Surprising Findings

Collagen increased muscle mass more than placebo despite being low in essential amino acids like leucine.

Leucine is considered the primary trigger for muscle growth. Collagen contains almost none—yet it outperformed placebo in muscle mass gain, defying conventional protein science.

Practical Takeaways

If you're doing hypertrophy training, take 15g of collagen peptides within 60 minutes after your workout to potentially boost muscle mass gains.
