How the Glutathione concentration calculation works
Concentration is the entered vial amount divided by the resulting solution volume. In this arithmetic example, 600 mg in 6 mL is 100 mg/mL. On a U-100 insulin syringe one unit represents 0.01 mL, so this example has 1,000 mcg per unit. An entered amount of 200 mg therefore corresponds to 200 units.
The tables illustrate conversions, not a treatment schedule. They cannot determine whether a product is approved or suitable for human use. Follow product-specific instructions from your qualified prescriber or pharmacist for preparation, dose, device, and storage.
Glutathione conversion examples (600 mg in 6 mL)
| Dose | Units | mL | Doses per vial |
|---|---|---|---|
| 100 mg | 100 | 1 | 6 |
| 200 mg | 200 | 2 | 3 |
| 400 mg | 400 | 4 | 1 |
Example amounts at 200 mg per dose
| Vial | Water | Concentration | Units per dose | Doses |
|---|---|---|---|---|
| 200 mg | 6 mL | 33.33 mg/mL | 600 | 1 |
| 600 mg | 6 mL | 100 mg/mL | 200 | 3 |
| 1,500 mg | 6 mL | 250 mg/mL | 80 | 7 |
Each amount shows its unit; the form starts in mg. For a fixed amount and dose, doubling the resulting solution volume halves the concentration and doubles the calculated units. The arithmetic number of doses is unchanged. This relationship does not establish an appropriate preparation volume or syringe for a product.
Worked example
600 mg / 6 mL = 100 mg/mL = 100,000 mcg/mL. One unit = 0.01 mL = 1,000 mcg. 200,000 mcg / 1,000 mcg per unit = 200 units. The vial holds 600,000 / 200,000 = 3 doses, which at 3 per week is about 7 days.
See the general peptide reconstitution calculator for the formulas and mg-to-mcg conversions, and our calculator methodology and limitations. The FDA's report on compounded semaglutide dosing errors explains why concentration, units, and measurement instructions need to be confirmed with a health care provider or compounder.
