Who names their pharmacy
The hardest fact to get out of this market, and the one the FDA’s enforcement actually turns on. Here is who publishes it.
Updated 2026-09-18
Ask most GLP-1 providers which pharmacy compounds your medication and you will not get a straight answer. A small number publish it outright, sometimes with a licence number you can look up.
This matters more in 2026 than it did in 2024. The FDA issued more than 55 warning letters to online GLP-1 sellers in a single action in September 2025, and the distinction between a properly licensed 503A pharmacy and an unlicensed source is exactly what separates a legitimate programme from a dangerous one.

Frequently asked
Why does the pharmacy matter?
Because the pharmacy is what is actually regulated. A 503A pharmacy is licensed by a state board; a 503B outsourcing facility registers with and is inspected by the FDA. Knowing which one made your medication tells you what oversight sat behind it.
How do I check a pharmacy myself?
Ask the provider in writing for the name and whether it is 503A or 503B, then look it up with the state board of pharmacy in the state it operates from. Licences are public records.
What the price does not tell you
A reminder of category: everything priced under roughly $300 here is a compounded preparation the FDA has not reviewed. Two approved oral products now start at $149, and the Medicare programme begins 1 July 2026.
In SURMOUNT-1, adults with obesity lost an average of 19.5% of body weight on 10 mg and 20.9% on 15 mg over 72 weeks. That figure comes from a controlled trial of the active ingredient, not from any particular seller's product.
