Loved by our Athletes

Blue Star Nutraceuticals nailed it with this BCAA formula. If you want a legit intra-workout drink packed with ingredients your body actually uses, this is it. I’m all about the Orange Drink flavor—it keeps me fueled through big training sessions and makes sure the aminos are flowing.

Steve Nesrallah

These are a staple for me during training. I sip on them during my workouts and they help me stay hydrated, push through longer sessions, and feel less drained by the end. The flavors are fun, and it’s honestly something I look forward to drinking mid-workout (which says a lot).

Christina Hardway

You’ll always catch me sipping on AminoFast during my workouts. It’s that good and it works that well.

James Johnson

This is my ideal intra-workout drink. The flavors are spot on—exactly what they say on the label—and they make staying hydrated enjoyable. It helps me push through my workouts without crashing, keeping me energized and feeling great from start to finish.

  • Stay Hydrated and Cramp-Free Electrolytes and coconut water help keep your muscles firing and fluid balance in check.*

49% Less Soreness†

† 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).* 

75% Increase Time to Exhaustion†

† 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)

How AminoFast™ Works

When you train, your body breaks down muscle, depletes energy, and burns fat—if it’s given the chance. AminoFast™ supports all three systems at once, giving you the advantage from the first rep to the final sprint.*
  • 01 Fuel Muscle with BCAAs BCAAs help reduce muscle protein breakdown during training, helping preserve lean mass and improve recovery.*
  • 02 Transport and Deliver with Glutamine Glutamine enhances BCAA uptake into the muscle, making every gram count.*
  • 03 Burn Fat with Carnitine and Taurine These key aminos improve fatty acid transport and oxidation—turning fat into fuel.*
  • 04 Increase Thermogenesis with Kinetiq® Kinetiq® has been shown to help activate beta-3 receptors to increase fat burning during steady-state and resistance training.*
  • 05 Stay Hydrated with Electrolytes Coconut water and sea salt help keep muscles hydrated, nerves firing, and performance high.*

Great Boost During Lifting

Because of my schedule I usually lift at night between 6 and 7pm. Using Aminofast gives me the energy I need to make my workout intense and fast paced. Also, the Gummy Bear flavor is great!

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.
