How we compare providers
How cleardose collects and verifies provider data, how the ranking algorithm works, what our independence policy covers, and how to report errors.
What we track
cleardose tracks 42 GPhC-registered UK providers offering private prescriptions for Mounjaro (tirzepatide) and Wegovy (semaglutide). We do not include providers offering unlicensed, compounded, or unregulated GLP-1 products. Every provider in the comparison tool has been verified as GPhC-registered at the time of inclusion.
For each provider and drug/dose combination, we collect and maintain the following data:
| Data field | What it captures | Update frequency |
|---|---|---|
| Ongoing monthly price | Standard monthly cost at each dose for a continuing patient. Includes medication and standard delivery where bundled. Excludes separate consultation fees unless stated as included. | Weekly |
| First-month / introductory price | Where a provider offers a reduced price for the first order, we capture this separately. Used when ranking for "best first-order deal." | Weekly |
| Recurring discounts | Permanent or subscription-based price reductions that apply to every order, not just the first. | Weekly |
| Delivery cost | Standard delivery charge per order, if not included in the medication price. Providers with free standard delivery are scored accordingly. | Weekly |
| Dose transfer policy | Whether the provider will accept incoming patients at a dose above the starting 2.5mg / 0.25mg, and the evidence they require to do so. Captured in milligrams accepted for transfer. | Monthly |
| Trustpilot rating | Verified Trustpilot score as published. We use the published score; we do not independently verify or audit reviews. | Monthly |
| Programme tier | Whether the provider is a pharmacy-only dispensing service, or a programme provider offering coaching, dietitian support, or structured behaviour change alongside medication. | Quarterly |
| NHS linkage | Whether the provider has a documented connection to NHS weight management services or offers NHS referral pathways. | Quarterly |
How rankings work
Rankings are calculated in real time based on user inputs — medication, dose, patient type (new patient or switcher), and optional preferences. The same provider will rank differently for different users. There is no fixed league table.
The primary signal: price for your situation
The dominant ranking factor is effective price — but the price we use depends on what you've told us:
- If you've set a weight goal — we calculate the estimated total cost of treatment from your current dose to your goal weight, including the escalation phase and ongoing monthly cost at maintenance. This is the most accurate way to compare true treatment cost.
- If you're a new patient without a goal — we blend first-month and ongoing prices (weighted 1:5) to reflect that new patients care about both the start and the long-term cost.
- If you're an active switcher — we rank on ongoing monthly price only, since you're not going through first-month pricing again.
- If you've selected "best first-order deal" — we rank purely by first-month or introductory price.
Preference signals
When you select preferences in the comparison tool, they adjust the scoring weights applied to each factor. No preference overrides price entirely — they shift emphasis. The dimensions and their weighting behaviour:
Providers with no price data for the selected drug and dose are excluded from results entirely rather than ranked last. A provider that doesn't offer a specific dose should not appear as an option for that dose.
Data collection and verification
Prices are checked weekly by our team directly from provider websites and order flows. We check both the listed price and the checkout price where these differ. Where a provider shows different prices for different membership or subscription tiers, we use the standard non-membership price unless the membership is clearly free.
We do not rely on provider-submitted data. Providers cannot update their own listings, request changes to their ranking, or submit promotional information for inclusion. All data is collected independently.
Despite weekly checks, prices can change between updates. We display the date of last update on the comparison tool. If you find a discrepancy between a listed price and the price you see on a provider's website, please report it using the contact details below.
On Trustpilot ratings: We use published Trustpilot scores as a proxy for patient experience because they're independently verified and publicly available. We acknowledge their limitations — review volume, recency, and category vary between providers. We do not weight Trustpilot heavily in default rankings; it becomes significant only when the user explicitly selects it as a preference.
Independence policy
Editorial policy for guide content
The guides and articles published on cleardose are written by our editorial team and reviewed for clinical accuracy against published trial data and MHRA/NICE guidance. We do not accept sponsored content, native advertising, or paid article placements.
Where we describe clinical evidence, we cite the relevant trials. Where evidence is uncertain or emerging, we say so. Where a claim requires clinical judgement rather than established evidence, we flag it as such.
Guides are updated when significant new evidence emerges — for example, the addition of the Wegovy 7.2mg dose in January 2026, or new cardiovascular trial data. The last-updated date appears at the top of each article.
What we don't claim
- We are not a medical authority. Nothing on cleardose constitutes medical advice.
- We are not a regulator. We cannot verify GPhC registration in real time; we check it at point of inclusion and periodically thereafter. Always verify a provider's registration at pharmacyregulation.org before starting treatment.
- We cannot guarantee that a listed provider has stock of a specific pen at any given time. Supply availability changes frequently and is not something we can track in real time.
- Price rankings reflect publicly available pricing. Providers may offer different prices via telephone, email, or non-public promotions that we cannot capture.
- Trustpilot ratings reflect user reviews at time of collection and are not independently verified by cleardose.
Reporting errors and updates
If you find a price that differs from what we show, a provider whose GPhC registration has changed, or any other factual error in our comparison data or editorial content — please let us know.
Contact us at [email protected] with the provider name, the discrepancy you've found, and a source where possible. We aim to review and update within 48 hours for price corrections.
If you are a provider and believe your listing contains an error, please use the same contact address. We will correct factual errors promptly. We do not accept requests to change ranking position, add promotional content, or remove accurate data.
About cleardose
cleardose was built in 2026 by a team with a background in health information and consumer advocacy. It exists because the UK GLP-1 market is large, commercially driven, and difficult for patients to navigate without a resource that has no stake in which provider they choose.
The site is not affiliated with any provider, pharmacy group, pharmaceutical manufacturer, or investment vehicle with interests in the GLP-1 space.
If you're a journalist, researcher, or policy professional looking to cite cleardose data or methodology, please contact us at [email protected]. We're happy to provide additional context on data sources and methodology.
