Performance-Enhancing BCAAs and Electrolytes
Developed with the competitive athlete in mind, MuscleTech® scientists have created a superior BCAA formula. Amino Build® is a scientifically dosed muscle and performance-enhancing formula, designed to provide your body with the critical BCAAs you need to increase strength and support recovery. This advanced formula can be taken before, during, or after training, and it will help you build more muscle mass than standard amino acid formulas.
Build 1.7kg of Lean Muscle in 6 Weeks
Amino Build® contains a scientifically validated dose of betaine to support muscular endurance and lean muscle mass. In fact, in a clinical study, participants who used the exact dose of betaine built 1.7 kg of lean muscle in 6 weeks, compared to 0.3 kg in the placebo group. More muscle, more power and better results are yours.
Increase Strength by 40%
Amino Build® contains the same 4g dose of leucine as in a research study (conducted at a leading international university) that helped participants increase their 5-rep max strength by 40%!
Increase Endurance Performance From the First Dose
The 1g dose of taurine found in a full serving of Amino Build® has been shown in research on trained athletes to improve endurance performance. Give your muscles the energy they need to perform with Amino Build® .
Replace Electrolytes
The right energy. The right delivery. The right formula. Amino Build® delivers coconut water and watermelon juice, along with essential electrolytes, to replace what's lost during exercise. We've done the research - all that's left to do is train.
