20 mg Vial — Dose-Volume Table
Concentration is simple division: 20 mg divided by the volume of bacteriostatic water added. The right-hand columns convert each concentration into what a 0.1 mL draw contains and where common research amounts land on a U-100 insulin syringe (1 mL = 100 units).
| BAC water added | Concentration | Per 0.1 mL (10 units) | 1 mg = | 500 mcg = |
|---|---|---|---|---|
| 1 mL | 20 mg/mL | 2 mg (2,000 mcg) | 0.05 mL · 5 units | 0.025 mL · 2.5 units |
| 2 mL | 10 mg/mL | 1 mg (1,000 mcg) | 0.10 mL · 10 units | 0.05 mL · 5 units |
| 3 mL | 6.7 mg/mL | 0.67 mg (670 mcg) | 0.15 mL · 15 units | 0.075 mL · 7.5 units |
| 4 mL | 5 mg/mL | 0.5 mg (500 mcg) | 0.20 mL · 20 units | 0.10 mL · 10 units |
| 5 mL | 4 mg/mL | 0.4 mg (400 mcg) | 0.25 mL · 25 units | 0.125 mL · 12.5 units |
2 mL is the most common choice for a 20 mg vial — round numbers (10 mg/mL; 0.1 mL = 1 mg) reduce measurement error. Volumes above assume the vial holds the added diluent; for research and laboratory use only.
Frequently Asked Questions
how much bac water for 20mg peptide
