Graded #359 · 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
Graded #53 · C
Strengths
- Compounded semaglutide from $83/mo and tirzepatide from $97/mo, billed as one all-in monthly price
- Brand Wegovy, Zepbound, and Foundayo (oral GLP-1) available on the same platform
- US-licensed provider reviews requests within 24 hours — no video visit required
- You aren't charged until a provider approves; checkout places an authorization hold only
- LegitScript-certified; works exclusively with state-licensed US 503A compounding pharmacies
Where it loses points
- Both figures are 'as low as' rates and the qualifying term is not published anywhere — the checkout is gated, so whether $97 is month-to-month or a multi-month prepay cannot be established before signing up
- Brand-name routes are priced separately and do carry a fee: $49/mo membership plus medication from $149/mo for Foundayo and Wegovy, from $299/mo for Zepbound
- No state count is published, and a state-variant waitlist implies some states are unserved
- Compounded semaglutide and tirzepatide are not FDA-approved finished products
