# Peptide Index

> Legal status, evidence, and legitimate ways to get it. No dosing. No vendors.

What this site refuses to publish: We give no dose for a compound that is not FDA-approved. For an approved drug, we sum up the official label and cite it. We name, rank or rate no seller, clinic, pharmacy or marketplace, and we point to none. We print no price for any product. Details: https://peptideindex.ai/methodology#refusals

Information, not medical advice. Every record says when each fact was approved and which source it rests on.
