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 #4 · B
Strengths
- Available in all 50 states
- Transparent, all-inclusive published pricing — consult, medication, supplies, shipping and support, cancel anytime, from ~$194/mo compounded semaglutide on an annual plan
- Both injectable and a real oral (capsule) route, plus compounded and an advertised brand-name lane
- Physician-led by a named, board-certified founder (Dr. John Diaz) with 24/7 messaging and coaching
Where it loses points
- Compounded semaglutide/tirzepatide are not FDA-approved (not the same as Wegovy/Ozempic/Zepbound)
- Published pricing is for the compounded line — brand-name pricing isn’t itemized
- A prescription isn’t guaranteed — a provider reviews eligibility after checkout
