FOXO4-DRI is sold in a single 10 mg vial size. The tables below convert vial mass and solvent volume into concentration — nothing more. Choosing a volume is a measurement decision, not a protocol.
Where a catalogue offers one size, it is tempting to work from memory or from the email receipt. Read the printed label on the vial in front of you before adding anything. Vial specifications change, orders get substituted, and lyophilised powder gives no visual clue about its mass. The label is the only input this calculation has, so it is the only thing worth double-checking.
| Bacteriostatic water added | Concentration | Contained in 10 units | Contained in 20 units |
|---|---|---|---|
| 1 mL | 10 mg/mL | 1 mg | 2 mg |
| 2 mL | 5 mg/mL | 0.5 mg | 1 mg |
| 3 mL | 3.33 mg/mL | 0.333 mg | 0.667 mg |
| 5 mL | 2 mg/mL | 0.2 mg | 0.4 mg |
Worked example: a 10 mg vial reconstituted with 2 mL gives 5 mg/mL. Twenty units is 0.2 mL. 0.2 mL × 5 mg/mL = 1 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. FOXO4-DRI 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.
