Branched-chain amino acids and a complete protein source are different formulations. Existing dietary protein intake changes the practical question.
Separate studies, not a head-to-head trial. Source-checked conclusions do not validate older numerical estimates.
Source-checked conclusion: uncertain
Muscle and performance benefits have not been consistently demonstrated.
Complete dietary protein matters.
Population: Adults in exercise studies. Formulation: Branched-chain amino acids.

Source-checked conclusion: supported
Whey supplies complete protein for muscle repair and training adaptation. It helps meet protein needs; extra powder is not necessarily useful when intake is already sufficient.
This supports meeting protein needs, not superiority over an adequate food-based diet or a guaranteed strength increase.
Population: Adults exercising with adequate energy intake. Formulation: Whey as a dietary source of complete protein.
