Peptide therapy in the UK: regulated clinics vs vial resellers

01The short version

"Peptide therapy" in the UK means two very different things: regulated clinics prescribing licensed peptide medicines (mostly GLP-1s for weight, occasionally growth hormone for deficiency), and wellness or longevity clinics offering unlicensed research peptides under a medical-sounding label. The first is medicine. The second is the research-vial market with a consultation fee. Here is how to tell them apart.

02Regulated peptide prescribing

A GMC-registered doctor can prescribe a licensed peptide medicine for its licensed use, or off-label where they can justify it. Weight management with semaglutide or tirzepatide through a CQC-registered clinic or pharmacy is the mainstream example. You get a consultation, a prescription, a pharmacy-dispensed product and follow-up. Ask for the CQC registration and the prescriber's GMC number; both are public.

03'Peptide protocols' from longevity clinics

Some UK clinics offer BPC-157, TB-500, ipamorelin, CJC-1295, epitalon or GHK-Cu as injectable "protocols" for recovery, anti-ageing or performance. None of these is a licensed medicine. A doctor prescribing an unlicensed product takes personal responsibility for it and must be able to justify it clinically, which for these compounds is hard, because the human evidence is thin. Some clinics avoid the word "prescribe" and sell the vials as research chemicals with a "consultation" attached, which is the ordinary vial market at a premium.

04Questions to ask any peptide clinic

1. Is the product licensed in the UK? If not, on what basis is it being supplied?
2. Who is the prescriber, and what is their GMC number?
3. Is the clinic CQC-registered?
4. Which pharmacy or manufacturer supplies the product, and is there a batch certificate?
5. What human evidence supports this protocol for my goal?

05Where nootropic peptides fit

Semax and Selank are not prescribed in the UK and do not need a clinic. They are sold as supplements for healthy adults, with the evidence and its limits set out openly. That is a different model from peptide therapy: no consultation fee, no injection, a published assay, and a 30-day guarantee. The Semax guide covers it.

COGENT makes two peptide nasal sprays, Semax (FOCUS-01) and Selank (CALM-02), and nothing else. We do not sell the compounds discussed below and this article does not recommend buying them. It exists because people search for these things and deserve an honest answer.
