How PSG Vets Every Compound Before It Reaches Your Clinic

When a clinic adds a compound to its formulary, the quality of that compound reflects directly on the practice. At Peptide Source Group, every product in our catalog passes through the same sourcing and verification process before it is ever offered to an approved account.

Manufactured to cGMP standards

Every compound we distribute is manufactured to current Good Manufacturing Practice (cGMP) standards in the United States. cGMP is the same quality framework that governs pharmaceutical manufacturing, and it means every batch is produced under controlled, documented, and repeatable conditions.

Independent third-party testing

Manufacturing standards alone are not enough. Every compound is tested by an independent laboratory accredited to ISO/IEC 17025, the international standard for testing and calibration laboratories. This testing confirms identity, purity, and potency before a product is released.

Certificates of analysis, on request

A certificate of analysis (COA) is available to approved accounts for any compound they receive. If your clinic ever needs documentation for a specific lot, our team will provide it.

Wholesale only, no exceptions

PSG does not sell to consumers. There is no online checkout and no published price list. Approved accounts submit an order request, and our team confirms availability and issues a manual invoice separately. No payment is ever collected on this site.
