Glossary term

Peptide

Also known as Peptide therapy - Therapeutic peptide

A short chain of amino acids (<50) that signals specific receptors - not all are drugs, not all are safe.

Peptides are short amino-acid chains that function as signaling molecules. Insulin, GLP-1, and sermorelin are peptides - and FDA-approved medications. Others, like BPC-157 or TB-500, are compounded under state rules with limited human data. Research chemicals labeled "not for human use" are not peptide therapy - they're a lawsuit waiting to happen and they skip every safety control real compounding pharmacies run. We prescribe FDA-approved and a small list of compounded peptides where state rules permit, always with baseline labs, COA-verified sourcing, and cycle monitoring. See the peptides explainer before committing.
