That means you get a boost in short to medium duration high-intensity muscle performance. Think bodybuilding-style training, CrossFit, and HIIT.*Beta-alanine has been shown to increase muscle power output, strength, training volume, exercise performance and peak oxygen uptake (aerobic capacity) when used consistently.*Acetyl-L-TyrosineAcetyl-L-tyrosine is a more bioavailable form of the amino acid L-tyrosine, which is used by the brain to make dopamine.
