Is collagen a peptide?

Collagen supplements are made of short bits of peptide. The collagen protein is broken down so it is easier to absorb when you swallow it. That sets it apart from the injectable research peptides on this site. Collagen peptides have their own record of studies in people for skin and joints, summed up on this site's collagen peptides profile. That is separate from the growth hormone and melanocortin peptides most people mean when they ask about research peptides.
