Glutathione Dosing Calculator & Reconstitution Guide
A tripeptide antioxidant researched for detoxification and skin health.
Glutathione is a research peptide. A tripeptide antioxidant researched for detoxification and skin health. To dose it, reconstitute the vial (for example 600 mg in 3 mL of bacteriostatic water for 200 mg/mL), then divide your target dose by that concentration to find the units to draw.

What is Glutathione?
Glutathione is a tripeptide antioxidant produced naturally in the body. It is studied for its roles in detoxification, immune support, and skin brightening. Research doses are expressed in milligrams and are often relatively large. Also known as GSH.
How many units is each Glutathione dose?
| Dose | Volume to draw | Units (U-100) |
|---|---|---|
| 200 mg | 1 mL | 100 units |
| 600 mg | 3 mL | 300 units |
Based on a 600 mg vial reconstituted with 3 mL of bacteriostatic water (200 mg/mL) and a U-100 insulin syringe. The dose amounts shown are commonly reported by the community and in anecdotal research, not recommendations or medical advice; only the reconstitution math (volume and units) is calculated for you.
How to calculate a Glutathione dose
- 1
Choose your vial and water
Select your Glutathione vial size (for example 600 mg) and the volume of bacteriostatic water you will add (for example 3 mL).
- 2
Find the concentration
Divide vial milligrams by water volume. 600 mg in 3 mL gives 200 mg/mL.
- 3
Calculate the draw
Divide your target dose by the concentration to get the volume in mL, then multiply by 100 to get units on a U-100 insulin syringe.
- 4
Verify on the syringe
Use the Keel calculator to see the exact draw rendered on a to-scale syringe, with a warning if the dose exceeds the syringe capacity.
Glutathione dosing FAQ
How do I reconstitute Glutathione?
A common approach is to add 3 mL of bacteriostatic water to a 600 mg vial, which gives 200 mg/mL. Add the water slowly down the vial wall, swirl gently rather than shaking, and let the powder dissolve fully before drawing.
How many units is 200 mg of Glutathione?
At 200 mg/mL, 200 mg equals 1 mL, which is 100 units on a U-100 insulin syringe.
What Glutathione doses do people report?
Community and anecdotal reports commonly cite 200 to 600 mg. These are figures people report, not a recommendation from Keel. Glutathione is a tripeptide antioxidant produced naturally in the body. It is studied for its roles in detoxification, immune support, and skin brightening. Research doses are expressed in milligrams and are often relatively large.
Which insulin syringe should I use for Glutathione?
A U-100 insulin syringe is standard. A 0.3 mL (30-unit) syringe gives the most precise measurement for small draws, while a 0.5 mL or 1 mL syringe is better when the draw exceeds 30 units. Keel warns you when a dose is larger than the syringe you select.
How should I store Glutathione after reconstitution?
Reconstituted peptides are generally kept refrigerated and protected from light, with the unmixed powder stored cooler still. Follow the guidance from your supplier or a licensed healthcare professional for the specific compound.
What if my Glutathione dose is larger than the syringe holds?
Either use a larger insulin syringe or reconstitute with more bacteriostatic water to lower the concentration, which increases the volume per dose so it fits. Keel flags an over-draw and you can adjust the inputs until the draw fits.
Is Glutathione dosing the same for everyone?
No. The right draw depends on your vial size, how much bacteriostatic water you add, and your target dose. Always recalculate when any of those change, and consult a licensed healthcare professional.
