Calculators / PT-141 dose charts
PT-141 dose charts (mg → U-100 units)
Units to draw on a standard U-100 insulin syringe, for each common PT-141 vial size and BAC-water volume. Doses shown reflect ranges reported in published research — they are reference points for the math, not recommendations. For other numbers, use the live calculator.
10 mg vial
| Dose | + 1 mL water (10 mg/mL) | + 2 mL water (5 mg/mL) | + 3 mL water (3.3333333333333335 mg/mL) |
|---|---|---|---|
| 500 mcg | 5 u | 10 u | 15 u |
| 1 mg | 10 u | 20 u | 30 u |
| 1.5 mg | 15 u | 30 u | 45 u |
| 2 mg | 20 u | 40 u | 60 u |
Formula: units = dose ÷ concentration × 100 · concentration = vial mg ÷ water mL · PT-141 half-life ≈ 2.7 h (FDA VYLEESI (bremelanotide) label, NDA 210557 (2019); plasma half-life ≈ 2.7 h)
