— What to expect
A typical course of NAD+ Injection.
— The science
How NAD+ Injection works, and what the research shows.
— How it works
NAD+ injections deliver nicotinamide adenine dinucleotide directly into circulation, bypassing oral bioavailability issues.
NAD+ is essential for sirtuin activation, DNA repair, and cellular energy metabolism — all of which decline with age.
— Clinical evidence
NAD+ levels decline significantly with age, falling 50-70% by the seventh decade.
Massudi et al., PLOS ONE 2012This decline is implicated in mitochondrial dysfunction, impaired DNA repair, and accelerated cellular senescence.
Yoshino et al. demonstrated that NMN supplementation restored mitochondrial function in aged mice.
Cell Metab 2018Direct NAD+ injection achieves substantially higher peak serum levels than oral precursors (NR, NMN) and bypasses first-pass metabolism.
Clinical studies are emerging, with ongoing trials in cardiovascular disease, neurodegeneration, and aging biomarkers.
NAD+ replacement is now considered a foundational longevity-medicine intervention.

NAD+ Injection is $249 per month at Pepti as a vial, or $319 as a pre-filled pepti Pen. That is all-in: medication, physician review and ongoing care, shipping, and messaging. No membership, consult, or visit fees, and the price is the same in every state.
NAD+ Injection is commonly prescribed for: Adults focused on energy, mental clarity, and cellular repair; Patients who want injectable NAD+ rather than an IV visit. Whether it is appropriate for you is decided by the reviewing physician from your history, medications, and labs where required.
Yes. NAD+ Injection is prescription-only. The free online assessment takes about five minutes, a physician licensed in your state reviews it within 24 hours, and if approved the prescription goes to the pharmacy. If not approved, the medication charge is refunded.
No. NAD+ Injection can be prescribed from the assessment alone. Bloodwork is required only for the GLP-1s and growth-hormone secretagogues, and the intake tells you if a medication on your order needs it.
NAD+ Injection is a subcutaneous injection into the abdomen or thigh with a small insulin syringe. Your kit ships with sterile syringes and alcohol prep pads, and the exact dose and schedule are printed on the pharmacy label. Dosing videos are in your account. It is also available as a pre-filled pepti Pen for $319.

The physician screens your history, medications, and allergies before prescribing, the medication-specific consent lists the known risks, and you can message your physician about anything you notice. Seek emergency care for severe symptoms.
