The pharmacies behind the prescriptions

When you buy a compounded GLP-1, the telehealth company is not making your medication. A compounding pharmacy is, and that pharmacy is the entity a state board actually licenses and inspects.

So the single most useful question you can ask a provider is which pharmacy fills your prescription. Of the 21 providers we track, only 2 publish the answer: Trimi and PlexusDx. Every pharmacy below is one of them naming a partner publicly — we have not guessed at anybody's supply chain.

Pharmacies with enough public detail to assess

Also named, with less public detail

• GreenwichRx — named by Trimi. Named alongside VialsRx as a 503A compounding partner. No FDA entry found.
• Casa Pharma Rx — named by PlexusDx. Published contact number 877-937-6868. No FDA entry found.
• The Pharmacy Hub — named by PlexusDx. Published contact number 888-958-1382. No FDA entry found.
• Foothills Pharmacy — named by PlexusDx. Published contact number 480-496-4444, an Arizona number. FDA lists a Foothills Professional Pharmacy, Ltd. in Phoenix, AZ (503A) with a 2020 warning letter that was closed out in 2022 — we could not confirm these are the same entity, so we are not attributing that record here. Ask the provider for the pharmacy’s full legal name.

These have pages nowhere on this site because we could not verify enough about them to justify one. That is a statement about available information, not about the pharmacies.

Named in industry roundups, unverified by us

These names appear in published lists of GLP-1 compounders where our only source is a single third-party roundup — and several of those roundups are published by pharmacies that rank themselves first. We record them as leads so you can recognise a name, not as findings.

• Newtropin — 503A, peptide-focused. Our only source is its own roundup, which ranks itself first. No FDA entry found.
• LS Compounding — Weight-management focus, flat-rate overnight shipping reported. No FDA entry found.
• Innovation Compounding — Integrative medicine focus. No FDA entry found.
• Compounding Pharmacy of America — Value-focused national compounder. No FDA entry found.
• Central Drugs Compounding Pharmacy — California, long-established. No FDA entry found.
• University Compounding Pharmacy — San Diego specialty compounder. No FDA entry found.
• Red Rock Pharmacy — Named in patient discussion as a wholesale compounder. No FDA entry found.
• Southend Pharmacy — Named by patients in public forums. No FDA entry found.
• IvyRx — Described in one roundup as a 503B option. No FDA entry found.

What the FDA record adds

Every pharmacy page here carries that facility’s entry from FDA’s published inspections and actions list. It is worth doing because published rankings and published enforcement records do not always agree: one pharmacy in this set is recommended in an industry roundup specifically for its safety focus, while its FDA record contains a 2022 voluntary recall for sterility issues serious enough to warrant an FDA press release. Both facts are on its page.

Read those records with the glossary rather than the headline. A Form 483 is inspection observations, not proven violations; a close-out means FDA confirmed resolution; and no entry at all frequently means no inspection rather than a clean result.

What the pharmacy actually determines

• The concentration of your vial. Compounded preparations are not standardised between pharmacies, and concentration is what turns your prescribed dose into the volume you draw.
• The beyond-use date. Compounded products carry one instead of a manufacturer expiry, and it is typically much shorter.
• Sterility and potency practice. 503A pharmacies work to USP standards including USP 797 for sterile preparations.
• Whether anyone has inspected the place. State licensure is mandatory; PCAB and NABP accreditation are voluntary and involve on-site inspection.

How to verify any compounding pharmacy yourself

1. Ask your provider, in writing, to confirm this is the pharmacy filling your prescription and whether it is a 503A pharmacy or a registered 503B outsourcing facility.
2. Look the pharmacy up on the state board of pharmacy website for the state it operates from. Boards publish public licence lookup tools, and licences are public records.
3. Check whether it holds voluntary accreditation. PCAB accreditation is administered through ACHC, which publishes an accredited-organisation search; NABP runs its own three-year Compounding Pharmacy Accreditation and provides a form for checking status.
4. Ask for a certificate of analysis for your batch. Most will not offer one unprompted; the response you get is informative either way.
5. If your provider will not name the pharmacy at all, that is the answer to your question — see how to spot a bad seller.

Accreditation is voluntary and its absence is not proof of a problem — plenty of properly licensed pharmacies do not carry it. Both NABP and PCAB evaluate compliance with USP standards through on-site inspection and documentation review, which is why it is a meaningful signal when present.

The thing worth repeating

Where to get a GLP-1 prescription

A compounding pharmacy cannot sell you a GLP-1 directly — it fills a prescription written by a licensed clinician. So the practical route is a telehealth provider who prescribes and arranges dispensing.

Our featured provider is [Coreage Rx](/reviews/coreage-rx-tirzepatide-reviews), which prices compounded tirzepatide from $149 a month and semaglutide from $99 on the annual plan, flat at every dose and with no membership fee. That is a paid placement and we say so on every page it appears — see our disclosure. Check current pricing.

If you would rather avoid the compounding question altogether, two FDA-approved oral GLP-1s now start around $149 a month — see the approved pills. The cheapest compounded route we track is Trimi at $125 a month.
