The Peptide Catalog.

Every peptide here is prescribed by a licensed medical provider following a Good Faith Exam, then compounded and dispensed by 503A pharmacies through our LegitScript-certified fulfillment partners. Nothing on this page is sold as a research chemical. Compounded medications are not FDA-approved and individual results are not guaranteed.

Why 503A mattersTwo worlds of peptides — read the difference
The 503A Difference

Two worlds of peptides. We only operate in one.

Most “peptides” sold online are not medicine. They are research chemicals, imported and resold under the cover of labels like “not for human consumption” or “for research use only.” The risk profile is not similar to prescribed, compounded peptides. It’s categorical.

Gray Market / Research Chemical

What online peptide sellers ship.

  • No pharmacy license. No state board oversight.
  • No patient-specific prescription. One batch, sold to anyone.
  • No USP 797 sterility standards. No compounding record.
  • No FDA-registered facility. No inspection trail.
  • Label reads “research use only” — because it’s not legally for humans.
  • No name on the vial. No Rx number. No pharmacy name.
  • No accountability if something goes wrong.
503A Licensed Pharmacy

What Forbidden Rx delivers.

  • Licensed pharmacy, state board of pharmacy oversight.
  • Patient-specific prescription — compounded for you.
  • USP 795, 797, and 800 sterility and quality standards.
  • Subject to regular FDA and state inspections.
  • Prescribed by a licensed provider in your state.
  • Your name on the vial. Rx number. Pharmacy name. Lot number.
  • Full accountability — licensed parties, traceable chain.

The simplest test: is your name on the vial?

Federal law requires 503A compounding pharmacies to label every patient-specific prescription with the patient’s name, the prescription number, and the pharmacy’s identification — the same legal standard as any prescription you’d pick up at a regular pharmacy.

If a peptide you received — from any source, at any point in the past — did not carry your name, a prescription number, and a licensed pharmacy’s name, it was not compounded under the laws that require sterility testing, patient-specific verification, and pharmacy oversight.

That isn’t a labeling technicality. It’s the reason the labeling exists. Without it, there’s no way to know what you injected, where it came from, or who is accountable.
