The verdict

Too close to callGrade C vs C

FitRx and Invyncible tie on the Cost-Efficiency Index at 59/100, so neither wins outright on the numbers. For most shoppers we'd start with FitRx (ranked #265, a hair above #272) — Cost-first shoppers who want insured patients trying to unlock brand-name GLP-1 access below list price. But Invyncible is a genuine coin-flip alternative here.

Worth knowing either way: our overall #1 pick is CoreAge Rx (Cost-Efficiency Index 94/100 — the top of the ranking). See how it stacks up: CoreAge Rx vs FitRx.

FitRx

59/100

Where 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

59/100

Where 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
