Defy Medical vs Immortals
The verdict
Immortals takes it — 61.8/100 to 60.2/100, but only just.
Immortals grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. Immortals is a LegitScript-certified longevity telehealth platform founded by Bryan Johnson, offering compounded semaglutide (Semaglutide/Glycine/B12) and tirzepatide (Tirzepatide/Glycine/B12) as microdose… Defy Medical is close behind and may still be the better fit — see the factor split below.
