The amino acid

One of the best supplements at iHerb offered in my opinion, after using the pure Leucine, had a better performance in training, an improvement in protein synthesis and muscle recovery. Recommend

Pretty nice, i've been trying the LeanGains diet and using this Leucine and the MRM BCAA I achieved nice gains. The taste is not good but it's worthwhile.
