Is collagen a peptide?

Hydrolyzed collagen supplements are technically a mixture of short peptide fragments, broken down from the collagen protein so they absorb better when taken by mouth, which sets them apart from the injectable research peptides on this site. Collagen peptides have their own human trial record for skin and joint outcomes, summarized on this site's collagen peptides profile, separate from the melanocortin and growth hormone peptides most people mean when they ask about research peptides.
