About peptidefix
peptidefix is an independent directory of peptide suppliers, compounding pharmacies and research papers. It sells nothing, and no company pays to be listed. This page is how the directory chooses what to publish, and how to ask for a correction.
Founded by Nick, in the UK.
What peptidefix is
- An independent directory. It lists 49 peptide suppliers in the UK, the US, Australia and Europe, 28 peptide pages, 29 compounding pharmacies and 172 research papers.
- It does not sell peptides, or anything else. No supplier pays to be listed. Listings are alphabetical. peptidefix does not rank suppliers, score them, or call any of them best, trusted or verified.
- A listing records what a company says on its own website. peptidefix does not test products, check certificates of analysis, show prices or link to product pages. The rules are on How we list.
How research papers are chosen
- A paper is added when it concerns a peptide the directory covers and it can be tied to the paper itself, usually by a DOI. Supplier blogs, forums and news articles are not treated as papers. A person reads the record before it is published.
- Each paper is labelled by study type: human study, animal study, cell study, review, meta-analysis, preprint or regulatory note. The summary says what was studied, in what and how many, and it links to the source. Preprints are labelled as not peer-reviewed. A regulator’s decision can be filed as a regulatory note.
- The “Most-studied peptides” list on the home page is a separate count of human clinical trials, not a measure of whether a peptide works. The searches behind it are on How we list.
- Summaries state what a study did and what it found, including limits the authors note. They are not medical advice, and they give no dosing.
How listings stay up to date
- Every supplier listing is drawn from the supplier’s own website: where it operates, where it ships, the peptides it lists that have a page here, and its stated terms in its own words. The company name and registration number are copied as the site shows them, with the date, or marked “Not shown”.
- A person reads each listing before it appears. Each country’s listings are re-checked about once a month for changed terms, catalogue and shipping.
- Each pharmacy on Compound Labs is listed from its own public pages, with its licence checked against the regulator’s register where one is public. Australian listings never show which peptides a pharmacy names: Australian law restricts advertising prescription-only medicines to the public.
How legal status is sourced
- Each peptide’s status in the UK, the US and Australia is checked against the regulator (the MHRA, the FDA and the TGA) and dated on the peptide’s page. The full table is on Legal status.
- Europe is a tab for suppliers and compounding pharmacies. Legal status is not recorded for Europe.
- A status line is what the directory understood on the date shown. It is not a ruling for a reader’s own situation. Verify it with the regulator.
Corrections
- If a page is wrong or out of date, email info@peptidefix.io with the page and what has changed. peptidefix checks the change against the supplier, the pharmacy, the regulator or the paper before editing.
