Best for injectable NAD+ (telehealth)
Marek Health is one of the most-referenced telehealth platforms for injectable NAD+. Their programs include physician oversight, lab-compounded injectable NAD+, and shipping — starting in the $100–$150/month range depending on dose and protocol.
Defy Medical similarly offers injectable NAD+ as part of their optimization menu, with pricing in the same range. Both platforms require a consultation and basic labs before prescribing.
For men and women who want ongoing NAD+ maintenance without clinic visits, these telehealth injection programs represent the best cost-to-convenience ratio.
