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 #358 · C
Strengths
- Competitive entry pricing: semaglutide from $228/mo and tirzepatide from $280/mo with medication + supplies included
- Nurse-practitioner-led care: founder Tasha Vangile FNP-C (20+ years) and Stephanie Robison APRN-CNP (27 years experience)
- Low-cost $99/mo GLP-1 microdosing option for patients who prefer a gradual titration start
- Strive Pharmacy partnership implies compounded 503A-quality supply chain from a known pharmacy
- Multi-modal clinic: GLP-1 + peptides + HRT + nutrition coaching available under one provider team
Where it loses points
- Only 8 states (NC, CO, ME, VT, VA, IA, NH, PA) — excludes the majority of the US
- No LegitScript certification; credentialing evidence limited to local 2025 Best of Iredell award
- Specific drug names (semaglutide/tirzepatide) never stated on website; compounded status inferred, not disclosed
- Labs not included or mentioned; no baseline bloodwork protocol published
- Pricing shown as 'Starting at' with no dose-escalation tier pricing disclosed publicly
