InstaRX
67/100Where the value is
- Flat 'same price any dose' model for both drugs ($179/mo semaglutide, $259/mo tirzepatide) — no dose-tier guesswork
- Free expedited shipping stated explicitly
- States medications come 'exclusively from U.S. pharmacies'
The tradeoffs
- The homepage's own '$199 to get started' figure is never explained anywhere on the site — unclear if it's a one-time signup charge, the first month's payment, or an additional charge on top of the $179/$259 monthly prices
- No medical director or named prescriber anywhere — only generic 'third-party professional healthcare providers' language
Corsica Health
66/100Where the value is
- Publishes real starting dollar prices for THREE tiers on one page — compounded semaglutide, compounded tirzepatide, and brand-name Ozempic/Wegovy — a genuine transparency advantage few competitors offer at once
- Compounded semaglutide's starting price fell from $199/mo to $149/mo since a prior 2026-07-20 check — a real, verifiable decrease
- Free shipping and provider consultation included in the listed starting price
The tradeoffs
- Listed prices are floor figures for the lowest dose tier only — no published ladder for what higher, titrated doses cost
- The '15-20% average weight change' and '4.8/5 satisfaction' figures are the company's own self-reported claims, not independently sourced
