Immortals vs StackMD
The verdict
StackMD takes it — 63.4/100 to 61.8/100, but only just.
StackMD grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. StackMD is a New York telehealth platform (Medical 360 HC PLLC) selling compounded semaglutide and tirzepatide, both formulated with B12 and glycine, alongside NAD+, sermorelin and other longevity peptides. Immortals is close behind and may still be the better fit — see the factor split below.

Graded #286 · C
Strengths
- LegitScript certified (ID 50458743) with board-certified U.S. physician review within 72 hours
- Physician consult + prescription bundled in price — 'You pay for treatment. That's it' with no added fees
- Competitive pricing: semaglutide microdose from $167/month, tirzepatide from $180/month (promotional)
- Unlimited provider messaging for 12 months included; video consults available
- Founded by Bryan Johnson and Kate Tolo; clinical lead Dr. Carl Seger, M.D. (preventive/longevity medicine)
Where it loses points
- Microdose framing uses sub-clinical doses — lower weight-loss efficacy than standard GLP-1 protocols
- Quarterly commitment only — 3-month minimum, paid upfront ($501–$540/quarter); no monthly flexibility
- State availability not publicly listed; 'eligible U.S. states' with no specific state list
- Labs not included; baseline bloodwork protocol not disclosed on any public page
- Compounding pharmacy not named; no 503A/503B accreditation details disclosed
Graded #259 · C
Strengths
- Publishes an exact price for every dose strength rather than a single 'from' figure — semaglutide $125-$225, tirzepatide $199-$449
- Names both its legal entity (Medical 360 HC PLLC) and its prescribing telehealth partner, SamaritanMD
- No membership or platform fee — the medication price is the whole price
- States plainly that its compounded medications are 'not FDA-approved and have not been evaluated by the FDA for safety, efficacy, or quality'
- Telehealth offered in all 50 states per its terms, with free discreet shipping and FSA/HSA eligibility
Where it loses points
- All sales are final — 'No refunds are issued except as described below', and dispensed medication cannot be returned
- Compounding pharmacies are never named, only 'a licensed third-party pharmacy'
- Price rises steeply with dose: tirzepatide runs $199 at 5mg to $449 at 30mg
- Billing and refunds are handled by SamaritanMD — StackMD 'has no authority to issue refunds' on its behalf
- Terms impose binding arbitration in New York and waive jury trial and class-action participation
