# Vet a Peptide Clinic: The 15-Minute Checklist

A short checklist that sends you to the public registers: the state board, the NPI registry and the FDA 503B list. It ends with a record sheet you fill in for each clinic. Education only, not medical advice.

Price: Free.

## What is included

- Four register checks: prescriber licence, NPI match, pharmacy, red flags
- What 503A and 503B pharmacies mean and where to look each one up
- A one-page record sheet for each clinic you check

> **Not medical advice.** Regulatory status, checked 2026-10-20: FDA rules on the bulk substances a compounding pharmacy may use are in flux. A February 2026 HHS announcement moved about 14 peptides back toward the FDA Category 1 list, and sources disagree on the final status — check the FDA bulk-substances page (https://www.fda.gov/drugs/human-drug-compounding/bulk-drug-substances-used-compounding) before you act. PeptideClinic is a directory, not a clinic or a pharmacy: a listing is a record, never an endorsement. It gives no dosing, no medical advice and no outcome claims, and it never lists research-chemical sellers. Confirm a provider's licence on the named state board, the FDA 503B register or the NPI registry before you book. In an emergency call 911.
