Branched-chain amino acid that directly stimulates mTORC1 signaling and helps trigger muscle protein synthesis when protein meals are under-dosed.
Oral ATP supplement that increases extracellular ATP levels, improving blood flow via purinergic receptor activation on endothelial cells. Enhances muscular excitability, recovery, and lean body mass. Does not significantly raise intracellular ATP (that's produced endogenously).
