The pharmacies behind the prescriptions

Two providers can dispense from the same pharmacy and charge $200 a month apart. Knowing which pharmacy is behind a price is how you tell a margin from a medicine.

So the single most useful question you can ask a provider is which pharmacy fills your prescription. Of the 22 providers we track, only 3 publish the answer: Likeness Rx and Trimi and PlexusDx. Every pharmacy below is one of them naming a partner publicly — we have not guessed at anybody's supply chain.

Does the pharmacy change what you pay?

Almost never, and that is worth knowing before you shop on it. Providers using the same pharmacy charge wildly different monthly figures, because the gap is their margin and their membership fee rather than the cost of the medicine. Two companies dispensing from the same facility can be $200 a month apart. So pick your provider on price and your comfort on the pharmacy — they are separate decisions, and conflating them costs money.

Pharmacies with enough public detail to assess

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.

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 $129 a month and semaglutide from $79 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.
