Graded #167 · C
Strengths
- Compounded semaglutide (=Wegovy) and tirzepatide (=Mounjaro); month-to-month from $175/$235, or as low as $99/$125 on annual prepay
- 100% online 4-step process; board-certified provider review in 24-48 hours, with unlimited messaging and dose adjustments
- Free nationwide shipping (discreet, 5-7 days) from US-licensed compounding pharmacies
- FSA/HSA eligible with financing (Affirm, Klarna, Afterpay); month-to-month or prepay plans, cancel anytime
- Transparent 'no hidden fees' pricing; 6,000+ members; same-platform add-ons (NAD+, sermorelin, MIC+B12, glutathione, hair, sexual health)
Where it loses points
- Headline '$99/$125 a month' requires a full year prepaid upfront ($1,188 / $1,500); true month-to-month is $175 / $235
- Compounded medications are not FDA-approved - not brand Wegovy, Ozempic, Zepbound, or Mounjaro
- The compounding pharmacy partner is not named ('US-licensed / FDA-regulated pharmacies' only)
- State-availability list is not published (free nationwide shipping advertised, but no explicit state list)
- No LegitScript certification displayed
