small human studies · cited sources
doses of NAD+ used in research
Not an approved drug; the only published human NAD+ infusion study found is a pilot in 8 healthy men who received 750 mg IV over 6 hours. These are the amounts specific labels and studies used, linked to each source. They are references, not recommendations; a prescription label takes priority.

what the numbers mean · where they come from
terms and sources
- Label amount or measured amount. The calculator starts from the amount printed on the vial. A lot certificate’s measured content (net peptide content, in mg) can replace it for the vial that was tested. HPLC purity is a share of peak area, not a mass, so a purity-only correction is shown as an estimate. See HPLC, certificate of analysis and how to read a peptide COA.
- Concentration. Amount in the vial ÷ water added. Terms: reconstitution, bacteriostatic water, lyophilized.
- Syringe units. A volume: 0.01 mL per unit on a U-100 syringe, 0.025 mL on U-40. Units say nothing about the compound until the concentration is known.
- Cost per draw. Vial price × amount per draw ÷ vial amount, from the price per mg of a current offer. Offers come from the NAD+ price comparison; certificates from the COA library.
Arithmetic only, on the numbers entered. Amounts from labels or trials are cited references, not recommendations; PeptideTech does not give personal use instructions and does not test products.
