How we review & rank
TopGLP1 covers prescription medications and money — so how we source facts, rank programs, and fund the site should be transparent. Here's exactly how we work.
Last updated 2026-09-01
Where our medical facts come from
Every clinical claim on this site — average weight loss, dosing, side effects, approval status — traces to a primary source: peer-reviewed trials published in the New England Journal of Medicine, or official FDA guidance. We link the primary record on each page so you can verify it yourself. We do not cite other blogs, and we do not present figures we can't source. Where evidence is early or mixed (as with the investigational drug retatrutide), we say so plainly.
How we rank providers
Our provider rankings weigh the factors that actually affect a patient: real price (and whether it's compounded or branded), which medications and formulations are offered, pharmacy accreditation and the clinician model, shipping, insurance stance, and commitment terms. We surface the trade-offs rather than reducing everything to a single score, because the right program genuinely depends on your priorities and your insurance.
How we handle pricing
Prices are provider-reported and change frequently — and compounded-drug availability shifts with FDA shortage status. We publish the figures providers state, flag clearly when a price isn't publicly fixed, and tell you to confirm current rates on the provider's own site before enrolling. We never invent a price to fill a gap.
How we make money
TopGLP1 earns affiliate commissions when readers sign up with some of the providers we feature. That funds the site and keeps it free. It does not change our medical explanations, and a provider's ranking is not for sale — a program we're paid by can rank below one we aren't. Outbound affiliate links are marked as sponsored.
What we do
- Cite every clinical figure to NEJM or the FDA
- Disclose affiliate relationships openly
- Rank on merit, independent of who pays us
- Flag uncertainty and unproven claims
- Update pricing and re-check sources over time
What we don't do
- Invent statistics, prices, or fake reviewers
- Let affiliate deals dictate rankings
- Give medical advice or replace your clinician
- Promote unapproved or illegally sold drugs
- Publish AI-generated filler in place of substance
