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 #61 · C
Strengths
- Compounded semaglutide from $149/mo and tirzepatide from $199/mo, plus a $129/mo microdose option
- Flat pricing — the same monthly cost at every dose as you titrate up
- All-inclusive: medication, unlimited 24/7 provider messaging, and free shipping bundled in
- Names its compounding pharmacy — Strive Pharmacy (licensed 503A)
- Available in all 50 states with same-day approvals
Where it loses points
- Operates as a technology platform, not the medical provider itself
- Compounded GLP-1s are not FDA-approved (the site discloses this honestly)
- Aggressive marketing results claims (e.g. '18% average', '93% kept it off') with 'results not typical' disclaimers
- Legal entity name not published (footer shows only 'Zera Health')
