Factor Health MD
67/100Where the value is
- Every plan includes ALL doses at one flat rate with no per-mg escalation, confirmed explicitly in its own FAQ
- LegitScript certified (badge displayed in the site footer)
- Genuinely no long-term contract required for the flexible monthly tier, per its own FAQ
The tradeoffs
- The widely advertised 'From $99/mo' headline (used in the site's own page title) only applies to the 12-month prepaid Annual plan — the real no-commitment month-to-month price is $189/mo for semaglutide and $289/mo for tirzepatide, 91-94% higher
- No compounding pharmacy is individually named, only a generic 'network of licensed, FDA-regulated pharmacies'
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
