NAD+ is sold in three vial sizes that are one to two orders of magnitude larger than a typical peptide vial. The tables below convert vial mass and solvent volume into concentration — nothing more. Choosing a volume is a measurement decision, not a protocol.
A 1000 mg vial is one hundred times the mass of a 10 mg peptide vial. Volumes that are routine elsewhere in this catalogue produce concentrations here that are not comparable to anything else on the shelf. Work from the label mass in front of you, and read the concentration column rather than reusing a familiar millilitre figure.
| Bacteriostatic water added | Concentration | Contained in 10 units | Contained in 20 units |
|---|---|---|---|
| 1 mL | 100 mg/mL | 10 mg | 20 mg |
| 2 mL | 50 mg/mL | 5 mg | 10 mg |
| 3 mL | 33.3 mg/mL | 3.33 mg | 6.67 mg |
| 5 mL | 20 mg/mL | 2 mg | 4 mg |
| Bacteriostatic water added | Concentration | Contained in 10 units | Contained in 20 units |
|---|---|---|---|
| 1 mL | 500 mg/mL | 50 mg | 100 mg |
| 2 mL | 250 mg/mL | 25 mg | 50 mg |
| 3 mL | 167 mg/mL | 16.7 mg | 33.3 mg |
| 5 mL | 100 mg/mL | 10 mg | 20 mg |
| Bacteriostatic water added | Concentration | Contained in 10 units | Contained in 20 units |
|---|---|---|---|
| 1 mL | 1000 mg/mL | 100 mg | 200 mg |
| 2 mL | 500 mg/mL | 50 mg | 100 mg |
| 3 mL | 333 mg/mL | 33.3 mg | 66.7 mg |
| 5 mL | 200 mg/mL | 20 mg | 40 mg |
Worked example: a 1000 mg vial reconstituted with 2 mL gives 500 mg/mL. Twenty units is 0.2 mL. 0.2 mL × 500 mg/mL = 100 mg.
An insulin syringe is graduated in units, which are a volume marking, not a mass. On both U-100 and U-50 insulin syringes, one unit corresponds to 0.01 mL. The difference is barrel capacity and gradation spacing — not the unit-to-volume relationship. A U-50 holds 0.5 mL across 50 units; a U-100 holds 1.0 mL across 100 units. Both are 100 units per millilitre.
The arithmetic is: mass = (peptide mg ÷ mL of solvent added) × (units × 0.01)
Our reconstitution calculator runs this across a 44-compound library if you would rather not do it by hand.
Sourced fact: The Bacteriostatic Water for Injection label directs: “Do not store reconstituted solutions of drugs for injection unless otherwise directed by the manufacturer of the solute.” The same label describes the product as supplied in “a multiple-dose container from which repeated withdrawals may be made to dilute or dissolve drugs for injection,” preserved with 0.9% or 1.1% benzyl alcohol. [1]
Inference: The widely-quoted 28-day figure describes the multiple-dose container of water, not what you dissolved in it. We traced that rule to its actual source — it is not printed on the FDA label at all — in where the 28-day rule actually comes from.
This is unit-conversion arithmetic for laboratory research planning. It is not medical or veterinary advice, not a protocol, not a recommendation of any volume, and not an instruction to administer anything to any person or animal. NAD+ is not approved by the FDA for human or veterinary use.

BPC-157 is currently the only compound in our catalogue with completed third-party COA figures published on its page — lot 3CDMQXU, chromatographic purity >99.95%, 99.2% of stated label claim, identity confirmed by HPLC-UV-MS, tested by Krause Analytical. Every other product page, including this one, states plainly that its certificate is pending.
