Why this site exists
Millions of people in the UK are now taking these drugs, or thinking about it. The good information about them already exists. It is just spread across regulatory documents, trial papers and clinical references that were never written for the public, and almost everything written for the public is written by somebody selling something.
01The problem
Search any compound in this register and look at what comes back. Most of the first page will be pharmacies, clinics and peptide vendors. Those pages are not lies, exactly. They are accurate enough to be defensible and shaped throughout by the need to end in a sale.
Meanwhile the genuinely authoritative material is sitting in the open, free to read, and practically nobody reads it. A Summary of Product Characteristics tells you precisely what a medicine is licensed for and lists every side effect by frequency. It is also fifteen pages of regulatory prose. The BNF is written for prescribers. NICE appraisals are written for commissioners. Trial papers are written for other researchers.
Between documents nobody can read and content nobody should trust, there is very little. That gap is what this site is for.
02What we do about it
Every compound gets one record, and every record follows the same six sections in the same order: what it is, its UK legal and licensing status, how it works, what the evidence shows, reported harms, and sources. Same structure every time, so you can compare two compounds without learning a new layout.
UK status comes first on every record, before anything else, because it is the single most useful fact and the one most often blurred elsewhere. Licensed medicine, unlicensed, and research use only are three completely different positions in law and in safety, and knowing which one applies tells you whether anyone independent has ever examined the product.
Every claim is traced to where it came from. Where a number comes from a trial, the trial is named and so is the company that funded it. Where there is no human evidence, the record says so plainly rather than substituting animal data and hoping you do not notice.
03Keeping it current
This field moves faster than almost anything else in medicine. In the first half of 2026 alone, a GLP-1 arrived in tablet form in the UK, the MHRA updated product information over pancreatitis risk, tirzepatide prescribing for obesity moved into the GP contract, and the regulator opened an investigation into clinics selling unlicensed peptides.
Anything written about this subject and left alone is wrong within months. So every record carries the date it was last checked, and the news page tracks what changes: MHRA decisions and safety alerts, NICE and NHS access changes, published trial results, and enforcement action. Negative trial results are recorded the same as positive ones, because a drug failing to do something is exactly as informative as it succeeding, and it is the half of the story that never travels.
04How this pays for itself
It does not, and that is deliberate.
The site sells nothing. No advertising for medicines or supplements, no sponsored placements, no affiliate links, no paid listings, no money from any company that sells any compound listed here. There is no "compare providers" table and there never will be.
The reason is not modesty. A site that both explains a compound and earns money when you act on the explanation has an interest in what you conclude, and you can never fully tell how much that interest shaped what you read. Removing the interest is the only way to make the writing trustworthy. It also happens to be the one thing a commercial competitor cannot copy.
If that ever changes, the editorial policy will say so first, prominently, before the change appears anywhere else.
05What this site is not
- Not medical advice. It is a reference. It knows nothing about you, your history, your other medicines or your circumstances, all of which change what is safe.
- Not written by clinicians. It gathers and cites published work by people who are. Where a claim is contested or thin, it says so instead of pretending to authority it does not have.
- Not a pharmacy, clinic or supplier. Nothing is for sale and no route to buying anything is provided, including for compounds that are entirely legal to obtain with a prescription.
- Not a source of doses or protocols. Not for anything, licensed or not. Dosing is a clinical decision made by someone who knows your history.
If you are considering any compound listed here, speak to a doctor or pharmacist. If you have taken something and feel unwell, contact NHS 111, or 999 in an emergency. Suspected side effects from any medicine can be reported through the MHRA Yellow Card scheme.
06Who writes it
Peptide Register is run independently from Teesside in the north east of England. It is not a company, a clinic, or a charity, and it has no connection to any manufacturer, supplier or prescriber of anything in the register.
Some of what is here will go out of date, and some of it will simply be wrong. If you find an error, say what it is and where the correct information comes from, and it will be fixed openly with the checked date updated. Corrections are not made quietly.
