FitRx
59/100Where the value is
- All 50 states + DC coverage
- LegitScript certified
- All four major brand-name GLP-1s (Ozempic, Wegovy, Zepbound, Mounjaro) available if insurance coordination succeeds
The tradeoffs
- The headline '$25/month' price is not a standing self-pay rate — it's an insurance-dependent outcome the site itself hedges with 'roughly', so most uninsured shoppers will pay $151/mo instead
- No compounded tirzepatide offered at all — semaglutide-only on the compounded side
Regulatory note: the FDA issued a warning letter to FitRX, LLC dba FitRx in February 2026. We still list and link to FitRx; you should know the letter is on the public record before you decide.
Invyncible
59/100Where the value is
- Publishes real itemized dollar prices for eight separate combo programs plus two brand options directly on the site, no signup required, with the mg vial size named in every dose option
- Sells FDA-approved brand Wegovy ($1,750/mo) and Zepbound ($1,540/mo) alongside compounded options
- Names all six compounding pharmacies with street addresses and phone numbers and lets the patient choose which one fills the prescription
The tradeoffs
- Every listed price is shown as a discount off a much higher struck-through 'list' price, and the page invites further negotiation — reads as permanent anchor pricing
- The entry figure is the smallest vial: plain compounded semaglutide runs $192.50, $262.50 and $350 across its three vial sizes, and the FAQ confirms cost rises with dose
