The short answer
Mixed with 10 mL of bacteriostatic water, a 1,500 mg vial of Glutathione holds 150 mg/mL. A 200 mg dose is then 1.33 mL on a U-100 insulin syringe, and the vial holds about 7 doses of that size. Taken 3× per week, it lasts about 2.5 weeks.
How much water
The water only sets the strength; the dose and the number of doses in the vial stay the same. Draws are on a U-100 insulin syringe, where 1 unit is 0.01 mL.
| Water added | Strength | Per syringe unit | Draw for 200 mg |
|---|---|---|---|
| 3 mL | 500 mg/mL | 5 mg | 40 units (0.40 mL) |
| 5 mL | 300 mg/mL | 3 mg | 66.7 units (0.67 mL) |
| 10 mL | 150 mg/mL | 1.5 mg | 1.33 mL |

Draws over 100 units show in mL. Faded values are under 2 units, which is hard to measure. Check that your vial holds the larger volumes.
Where the doses come from
- Label 600 mg IM or slow IV for ongoing therapy; about 2.5 g IV before each cisplatin dose.
- Community 200–600 mg IM or SC, 2–3× per week. IV 600–1,200 mg weekly to every 2 weeks.
Doses are what labels, trials or community reports reference, not recommendations. Glutathione’s page has the cycle, side effects, cautions and sources.
Mixing and storage
- PrepareLet a refrigerated vial come to room temperature, and wipe both stoppers with an alcohol swab.
- Add 10 mLDraw 10 mL of bacteriostatic water and let it run slowly down the inside wall of the vial.
- Swirl, don’t shakeSwirl gently until the powder dissolves and the liquid is clear.
- Label itWrite the date and the strength, 150 mg/mL, on the vial.

Questions
How much water do I add to a 1,500 mg vial of glutathione?
There’s no single right amount: the water only sets the strength. With 10 mL of bacteriostatic water, a 1,500 mg vial holds 150 mg/mL. With 3 mL it’s 500 mg/mL; with 5 mL it’s 300 mg/mL. Less liquid makes each dose a smaller draw; more makes small doses easier to measure.
How many units is 200 mg of glutathione?
With 10 mL in a 1,500 mg vial, 200 mg is 1.33 mL on a U-100 insulin syringe. With 3 mL, 40 units (0.40 mL); with 5 mL, 66.7 units (0.67 mL).
How many doses are in a 1,500 mg vial of glutathione?
About 7 doses of 200 mg, or 3 of 500 mg or 2 of 600 mg. Taken 3× per week at 200 mg, it lasts about 2.5 weeks.
How long does a mixed vial of glutathione keep?
Powder: −20 °C, protected from light. Mixed: use within 8 hours (label).
