🧪 Formulation Notes

Performance-enhancing BCAAs & electrolytes Ensure you’re maximizing muscle recovery and peak performance with the addition of BCAAs to your regimen. Designed with the competitive athlete in mind, MuscleTech researchers have created a superior BCAA formula. Amino Build is a scientifically dosed muscle-and performance-enhancing formula designed to supply your body with the critical BCAAs you need to boost your strength and support recovery.

This advanced formula can be taken before, during or after training, and it will help build more muscle than regular amino formulas.

Build 3.75 lbs. of lean muscle in 6 weeks Amino Build contains a scientifically validated dose of betaine to support muscle endurance and lean muscle.

In fact, in a clinical study, subjects using the exact dose of betaine built 3.75 lbs. of lean muscle in 6 weeks compared to 0.66 lbs. by the placebo group.

More muscle, more power and better results are yours. Boost strength by 40%

Amino Build has the same 4 g dose of leucine shown in a research study (conducted at a leading international university) to help subjects increase their 5-rep max strength by 40%!

Boost endurance performance from the first dose

The 1 g dose of taurine found in a full serving of Amino Build has been shown by research on trained athletes to enhance endurance performance.

Give your muscles the fuel they need to perform with Amino Build. Replenish electrolytes

Amino Build delivers coconut water and watermelon juice, plus essential electrolytes to help replace what is lost during exercise.
