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
