Immortals vs KERNX Health
The verdict
KERNX Health takes it — 62.2/100 to 61.8/100, but only just.
KERNX Health grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. Washington DC telehealth platform selling compounded semaglutide and tirzepatide on flat monthly plans, with the physician consultation billed separately per visit. Immortals is close behind and may still be the better fit — see the factor split below.

Graded #284 · 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 #276 · C
Strengths
- Publishes plan pricing openly, before any intake or account creation
- Month-to-month with no long-term contract and no multi-month prepayment
- Billing starts only after a licensed provider approves treatment
- LegitScript certification verified against the issued seal, not just the badge
Where it loses points
- Its own pricing page contradicts itself: it claims no separate consultation charges, then states a $25-$60 fee applies per visit
- The consultation fee is charged whether or not a prescription is issued
- Advertised $129 and $199 rates are time-limited founding rates; standard rates are $249 and $299
- No compounding pharmacy is named anywhere on the site
- Shipping claims conflict: a 48-hour figure on the homepage against 1-2 days to ship plus 2-3 days transit in the FAQ
