Methodology
How we rank UK GLP-1 clinics and pharmacies
PeptideClear ranks clinics and pharmacies offering GLP-1 medications (Mounjaro, Wegovy, Saxenda) for weight management. All listed providers are GPhC-registered. The ranking criteria differentiate within that compliant base.
Inclusion criteria (mandatory floor)
- · UK-licensed pharmacy with GPhC registration verified at listing and annually.
- · Prescriber on payroll or under contract with named GMC registration (not anonymous).
- · Published, transparent pricing on the public site.
- · Published switching, pause, and cancellation terms.
- · At least 12 months of UK trading history for GLP-1 specifically.
- · Public Trustpilot or equivalent review record.
- · No grey-market or compounded GLP-1 supply.
- · Cold-chain delivery infrastructure verified for tirzepatide and semaglutide.
Ranking criteria (weighted)
- Onboarding rigour (20%): full clinical consultation > pharmacist video call > questionnaire-only.
- Coach and check-in cadence (15%): weekly coach plus prescriber > monthly coach > no coach.
- Cost per typical maintenance month (15%): includes medication plus required service fees, normalised to maintenance dose.
- Switching policy clarity (10%): Wegovy to Mounjaro and vice versa with documented washout, restart dose, programme continuity.
- Maintenance-dose policy (10%): explicit maintenance pathway > available on request > not offered.
- Hormonal-context care (10%): HRT or fertility-aware co-prescribing, particularly relevant for women's clinics.
- UK delivery coverage and turnaround (10%): next-working-day UK-wide is the benchmark.
- Trustpilot rating + volume (10%): 4.5+ stars with 500+ reviews scores top.
High-touch vs low-touch differentiation
Clinics are categorised as high-touch (Numan, Voy, Manual, Juniper) or low-touch (Phlo, Pharmacy2U, SimplyMeds, Boots Online Doctor, Asda Online Doctor). The two categories are ranked separately because they serve different user needs. A high-touch clinic ranked first and a low-touch pharmacy ranked first are answers to different questions, not competitors.
What we explicitly do not measure
- · Clinical outcomes for individual users (we do not solicit or publish weight-loss outcomes by name).
- · Brand marketing spend or visibility (top-of-funnel reach is not a ranking signal).
- · Whether the clinic markets to specific demographics in advertising.
Refresh cadence
Rankings are reviewed quarterly. Material change triggers immediate re-review: pricing change > 10%, switching-policy change, GPhC registration change, prescriber turnover at the clinic, Trustpilot rating change > 0.3 stars over 90 days.
Conflict of interest
Some clinics are referral partners. Inclusion is not contingent on a referral relationship; the ranking criteria above apply equally. Affiliate-funded clinics and non-affiliate clinics appear side-by-side in directories.
