The Golden Formula
Concentration
CONCENTRATION (mcg/mL) = PEPTIDE (mg) × 1000 ÷ WATER (mL)Units to Draw
UNITS = (DESIRED DOSE ÷ CONCENTRATION) × 100These two formulas work for any peptide. The calculator above applies them automatically.
Quick Reference Tables
5mg Vial
| Water | Concentration | 100 mcg | 250 mcg | 500 mcg |
|---|---|---|---|---|
| 1.0 mL | 5,000 mcg/mL | 2 U | 5 U | 10 U |
| 2.0 mL | 2,500 mcg/mL | 4 U | 10 U | 20 U |
| 2.5 mL | 2,000 mcg/mL | 5 U | 12.5 U | 25 U |
10mg Vial
| Water | Concentration | 250 mcg | 500 mcg | 1 mg |
|---|---|---|---|---|
| 2.0 mL | 5,000 mcg/mL | 5 U | 10 U | 20 U |
| 2.5 mL | 4,000 mcg/mL | 6.25 U | 12.5 U | 25 U |
| 5.0 mL | 2,000 mcg/mL | 12.5 U | 25 U | 50 U |
U-100 Syringe Conversion
On a U-100 insulin syringe, the conversion is simple:
- 100 units = 1 mL
- 50 units = 0.5 mL
- 10 units = 0.1 mL
- 1 unit = 0.01 mL
Pro tip: For doses under 10 units, use a 0.3 mL syringe (30 units max) for better precision — the graduation marks are finer.
