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

- 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

Where it loses points
- Pharmacy partners not named — only described as 'FDA-registered compounding pharmacies'
