The verdict

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 per-dose or monthly pricing published — only a "$199 to get started" hook; you can't compare costs before intake
- 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
Graded #106 · C
Strengths
- Flat $199/mo program bundles consult, medication and overnight shipping
- Brand-name semaglutide and Zepbound vials, not just compounded
- Serves all 50 states, fully online
- LegitScript certified with US-based, state-licensed providers
- Backed by parent company LifeMD
Where it loses points
- Does not accept insurance
- Marketed primarily to men via a men's-health platform
- Zepbound vial cost rises with dose titration
- Branded-only program costs more than compounded options
