How Do You Dose Peptides?
⚡ Direct Answer
Calculate peptide dosing using the formula: Draw Units = (Target Dose in mg ÷ Concentration in mg/mL) × 100. For example, if a 5mg vial reconstituted with 2.0 mL water has a concentration of 2.5 mg/mL, a 250 mcg (0.25 mg) target dose requires: (0.25 ÷ 2.5) × 100 = 10 units on a U-100 syringe.
Standard Peptide Dosing Calculation Examples
Vial Size:2 mg
Bac Water:1.0 mL
Concentration:2.0 mg/mL
Target Dose:100 mcg (0.10 mg)
U-100 Syringe Draw:5 Units (0.05 mL)
Vial Size:5 mg
Bac Water:2.0 mL
Concentration:2.5 mg/mL
Target Dose:250 mcg (0.25 mg)
U-100 Syringe Draw:10 Units (0.10 mL)
Vial Size:10 mg
Bac Water:2.0 mL
Concentration:5.0 mg/mL
Target Dose:500 mcg (0.50 mg)
U-100 Syringe Draw:10 Units (0.10 mL)
Vial Size:10 mg
Bac Water:2.0 mL
Concentration:5.0 mg/mL
Target Dose:1,000 mcg (1.00 mg)
U-100 Syringe Draw:20 Units (0.20 mL)
| Vial Size | Bac Water | Concentration | Target Dose | U-100 Syringe Draw |
|---|---|---|---|---|
| 2 mg | 1.0 mL | 2.0 mg/mL | 100 mcg (0.10 mg) | 5 Units (0.05 mL) |
| 5 mg | 2.0 mL | 2.5 mg/mL | 250 mcg (0.25 mg) | 10 Units (0.10 mL) |
| 10 mg | 2.0 mL | 5.0 mg/mL | 500 mcg (0.50 mg) | 10 Units (0.10 mL) |
| 10 mg | 2.0 mL | 5.0 mg/mL | 1,000 mcg (1.00 mg) | 20 Units (0.20 mL) |
