Graded #416 · C
Strengths
- Both compounded semaglutide and tirzepatide available
- Per-dose purchasing — no subscription or membership required

- Broader longevity formulary (rapamycin, NAD+, sermorelin)
- LegitScript Certified badge now displayed on product pages
Where it loses points
- No legal entity name or address disclosed

Graded #250 · C
Strengths
- Available in all 50 states plus DC
- Manage GLP-1, anti-aging peptides, and sexual-health medications on one account
- Offers both compounded semaglutide and compounded tirzepatide
- Independent provider group (Dr Telx) named in the Terms of Service
Where it loses points

- No LegitScript, HIPAA, or NABP accreditation shown on public pages
- Compounding pharmacy not named — only "U.S. pharmacies"
- Terms of Service reads like generic boilerplate, including copy-paste language about women's health issues — suggests low template hygiene
- Delaware governing law for disputes despite a California corporate address
