Methodology updated: 5 October 2026
This page explains exactly how we produce what you read here, so you can check our work or decide not to trust it.
What we cover, and what we don't
We cover two things: the regulatory status of peptides sold in the United States, and the companies that sell them. We do not cover training protocols, stacks, or how to use anything. Our coverage distinguishes evidence from human studies, preclinical research and company claims. A company profile is not a clinical recommendation.
How we establish regulatory status
Every regulatory claim on this site traces to one of four source types, in this order of preference:
- The Code of Federal Regulations, read on the eCFR — in particular 21 CFR 216.23, the actual 503A Bulks List.
- The Federal Register, for approvals, withdrawals, proposed rules and meeting notices.
- FDA.gov pages and documents, including the 503A and 503B nomination lists and Pharmacy Compounding Advisory Committee briefing materials and minutes. We record the "content current as of" date on every FDA page we rely on.
- Specialist legal and pharmacy trade press — firms like McDermott, Frier Levitt and Buchanan Ingersoll, and outlets like AJMC and Pharmacy Times — clearly labelled as secondary when we use it.
We do not treat a telehealth company, a compounding pharmacy or a peptide vendor as a source for what the law is. We cite them only as evidence of what they themselves claim.
How we establish prices
We record the price shown on the company's own website, the page where it appears and the date of the check. A published price is a company claim, not a guarantee of what an individual will pay.
Where a company advertises an introductory rate, we report both the intro rate and the rate it becomes, and when it changes. Where a headline price requires a multi-month commitment, we say so. Where a company publishes no prices at all, we say that too — it is a finding, not a gap.
Where the only pricing available comes from a company's own paid advertorial, we label it company-claimed and we do not present it as verified.
How we report on a company
We do not rank companies, score them, or tell you which one to choose. We report what each company publishes about itself, attributed to the page it appears on and dated to the day we read it, and we present every company in the same template so you can compare like with like.
The rule we work to is simple. We identify the source and limits of a claim. We attribute what companies publish. Billing and service questions go to the company; personal treatment questions belong with a licensed clinician who knows your history.
Regulatory reporting should link to the relevant primary source and distinguish a final action from a proposal or secondary report. Research coverage should describe what was studied and its limitations. Prices and service terms should be attributed and dated. Ask the company about its charges, cancellation terms and state availability; ask a licensed clinician about treatment suitability and risks.
What we record for every company
The same seven things, in the same order, for everyone:
- What they say they sell
- Prices as listed, with the date we read them
- The clinician and pharmacy they disclose, if any
- Refund and cancellation terms as written in their own documents
- What we could not verify
- The regulatory status of what is on offer
- What to contact them about
What "we could not verify" means
It means what it says: we looked, and we could not confirm it. If a company names a physician, we check state licensing registries, the NPI registry, Healthgrades and Doximity, and we report what we found or did not find. If a company publishes no prices, we say the site displays no prices. If two companies' terms of service name the same pharmacy, we say that, because both documents are public and you can read them yourself.
These are findings about our research, not conclusions about the company. A gap in what we could verify may mean a company discloses less than others, or it may mean we could not find something that exists. We tell you which checks we ran so you can run them too, or ask the company directly.
Where we report a public domain-registration date, we identify it as a domain record. That date does not establish when the company began operating, its clinical experience or the quality of its services.
What we will not do
- We will not publish dosing, reconstitution or administration guidance for any substance that is not an FDA-approved drug.
- We will not link to grey-market "research use only" peptide vendors. If we need to discuss one, we name it without linking to it.
- We will not invent authors, credentials or medical reviewers. If we engage a clinical reviewer, we will name them and you will be able to look them up. Fabricating one is precisely the failure we criticize in others.
- We will not accept payment for inclusion or ranking.
When we get it wrong
We will. This is a fast-moving area and several of the facts we rely on are documented only in trade press because FDA has not published a notice. Where that is true we say so in the article.
If you think something here is wrong, email corrections@getpeptidereviews.com. We check every correction against the primary source and, where we were wrong, we fix the page and note what changed and when. Companies we write about are welcome to use the same address.
Source dates and updates
A source-check date records when the specific claim or source described on that page was checked. An editorial update date can reflect a correction, disclosure or formatting change; it does not mean every legal, medical or pricing statement was checked again.
We do not promise that every page has been re-verified on a monthly schedule or immediately after an agency action. Read the dated sources and update notes on the individual article. When a material claim is corrected, the note should identify what changed, the source used and the date of the check.
This is consumer research about how peptides are regulated and sold. It is not medical advice, and we are not your doctor. Nothing here should be used to start, stop or change any treatment. Talk to a licensed clinician who knows your history.
