How We Compare Weight Loss Medication Providers

Transparent, evidence-based methodology. No pay-to-rank listings. No hidden biases.

Our Comparison Criteria

Every provider on WhichWeightMeds.org is evaluated against six key criteria. We do not accept payment to rank providers higher — our listings are based purely on these factors.

GPhC Registration

We verify every provider against the General Pharmaceutical Council register. Only pharmacies with active, valid registration are listed.

Essential — no listing without it

GPhC Register

Pricing Transparency

We compare the starting monthly price for each medication. Prices are taken directly from provider websites and include the consultation fee where applicable.

Updated regularly

Medication Availability

We check which medications each provider offers (Mounjaro, Wegovy, Saxenda) and whether they are currently in stock.

Checked weekly

Delivery Speed

We record delivery options including same-day dispatch, next-day delivery, and in-store collection where available.

Self-reported by providers

User Reviews

Rather than hosting our own reviews (which can be manipulated), we link directly to each provider's Trustpilot profile so you can read verified, independent reviews.

Independent via Trustpilot

Trustpilot

Clinical Support

We note whether providers offer ongoing clinical support, follow-up appointments, and lifestyle guidance as part of their service.
