How many units is 200 mg of Glutathione?

It depends entirely on how much water you added. In a 600 mg vial reconstituted with 3 mL, the concentration is 200 mg/mL, so 200 mg is 1 mL, which is 100 units on a U-100 insulin syringe. In the same vial with 1.5 mL of water it is 50 units, and with 4.5 mL it is 150 units.

How much bacteriostatic water for a 600 mg Glutathione vial?

3 mL is the usual choice. It gives 200 mg/mL, which puts the commonly reported range of 100 mg to 600 mg between roughly 50 and 300 units. Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.

How many doses are in a 600 mg vial?

Divide 600 by your dose. At 200 mg that is 3 doses, which at three times a week is 7 days.

How many units is 200 mg of glutathione?

At 200 mg/mL, which is a 600 mg vial in 3 mL, 200 mg is 1 mL, or 100 units, a full syringe. Larger doses need a larger syringe or a second injection.

Glutathione dosage calculator

Glutathione is dosed in hundreds of milligrams, usually from a 600 mg vial or a ready-made 200 mg/mL solution, so the dose fills much of the syringe.

About Glutathione

Glutathione is a tripeptide (glutamate, cysteine, glycine) and the body's main intracellular antioxidant. Injectable glutathione is widely used in clinics, usually intravenously, and is also sold as a lyophilised powder or a pre-made 200 mg/mL solution for subcutaneous or intramuscular use. It is not an approved injectable medicine for general use.

The doses are large. A 600 mg vial with 3 mL of water is 200 mg/mL, so 200 mg is 1 mL, a full insulin syringe. If your vial came already in solution at 200 mg/mL, enter 600 mg and 3 mL to describe it, or whatever the label states. Reported doses are 200 to 600 mg, two or three times a week.

The same 600 mg vial at other water volumes

If the draw is awkward to read, change the water, not the dose. The dose stays the same; only the mark moves.

Vial	BAC water	Concentration	Draw	U-100 units	Doses/vial
600 mg	2 mL	300 mg/mL	0.667 mL	66.7 units	3
600 mg	3 mL	200 mg/mL	1 mL	100 units	3
600 mg	5 mL	120 mg/mL	1.667 mL	166.7 units	3
1500 mg	2 mL	750 mg/mL	0.267 mL	26.7 units	7
1500 mg	3 mL	500 mg/mL	0.4 mL	40 units	7
1500 mg	5 mL	300 mg/mL	0.667 mL	66.7 units	7

All rows above assume a 200 mg dose and a standard U-100 insulin syringe, where 100 units = 1 mL.

How long it lasts in the body

Very short in plasma; measured in minutes after intravenous dosing. A decay curve is only drawn where a human half-life is documented, so there is none here. Treat any precise figure for Glutathione elsewhere with caution.

Before you use these numbers This is a unit-conversion tool. It turns a vial strength and a water volume into a concentration, a draw volume and a syringe mark. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most compounds listed are sold for laboratory research and are not approved for human use. Nothing here is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always check the strength printed on your own vial rather than trusting a preset.
