This article is educational and does not replace medical advice. Prescription medication requires review by a licensed clinician and, when appropriate, a valid prescription. Compounded medications are not FDA-approved, and the FDA does not verify their safety, effectiveness or quality before marketing. Treatment eligibility is an individual clinical decision.

Peptide therapy: evidence and safety

Peptide therapy is marketed aggressively and regulated inconsistently. This hub separates approved uses from research compounds, human evidence from animal data, and legitimate clinical care from research-chemical sales.

Quick answer

Peptides are short chains of amino acids. A few are FDA-approved drugs for specific indications; most sold for anti-aging, recovery or physique are unapproved, sold as 'research chemicals,' and supported mainly by animal data. We grade the evidence honestly and never link to research-chemical sellers.

How the dates on this page work. Manufacturer self-pay prices — NovoCare and LillyDirect — were re-read on the manufacturers’ own published price guides on 4 August 2026. Figures captured from third-party provider websites carry the date we read that provider’s page, which may be earlier; where it is, the row says so. We do not restamp a figure we have not re-read.
