NAD+ Injections — Vendors, Pricing & COA Quality

NAD+ (nicotinamide adenine dinucleotide) sold as research-grade lyophilized powder in 500mg and 1000mg vials, plus the smaller patient-ready compounded segment. Live trust grades for active vendors, dosing context, and what to check on a real Certificate of Analysis.

Regulatory context

Injectable NAD+ is not FDA-approved for any indication. Research-grade product is sold as a research chemical under “not for human consumption” labels. Compounded patient-ready NAD+ via licensed pharmacies under physician prescription is the formally legal injection route. This page is research-context only and not medical advice.

Frequently asked questions

What are NAD+ injections?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme involved in cellular energy metabolism and DNA repair. Injected NAD+ — subcutaneous or intramuscular — is used in research and grey-market longevity protocols to raise systemic NAD+ levels more directly than oral NAD precursors (NR, NMN), which face first-pass metabolism. Most research-grade product is lyophilized powder reconstituted with bacteriostatic water at the point of use.

What vial sizes are available?

Research peptide vendors typically sell NAD+ in 500mg and 1000mg lyophilized vials. Compounded patient-ready preparations (where available through licensed compounders) are sometimes 100mg/mL pre-mixed pens. The 500mg and 1000mg dry-powder vials are the dominant SKUs in the Disclosed Labs index in 2026.

How is NAD+ typically dosed?

There is no established standard dose for subcutaneous NAD+ — it is not FDA-approved for any indication and published clinical trial data for the subcutaneous form is limited. Reported grey-market protocols vary widely. Disclosed Labs does not publish specific dosing recommendations; consult a licensed clinician familiar with this category if you are evaluating NAD+ for any use.

What should a quality NAD+ COA include?

Every Certificate of Analysis for an NAD+ product should report at minimum: identity confirmation (HPLC retention-time match against a reference standard, ideally with mass-spec confirmation), HPLC purity %, endotoxin testing (USP <85>), microbial safety (USP <61> or <71>), and net peptide content in mg per vial. Vendors who publish only an HPLC purity number are showing about 20% of the full picture. The Disclosed Labs trust score weights safety panel coverage at 40% specifically because the four non-purity panels are what distinguish a sample that's the right molecule and safe to handle from a sample where you only know the active ingredient percentage.

What are the red flags in an NAD+ vendor?

Patterns the Disclosed Labs corpus surfaces across untrustworthy vendors: (1) NAD+ COAs that reuse lot numbers seen at multiple unrelated 'vendors' (single upstream supplier white-labeled to many resellers), (2) purity values clustered at 99.5–99.8% across every batch (real HPLC variance is wider — narrow clustering suggests rubber-stamping), (3) PDFs whose metadata identifies the source application as Google Sheets, (4) lab signatories with zero LinkedIn or publication footprint, (5) batches whose claimed test dates span months but whose PDF creation timestamps cluster within minutes of each other.

Is NAD+ legal?

NAD+ itself is a naturally-occurring cofactor and is not a scheduled substance. Research-grade NAD+ sold under 'not for human consumption' labels is broadly legal at purchase. Using injectable NAD+ on yourself crosses into a regulatory grey zone the FDA does not currently prosecute end users for but does not endorse. Some compounding pharmacies offer NAD+ IV infusions or subcutaneous injections under physician prescription; that is the formally legal route but is significantly more expensive.

How much do NAD+ injections cost?

Research-grade NAD+ pricing varies by vendor and vial size. The live A/B-grade pricing table above shows the current range as indexed by Disclosed Labs. Compounded patient-ready NAD+ via licensed pharmacies is typically substantially more expensive than research-grade powder, reflecting compounding labor and ready-to-inject formulation costs.
