Editorial with affiliate links. We earn from purchases via outbound retailer / clinic links. How we are funded.
Browse UK retailers and clinics by tier. Editorial selections, never paid placements. New to this? Read our guide on how to choose a UK peptide retailer.
PeptideClear is a comparison and information service, not a pharmacy and not a clinic. Every outbound link leads to a third-party operator. Some links carry an affiliate tag: if you make a purchase the retailer pays us a referral fee at no extra cost to you. Retailer inclusion is governed by our methodology, not commercial terms. Read our funding disclosure.
Editorial methodology
Retailers are scored independently on four criteria: certificate of analysis (CoA) transparency, operator Companies House registration, dispatch reliability, and benchmark pricing. Inclusion is never paid. Read our full methodology.

Other UK research-peptide retailers we are still assessing
These are other UK-shipping, research-use-only retailers we are aware of but have not yet scored. We list them in the interest of transparency. Being named here is not an endorsement and not a warning. It means our assessment is incomplete. We only score a retailer once it clears our full 8-point inclusion floor. We do not list retailers that market peptides for human use or make health claims, regardless of data.
Outbound links are unverified and carry no affiliate relationship. Research use only. Not for human or animal consumption.

GLP-1 clinics and pharmacies
