Lose Sweat. Not Performance.

You're Losing More
Than You Think

Sweating off as little as 3% of your body’s water can completely sabotage your physical and mental performance. And unfortunately you’re losing a lot more than just valuable water in the process. Intense exercise also robs your body of precious electrolytes.


The problem with energy, like most things, is that you don’t know what you’ve got till it’s gone. And by that time it’s way too late.

With AminoFast™ in your system you can be certain that your body is ready to perform at 100%, whatever the task.



Electrolytes are like engine oil for you body. They can’t make you start, but they absolutely keep you going. Every serving of AminoFast™ has electrolytes in abundance and that’s why the next time you hit your usual mid-lift, mid-workout, or mid-day wall you won’t even know it.


The three Series of AminoFast™ are specifically designed to work in combination with one another. Their unique formulas complement not only your relevant needs but also their individual benefits. All three products can, and should, be used together, as needed. You now have the strength, stamina, and energy to really reach your wildest goals. Get out there, and finish what you started.


Getting the right kind, and the right amount, of energy can be exhausting enough in itself. When performance matters, the last thing you should be worrying about are nervous jitters, sugar highs, or caffeine crashes.

Discover the Science of Aminofast™

Our fully transparent white papers detail how we go from molecular mechanism to clinical outcome, challenging each individual ingredient at every stage with painstaking detail. However, if that's not for you - we've laid out the clinical research on the key ingredient in Aminofast™.


Graph #1: In a randomized crossover study with 7 male elite endurance athletes, time to exhaustion was measured during a 90% VO2 max test following 3 minutes of 75% VO2 max training. A key ingredient in AminoFast™ produced a 63% increase in time to exhaustion compared to water alone, and a 75% increase in time to exhaustion compared to a glucose-based sports drink (p < 0.05) Graph #2: 30 young healthy female and male adults volunteered for a double-blind, placebo controlled, crossover design study. Participants performed a 140 squat exercise protocol to induce delayed-onset muscle soreness (DOMS) while consuming key ingredients in AminoFast™ or an isocaloric placebo. Muscle soreness was determined using a visual analog scale (VAS). Peak DOMS occurred in the placebo group at 48 hours, the time point when a key ingredient in AminoFast™ was associated with a 49% reduction ( p < 0.05).* 



L-Glutamine improves BCAA delivery to your working muscles. Performance-wise, this means less muscle breakdown, and better recovery. But it also means your old sports drink (which is very likely missing L-Glutamine) is no longer wasting your time, energy, and money.

BCAA Matrix

AminoFast™ has a massive 6-gram serving of free-form BCAAs (leucine, valine, and iso-leucine) in a clinically validated 2:1:1 ratio.* This ratio has been shown to stimulate muscle building and prevent muscle breakdown during exercise. So if your goal is to build muscle, maintain energy during your workout, and eliminate searing soreness after training, AminoFast’s BCAA Matrix is essential.*


Electrolytes are like the motor oil in your car: they don’t make it start, but they’re sure to keep it going. In order to function properly, your digestive, nervous, cardiac, and muscular systems need ample amounts of electrolytes. But when you sweat you lose them, and they’re not easy to get back. That’s why every serving of AminoFast™ has electrolytes in abundance. Next time you hit the mid-workout wall, throw back a serving of AminoFast™ and you’ll be ready to go without missing a set.

Won't go to the Gym without it!

AminoFast is like having a workout partner in the gym pushing you through your workouts when you feel like your spent. "one more, one more!" Love this stuff.

David C.
Amino Fast

The gummy flavor is a little sweet for me. All thought it does taste good. Haven't been as sore since I've been taking it.

Luis P.I. (Fresno, US)
A must have!

Ever since taking this product I’ve seen a noticeable change in my energy level during my workout. Getting the benefit of the electrolytes and aminos in one package has been great!

Pat G. (St Louis, US)
Amazing product!

Finally a product that lives up to its claims.
Last Saturday, I did 3 workouts including a 6 mile ruck. The next day my body felt like I was beaten by a bag of doorknobs. I drank a serving of Aminofast and very shortly thereafter I began to feel good to go. I’m a believer and will restock shortly.

J.P. (Denver, US)
This is delicious

I am a bit weird and I don't like the taste of water, so adding this to it is amazing and packed full of ammonia great for me. Highly recommend

Tony T. (High Point, US)
Great product

Really helps while working out and helps keep the soreness down.

Dylan W. (Santa Clara, US)
Game Changer

I’ve always used various supplement stacks but never really considered BCAAs. But after finally picking up a tub of this stuff, I’m never going back to training without it. Drinking a serving of this during/post workout, I’m left with virtually zero soreness or fatigue the next day. Drinking this stuff is leaving me less sore and feeling better in my 30s than when I was training in my 20s. Highly recommend.

Jim H. (Corona, US)
This stuff is Awesome
