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 is dosed in hundreds of milligrams, usually from a 600 mg vial or a ready-made 200 mg/mL solution. Enter your numbers and see how much of the syringe the dose fills.

About the numbers above

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.

A 600 mg vial at different water volumes

If the draw feels awkward to read, change the water rather than 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 stays in you

Very short in plasma; measured in minutes after intravenous dosing. This site only draws a decay curve where a half-life is actually documented in humans, so there is none here. Treat any precise figure you see elsewhere for Glutathione with suspicion.

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