Effects of Whey, Caseinate, or Milk Protein Ingestion on Muscle Protein Synthesis after Exercise
This study compares different types of milk protein to see which one helps build muscle best after exercise, finding that whey protein works quickly and effectively.
Effects of whey protein hydrolysate ingestion on post-exercise muscle protein synthesis compared with intact whey protein in rats
This study shows that whey protein helps build muscle after exercise, and a special type of whey protein called hydrolysate works even better.

The study found that whey protein helps build muscle better than collagen, but it didn’t test steak or whether collagen helps tendons and ligaments—so only part of the claim is backed up.
The Effect of Leucine-Enriched β-Lactoglobulin Versus an Isonitrogenous Whey Protein Isolate on Skeletal Muscle Protein Anabolism in Young Healthy Males
This study compares two types of protein to see which one helps build muscle, finding that they might be similar.
