How to tell a regulated GLP-1 seller from a risky one

Most advice on this subject is written as though the market divides cleanly into legitimate companies and criminals. It does not. The regulator actions on record in this market reach household names and manufacturers as readily as they reach anonymous vial sellers, and the genuinely dangerous end — unlicensed pens sold through social media — rarely looks like a company at all. So the checks below are ordered by how much they actually tell you.

Start with what is on the public record

12 is not a small number out of 87, and the composition matters more than the count: 9 of the flagged services sell compounded medication and 3 sell brand-name product. The brand tier is the better-evidenced product. It is not the tier with a clean regulatory record.

The checks that are worth your time

Ask which pharmacy dispenses, then check the pharmacy

Only 40 of 87 services name the pharmacy or outsourcing facility that fills the prescription. In Britain the check is quick and conclusive: the General Pharmaceutical Council publishes a register of pharmacies and pharmacy professionals, and a legitimate UK online pharmacy will be on it. A site that will not name its dispensing pharmacy has removed your only means of verifying anything about the medicine.

Read what the seller says about FDA status, in its own words

The claim to watch is not “this is FDA-approved” — few say that outright. It is “made in an FDA-registered facility”, which is a real statement about a building and no statement at all about a medicine. FDA does not approve or license compounding pharmacies, and the agency has sent warning letters to telehealth companies specifically for implying it does. The services that handle this honestly say so plainly; Noom’s own wording draws the distinction that its product “has not been reviewed by the FDA for safety, efficacy, or quality.”

Treat a vial and a syringe as a dosing hazard

FDA has issued a specific alert about dosing errors with compounded GLP-1s, arising because a multi-dose vial moves the arithmetic from the manufacturer to the patient. Units on a syringe are not milligrams, and the conversion depends on the concentration your particular pharmacy used. If a seller ships a vial without telling you the concentration in writing, that is a concrete safety failure rather than a stylistic one. The ladders it applies to are in Every dose step, and what to do when you miss one.

Notice what the intake does not ask

These drugs carry a boxed warning for thyroid C-cell tumours and are contraindicated with a personal or family history of medullary thyroid carcinoma or MEN 2. They also delay gastric emptying, which changes the absorption of other oral medicines. An intake that asks neither about that family history nor about your current medications is not screening you. That is the single most informative thing you can observe for free, and it is item two and item five on Thirteen things a GLP-1 service should tell you before you pay.

Two things that look like red flags and are not

• ◆A British site that will not show a price. Only 2 of 20 UK services publish an entry price, against 57% in the US, and the reason is CAP Code rule 12.12 — advertising a prescription-only medicine to the public is prohibited, and a price is advertising. The ASA has been enforcing this actively. In Britain, price silence is compliance; see Why UK GLP-1 pages tell you so much less.
• ◆A consultation that is a questionnaire rather than a video call. Asynchronous prescribing is lawful and widespread, and a well-built questionnaire can screen better than a rushed call. What matters is what it asks, not what medium it arrives in.

And one gap this site could not close

Two companies appear in the sweep often enough to matter and could not be verified at all: they are published in a documented-gap table on the reviews index with their indexed search fragments shown and labelled unverified, rather than being written up from general knowledge. 2 entries is not many, but the most-referenced domain in the entire sweep is among them. Where a fact could not be retrieved, this site says so instead of filling it in — which is the same standard worth holding a seller to.
