Calculators / HCG dose charts
HCG dose charts (mg → U-100 units)
Units to draw on a standard U-100 insulin syringe, for each common HCG 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.
5 mg vial
| Dose | + 1 mL water (5 mg/mL) | + 2 mL water (2.5 mg/mL) | + 3 mL water (1.6666666666666667 mg/mL) |
|---|---|---|---|
| 250 mcg | 5 u | 10 u | 15 u |
| 500 mcg | 10 u | 20 u | 30 u |
| 1 mg | 20 u | 40 u | 60 u |
10 mg vial
| Dose | + 1 mL water (10 mg/mL) | + 2 mL water (5 mg/mL) | + 3 mL water (3.3333333333333335 mg/mL) |
|---|---|---|---|
| 250 mcg | 2.5 u | 5 u | 7.5 u |
| 500 mcg | 5 u | 10 u | 15 u |
| 1 mg | 10 u | 20 u | 30 u |
Formula: units = dose ÷ concentration × 100 · concentration = vial mg ÷ water mL · HCG half-life ≈ 33 h (hCG pharmacokinetic literature (see monograph))
