Whey protein supplementation led to a greater increase in biceps brachii muscle thickness (10.1 ± 3.8%) compared to leucine-matched collagen peptides (6.0 ± 3.2%) after a 10-week resistance training program.
Whey protein may be more effective than collagen peptides for increasing biceps muscle size in untrained individuals.
