Technically no — it's a dinucleotide coenzyme. We include it because reconstitution and dosing math is similar to peptide protocols.

Key takeaways

At the reference preset of a 500mg NAD+ vial reconstituted with 5 mL of bacteriostatic water, a 100mg dose measures 100 units on a U-100 insulin syringe.

NAD+ is a coenzyme present in every living cell, central to mitochondrial energy metabolism and sirtuin activation.

About

What is NAD+?

NAD+ is a coenzyme present in every living cell, central to mitochondrial energy metabolism and sirtuin activation. Subcutaneous and intravenous protocols are used in compounding-pharmacy practice for energy, recovery, and longevity-adjacent endpoints. It is not, strictly speaking, a peptide — but it is widely included in peptide-injection protocols and reconstitution math is similar.

Common vial sizes

100 mg	lyophilized powder
500 mg	lyophilized powder
1000 mg	lyophilized powder

Reference dose ranges

50 mg	≈ 50 U-100 units (at 500mg / 5mL)
100 mg	≈ 100 U-100 units (at 500mg / 5mL)
200 mg	≈ 200 U-100 units (at 500mg / 5mL)
500 mg	≈ 500 U-100 units (at 500mg / 5mL)

Reconstitution

How it's typically prepared

Reconstitute with BAC water; refrigerate. NAD+ subcutaneous injections can be locally painful; topical anaesthetic or split injections are sometimes used.
