavor. I mixed it with 6 oz. of water and the taste was great! The taste was powerful, but not overbearing like most Fruit Punch flavored pre workouts. I would consider taking C4 50X with 8 oz. of water instead of 6 oz. next time. The mixability was great! A lot of pre workouts have a grainy feel to them, but the C4 50X mixed with absolutely no problems. I took C4 50X 30 minutes prior to my workout about 40 minutes after eating and I felt amazing! The pump was unreal! I also took it upon waking up in a fasted stage. When I took the C4 50X in a fasted stage I had to hit the gym immediately! Pre workout hits a little harder in a fasted stage. 2.4 grams of Beta- Alanine is perfect. I also love the Niacin in the pre workout. I felt the "tingly" sensation, but it wasn't too much. I really did not notice too much of an increase in recovery time when taking C4 50X, but I did have a lot more energy while working out. The pump was great! I felt more "full," even when fasted. I also looked more vascular when taking C4 50X. I had a constant supply of energy throughout my entire workout, which is normally about 90 minutes. The "jitters" went away once I started lifting.

Flavor I Tried: Fruit Punch Taste: I use a minimal amount of water when I take my pre-workout, and this is one of the select few that isnt bitter in only roughly 3-4oz of water, tastes absolutely amazing. Minimal amount of shaking required to completely mix. Personally I wouldn't change the amount of water I use because you don't really need to sip on your pre-workout you wanna get it in you quick so that you can get right into your workout. Comparison Ranking: For a single scoop pre workout, this product has to be in the top 3 for me, taste wise it ranks #1 hands down. Dosing: I sampled this product by taking it 30 minutes prior to my workout, now this may change for everyone depending on how they respond to pre-workout but for me specfically I respond rather quickly, normally having it completely kick in 45-50 mins after taking, which gives me just enough time to get to the gym, stretch, warm up and start killing it. Formula: The formula has a lot of the basics that most do, but for the most part it provides the amounts that you actually want, where some have to much caffine and not enough beta-alanine, this product has the exact amount that you want to get you going and feeling right with 200mg of caffeine and 2.4g of beta-alaline. But what really holds this product over others is cellucors "XCelicor" which provides a longer source of energy and provide a better focus in the gym which when stacked with caffeine really makes you power through your workout. Pump: Im a very vascular person to begin so having my veins show throughout my workout isnt anything I really pay attention to, but when I was taking Cellucor 50x, my veins REALLY popped out, i could trace a vein from my wrist completely up to my shoulders where they disappeared into my chest, which was even commented on by my workout partner. Recovery: Personally my body doesn't really require a lot of down time and recovery time with the amount of BCAA"s, healthy dieting, and fish oils I don't really have much soreness. But I did find that while taking this product I had a lower amount of lactic acid build up in my muscles which allowed to get longer, better sets in. Overall I loved this product, I've always enjoyed Cellucors products having taken almost all of their pre-workouts at this point along with their Whey and SuperHD products. But with this product Cellucor has really outdone themselves and produces an extremely solid and well thought out product. I would recommended this product to anybody looking for a pre-workout thats really looking for a huge edge in the gym.

I love the regular C4 so I had very high expectations for this product. I took it in a fed state about 30 minutes before a super intense workout and my energy levels were insanely high. I felt strong and energized throughout my whole workout, had no crash after and I had minimal soreness despite the intensity of the workout. I can definitely say that it exceeded my expectations. I am one that enjoys the tingles from the beta-alanine and I definitely experienced that with this product! The taste of the fruit punch flavor was good, better than some other fruit punch prewokouts I have tried in the past. It mixed well into my water, I used about 10 oz and there were absolutely no particles of powder that didn't mix. I will be recommending this to all of my customers, especially to those with a high tolerance.

C450x WILL NOT let you down! TASTE + MIXABILITY - I sampled the fruit punch flavor. Mixed well, taste was a little pungent but still much better than lots of other preworkout powders (mixed with 5oz water). I would personally use a little more water next time. As far as fruit punch pre goes, this is pretty great to drink! DOSING + FORMULA - I consumed the C450x 30 minutes before my workout in a fed state. Like clockwork, it hit me as I began my first few sets. It was a perfect mix and focus and energy that powered me through a PR setting bench day (315x3). I felt like it was made up with a perfect amount of beta alinine, B12, and niacin to provide enough energy without going overboard. RECOVERY - My recovery was surprisingly better than usual. After benching my 1 rep max for 3, I went on to slam more weights and complete difficult dropsets and supersets. This resulted in one of the best pumps of my life. All of this with NO JITTERS! Was sore afterwards, but by the next day I was ready to roll. Great recovery.
