What is a peptide?
A short chain of amino acids. Smaller than a protein, larger than a single amino acid.
A peptide is a short chain of amino acids. It sits between two other things you may have heard of: it is larger than a single amino acid but smaller than a full protein.
Amino acids are the building blocks, and when a handful link together, that short chain is a peptide. The category covers a wide range, from research compounds to GLP-1 medications.
TRKD+ uses 'peptide' the way the community does and helps you keep track of the ones you care about. It does not advise on any specific peptide, which is a matter for a licensed provider.
