Compounded Peptide
A peptide prepared for an individual patient by a licensed compounding pharmacy, prescribed by a clinician and tested for identity, potency and contamination.
Definition
Compounded peptides are prepared by FDA-registered 503A pharmacies from bulk pharmaceutical-grade active ingredients. Each batch is tested by an independent third-party lab for identity, potency, endotoxins and microbial contamination. Compounded is the legitimate prescription pathway in the US — distinct from 'research chemicals' sold without a prescription, which are neither regulated nor safe to self-administer.
