Master Peptide Reconstitution & Syringe Math Guide
Reconstituting lyophilized peptide powder comes down to three variables: the mass of peptide in the vial (mg), the volume of bacteriostatic water or diluent you add (mL), and the unit scale of your syringe — typically U-100. Every draw on this page is derived from those three numbers.
- 1. Concentration. Divide total vial milligrams by total diluent millilitres: mg ÷ mL = mg/mL. A 10 mg vial mixed with 2 mL of BAC water is 5 mg/mL.
- 2. Dose volume. Divide your target dose by that concentration to get the liquid volume in millilitres: dose ÷ mg/mL = mL. A 2.5 mg dose at 5 mg/mL is 0.5 mL.
- 3. Syringe units. On a U-100 insulin syringe, 1 mL = 100 units, so multiply your millilitres by 100 to land on the exact tick mark: 0.5 mL = 50 units.
Research and educational reference only. Verify every calculation independently — this is not medical advice or a dosing recommendation.

| Vial size | Desired dose | Concentration | Syringe draw | Doses per vial |
|---|---|---|---|---|
| 5 mg | 250 mcg | 2.50 mg/mL | 10.0 units (0.10 mL) | 20 doses |
| 5 mg | 500 mcg | 2.50 mg/mL | 20.0 units (0.20 mL) | 10 doses |
| 10 mg | 2.5 mg | 5.00 mg/mL | 50.0 units (0.50 mL) | 4 doses |
| 10 mg | 5.0 mg | 5.00 mg/mL | 100.0 units (1.00 mL) | 2 doses |
