Browse UK retailers and clinics by tier. Editorial selections, never paid placements.
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.

GLP-1 clinics and pharmacies
GLP-1 weight-management medications are prescription-only medicines in the UK. Access requires a prescriber assessment. The routes below split into two lanes: high-touch clinics that include coaching and structured programmes, and low-touch online pharmacies offering pharmacy-direct prescribing at lower ongoing cost.
Your prescriber decides which medication, if any, is appropriate for you. PeptideClear does not make medication recommendations.
Clinics
Programme-style clinics with coaching, dietitian access, and structured check-ins alongside the prescriber relationship. Higher monthly cost reflects the support layer.
Best for end-to-end weight programme
