Graded #416 · C
Strengths
- Both compounded semaglutide and tirzepatide available
- Per-dose purchasing — no subscription or membership required
- 25% off plus free shipping promotion
- Broader longevity formulary (rapamycin, NAD+, sermorelin)
- LegitScript Certified badge now displayed on product pages

Graded #304 · C
Strengths
- Compounded GLP-1 sourced from FDA-registered 503B outsourcing facilities, a stricter standard than the 503A pharmacies many competitors use
- Transparent flat pricing: compounded semaglutide $199/mo (about $171/mo on a 3-month supply) and tirzepatide $299/mo
- Nationwide in all 50 states with free discreet shipping, 24/7 support, and FSA/HSA acceptance
- Multi-vertical menu beyond weight loss (low-dose microdosing, NAD+, sermorelin, metformin) for patients who want bundled wellness care
Where it loses points
- Does not name its specific compounding pharmacy partner, only that it is a 503B facility
- Tirzepatide at $299/mo is mid-market rather than the cheapest option among compounded providers
- Generic corporate branding (Liberty Health) with limited public detail on the operating entity
- Compounded medication only — no brand-name or insurance-covered GLP-1 path
