Five checks, all free, all primary sources, about five minutes. Every one requires the name of the fulfilling pharmacy — which is why a provider that will not name it has removed your only route to independent verification. Start there.

The five checks, in order of what they rule out

Verification sequence
#CheckWhat it rules outWhere
1Get the pharmacy name in writingEverything below is impossible without itThe provider
2State board licence lookupAn unlicensed or disciplined pharmacyEach state board's register
3FDA warning lettersA pharmacy with documented federal findingsFDA warning letter database
4503B registrationA false claim to outsourcing-facility statusFDA registered facilities list
5Drug recall databaseRecent recalls involving the firmopenFDA

Steps 2 to 5 are searchable by company name and free.

The one answer that ends the process. A refusal to name the pharmacy is not a privacy position — the name appears on the label of what arrives at your door. It means you cannot run steps 2 through 5, which are the only independent checks available to a buyer. Treat it as the answer, not as a missing answer.

What each check cannot tell you

The five questions to send in one email

  1. Which pharmacy fills this prescription, and is it 503A or 503B?
  2. What is the exact salt form and concentration, in mg/mL?
  3. Are there added ingredients — B12 or anything else — and at what concentration?
  4. What is the price at a maintenance dose, not the starting dose?
  5. What is refunded if I stop during titration?

Answers in writing to all five is a good sign. Answers to three of five tells you which two they would rather not put in writing, and that is information too.

Five minutes total against a decision costing $1,700 to $4,200 a year.

Why this matters more than any review score

A review score is someone's judgement. A state board register is a public record. When the two disagree, the register wins — and it is the one almost nobody checks, because it requires a name that most providers do not publish.

What the checks look like when they come back badly

The last row matters: passing every check confirms permission to operate, not product quality.

Common questions

Is a provider with a warning letter automatically bad?

Read what it was about. Warning letters cover everything from labelling language to serious manufacturing findings, and the difference is substantial. A letter specifically about compounded GLP-1 preparations or salt forms is directly relevant; one about a marketing claim on an unrelated product is weaker evidence.

Why does the salt form question keep coming up?

Because it is the specific thing the FDA has objected to, and because it is invisible without asking. Semaglutide sodium and semaglutide acetate are not the same active ingredient as the base form in approved products. No licence check surfaces this — only the provider can answer it.

What if the pharmacy is licensed in a different state to me?

Normal. Pharmacies commonly hold non-resident licences to ship into other states, and that licence is also checkable on your own state's board register. What must be licensed in your state is the prescriber.

What a good answer looks like, verbatim

It is easier to recognise a sufficient answer than to describe one. These are the shapes worth looking for.

On the pharmacy: a name, a state, and a category. "Compounded by [Name] Pharmacy, a 503A pharmacy licensed in [State], non-resident licensed in yours." Everything checkable follows from that.

On formulation: "Semaglutide base, 2.5 mg/mL, no additional active ingredients." Base rather than a salt, a concentration in mg/mL, and an explicit statement about additives. If B12 or anything else is included, it should be named with its own concentration, because it was in no trial.

On price: "$X per month at every covered dose from 0.25 to 2.4 mg, no membership fee, billed monthly." A figure, a dose range in milligrams, an explicit statement about fees, and a billing term.

On refunds: "Cancel any time before the next fill; unshipped months refunded." Specific enough to hold them to.

The answers that should end the conversation

Marketing phrase against regulatory reality
PhraseReality
"FDA-approved pharmacy"The FDA does not approve pharmacies
"FDA-registered facility"True of 503B facilities. Registration is not approval
"Pharmaceutical grade"Not a regulatory category
"Clinically proven formula"No compounded preparation has a trial of its own
"Physician-formulated"Not a standard, and not a substitute for one

None of these is illegal to say. All of them describe something other than what a reader hears.

How many of the five checks a typical provider makes possible
Names its pharmacy publicly1Names it on request3States 503A or 503B2States the salt form1Publishes a maintenance price2

Indicative of what we see across this market, on a five-point scale. The first row is the gate: without it, four of the five public checks cannot be run.

What this page does not settle

What the five checks do settle is whether the basic claims are true, and that is more than most buyers establish before spending two thousand dollars a year.

Not medical advice. This page reports what published trials and manufacturers state. It is not a diagnosis, a dosing instruction or a recommendation for any individual. Every efficacy figure here was collected on an FDA-approved product; no compounded preparation has a trial of its own. Talk to a licensed clinician before starting, changing or stopping any medication.
