Use this glutathione calculator to convert vial strength and BAC water volume into a precise draw. Glutathione is dosed in the hundreds of milligrams, so volumes are larger than most peptides; this page covers the math only.
- Common vial examples
- 600 / 1200 mg
- Example dose
- 200 mg
- Common syringe
- U-100 insulin
- Last reviewed
Storage before and after reconstitution: Lyophilised 2–8°C; reconstituted vial refrigerated and protected from light.
Quick answers: Glutathione doses in units
With a 600 mg vial mixed with 3 mL of bacteriostatic water (200 mg/mL), on a U-100 insulin syringe:
- How many units is 200 mg of glutathione?
- 100 units (1 mL)
- How many units is 600 mg of glutathione?
- 300 units (3 mL), more than one 1 mL syringe
Educational maths only, not a dose recommendation. Use the calculator above for your own vial, water volume and syringe.
Quick math example
A 600 mg vial mixed with 3 mL gives 200 mg/mL. A 200 mg dose is 1.0 mL, which equals 100 units on a U-100 syringe.
Glutathione reconstitution reference
U-100 units to draw for each common Glutathione dose, by vial size, reconstituted with 3 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 200 mg | 600 mg |
|---|---|---|---|
| 600 mg | 200 mg/mL | 100 u(1 mL) | 300 u(3 mL) |
| 1200 mg | 400 mg/mL | 50 u(0.5 mL) | 150 u(1.5 mL) |

Educational reference only — not a dose recommendation. Units assume a U-100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
How the glutathione calculation works
Glutathione vials are large — often 600 mg or more — and doses are in the hundreds of milligrams. Concentration is the vial mg divided by water volume; the draw is your target dose divided by that concentration.
- 600 mg vial in 3 mL = 200 mg/mL
- 200 mg / 200 mg per mL = 1.0 mL
- 1.0 mL = 100 units on a U-100 syringe
Glutathione 600 mg vial with 3 mL example
A 600 mg glutathione vial mixed with 3 mL gives 200 mg/mL.
A 200 mg dose is 1.0 mL — a full 100-unit U-100 syringe. A 600 mg dose is 3.0 mL, which exceeds a 1 mL insulin syringe, so larger doses are drawn into a bigger syringe or given as a slow injection.
- 600 mg / 3 mL = 200 mg/mL
- 200 mg = 1.0 mL = 100 units
- 600 mg = 3.0 mL — larger than a 1 mL syringe
Large-volume doses
Because glutathione doses are large, a single dose can exceed a standard insulin syringe. Some people split the dose or use a larger syringe. Use more bacteriostatic water only if you want a lower concentration; it will increase the volume drawn.
- Doses often exceed 1 mL — plan your syringe accordingly
- Higher concentration (less water) shrinks the volume
- Confirm route and dose with your protocol
