Graded #50 · C
Strengths
- $119/mo all-in including medication, 1:1 physician consults, and unlimited messaging ($100-off-for-life intro promo)
- Both compounded (injectable + sublingual semaglutide/tirzepatide) and brand GLP-1 (Wegovy, Zepbound)
- Integrated fitness and nutrition/behavioral coaching (linked to the BodyFX brand)
- Publishes Terms, Privacy, and data-privacy policies; links to LegitScript verification
Where it loses points
- Promo-driven landing page; compounding pharmacy and legal entity not named
- Tirzepatide and brand pricing may differ from the advertised $119/mo plan
- LegitScript status links to a CAPTCHA-gated checker — not independently confirmed here
- Exact drug and dose are shown only after the intake quiz
Graded #282 · C
Strengths
- Publishes plan pricing openly, before any intake or account creation
- Month-to-month with no long-term contract and no multi-month prepayment
- Billing starts only after a licensed provider approves treatment
- LegitScript certification verified against the issued seal, not just the badge
Where it loses points
- Its own pricing page contradicts itself: it claims no separate consultation charges, then states a $25-$60 fee applies per visit
- The consultation fee is charged whether or not a prescription is issued
- Advertised $129 and $199 rates are time-limited founding rates; standard rates are $249 and $299
- No compounding pharmacy is named anywhere on the site
- Shipping claims conflict: a 48-hour figure on the homepage against 1-2 days to ship plus 2-3 days transit in the FAQ
