Graded #289 · C
Strengths
- Offers both compounded semaglutide and tirzepatide, with every dose priced the same so cost does not rise as you titrate up.
- LegitScript-certified (seal #51079066) and names both its 503A compounding pharmacy, VialsRx, and its provider network, Beluga Health.
- Transparent tiered pricing with a real month-to-month option; consultation, medication, and free expedited shipping included, no membership.
- Available in all 50 states with same-day provider review; no insurance needed and HSA/FSA accepted.
Where it loses points
- Very new (2026 launch) with a thin track record; the site still shows a Webflow template credit and a leftover Cora reference in its Terms.
- The cheapest headline rates ($99 semaglutide / $135 tirzepatide) require a 12-month prepay; true month-to-month is $175 and $225.
- Both product pages currently display an out-of-stock status, so availability may be inconsistent.
- Compounded medications are not FDA-approved or therapeutically equivalent to Ozempic, Wegovy, Mounjaro, or Zepbound.
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
