Graded #45 · C+
Strengths
- As low as $1/day ($25/month) for brand-name Foundayo with insurance and the auto-applied Lilly coupon
- Same-day delivery in nearly 3,000 US cities at launch, expanding to 4,500 by end of 2026
- In-office pharmacist kiosks at select One Medical clinics let you walk out with Foundayo in hand
- Cash-pay $5/day ($149/month) is competitive for the same FDA-approved brand-name product
- Real-time availability, transparent pricing, and automatic manufacturer coupon at checkout
Where it loses points
- Headline $25/month needs both insurance and the Lilly Savings Card — uninsured pay $149/month
- Same-day delivery is geographically gated; outside major cities it drops to next-day or slower
- Pricing is set by manufacturer savings programs and can change at any time
- No compounded options — brand-name only (Foundayo, Wegovy, Zepbound)
- Wegovy/Zepbound pricing isn't shown upfront — depends on insurance at the prescribing visit
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
