Peptide Dosage Calculator
Glutathione Dosage Calculator
A free educational Glutathione dosage calculator for research — enter the vial amount and bacteriostatic water volume to get the reconstitution concentration (mg/mL) and syringe-unit reading. Below it, charts convert every Glutathione vial size to mL, cc and U-100 units, and show how much bacteriostatic water each vial takes. Research-use concentration math only; it does not recommend a personal dose, route, or frequency.

How the calculator works
Concentration
peptide ÷ liquid
Total peptide divided by liquid volume gives the concentration per mL.
Volume
target ÷ concentration
The target mass divided by concentration gives the liquid volume.
Syringe units
volume × 100
For insulin units, 100 units equals 1 mL, so mL is multiplied by 100.
Reconstituting Glutathione
Glutathione is studied in antioxidant and detoxification research contexts, supplied as a lyophilized powder. Reconstitution is concentration math: the vial amount and the volume of bacteriostatic water you add set the mg/mL concentration. Enter your vial amount and water volume in the calculator above to compute the concentration and syringe-unit reading.
Glutathione research vials commonly come in 200 mg, 600 mg and larger 1,000-2,000 mg sizes for IV research contexts. Because it is dosed in milligrams, the calculator returns mg/mL concentration and the equivalent insulin-syringe units after you enter the water volume. Glutathione is light- and oxygen-sensitive, so it is typically reconstituted immediately before use; these figures are concentration math, not a personal dose.
Glutathione concentration reference
Resulting concentration (mg/mL) for common Glutathione vial sizes at different bacteriostatic water volumes. This is concentration math for interpreting labels — not a dosing table.
| Vial size | + 1 mL water | + 2 mL water | + 3 mL water |
|---|---|---|---|
| 200 mg | 200 mg/mL | 100 mg/mL | 66.67 mg/mL |
| 600 mg | 600 mg/mL | 300 mg/mL | 200 mg/mL |
| 1000 mg | 1,000 mg/mL | 500 mg/mL | 333.33 mg/mL |
| 1500 mg | 1,500 mg/mL | 750 mg/mL | 500 mg/mL |
| 2000 mg | 2,000 mg/mL | 1,000 mg/mL | 666.67 mg/mL |
Concentration = vial amount ÷ water volume. Use the calculator above for syringe-unit interpretation. Confirm your actual vial label before reconstituting.
Glutathione syringe unit chart (U-100)
A U-100 insulin syringe holds 1 mL across 100 markings, so one unit is always 0.01 mL no matter what is in the vial. That makes the table below a straight conversion between concentration and syringe markings, covering every Glutathione vial size in circulation at each common water volume — it describes what the solution contains, not how much anyone should draw.
| Vial | Water added | Concentration | Per 1 unit | Per 10 units | Full vial |
|---|---|---|---|---|---|
| 200 mg | 1 mL | 200 mg/mL | 2 mg | 20 mg | 100 units |
| 200 mg | 2 mL | 100 mg/mL | 1 mg | 10 mg | 200 units |
| 200 mg | 3 mL | 66.67 mg/mL | 0.67 mg | 6.67 mg | 300 units |
| 600 mg | 1 mL | 600 mg/mL | 6 mg | 60 mg | 100 units |
| 600 mg | 2 mL | 300 mg/mL | 3 mg | 30 mg | 200 units |
| 600 mg | 3 mL | 200 mg/mL | 2 mg | 20 mg | 300 units |
| 1000 mg | 1 mL | 1,000 mg/mL | 10 mg | 100 mg | 100 units |
| 1000 mg | 2 mL | 500 mg/mL | 5 mg | 50 mg | 200 units |
| 1000 mg | 3 mL | 333.33 mg/mL | 3.33 mg | 33.33 mg | 300 units |
| 1500 mg | 1 mL | 1,500 mg/mL | 15 mg | 150 mg | 100 units |
| 1500 mg | 2 mL | 750 mg/mL | 7.5 mg | 75 mg | 200 units |
| 1500 mg | 3 mL | 500 mg/mL | 5 mg | 50 mg | 300 units |
| 2000 mg | 1 mL | 2,000 mg/mL | 20 mg | 200 mg | 100 units |

| 2000 mg | 3 mL | 666.67 mg/mL | 6.67 mg | 66.67 mg | 300 units |
One unit = 0.01 mL · amount per unit = concentration × 0.01. Enter your own vial amount and water volume in the calculator above to convert any other combination. This is educational concentration math, not a dosing chart or a personal dose.
Converting Glutathione to mL, cc and syringe units
Three of the units people meet here are the same measurement written three ways. 1 cc = 1 mL = 100 units on a U-100 syringe, so a figure quoted in cc needs no conversion to mL at all — 0.25 cc is 0.25 mL, which is 25 units. "cc" (cubic centimetre) is the older volume label and still appears on syringe barrels and in a lot of the material circulating about these compounds.
What does need converting is mass to volume, and that is the one step no rule of thumb can shortcut, because it depends entirely on how much bacteriostatic water went into your own vial. Amount ÷ concentration = volume. The table converts amounts across the range a 200 mg Glutathione vial holds, at each water volume.
| Amount | Mixed with 1 mL | Mixed with 2 mL | Mixed with 3 mL |
|---|---|---|---|
| 5 mg | 2.5 units (0.025 mL) | 5 units (0.05 mL) | 7.5 units (0.075 mL) |
| 10 mg | 5 units (0.05 mL) | 10 units (0.1 mL) | 15 units (0.15 mL) |
| 20 mg | 10 units (0.1 mL) | 20 units (0.2 mL) | 30 units (0.3 mL) |
| 50 mg | 25 units (0.25 mL) | 50 units (0.5 mL) | 75 units (0.75 mL) |
| 100 mg | 50 units (0.5 mL) | 100 units (1 mL) | 1.5 mL — over one 1 mL syringe |
The amounts are round reference figures spanning roughly a fiftieth to a half of this vial, chosen so the arithmetic stays in range for this vial size. They are reference points for reading a label, not suggested amounts. Where a row reports more than one syringe, the volume simply exceeds the 1 mL a U-100 barrel holds at that concentration.
How much bacteriostatic water to add to a Glutathione vial
There is no correct answer to this in the sense people usually mean — the water volume is a free choice, and it does not change how much Glutathione you have. It changes only how that fixed amount is spread through the solution, and therefore how many syringe markings any given amount occupies. More water means a weaker solution and a larger, easier-to-read volume; less water means a stronger solution and a smaller one.
Two constraints are worth knowing before choosing. A U-100 syringe reads to about half a unit at best, so a volume that lands under roughly 2 units is hard to measure repeatably; and the same barrel stops at 100 units, so a volume over 1 mL cannot be drawn in one go. Water volumes that put your working amount between those two bounds are the practical range. The round-number volumes below are the ones that produce the tidiest concentration figures for each Glutathione vial size.
| Vial | Water | Concentration | Whole vial measures |
|---|---|---|---|
| 200 mg | 1 mL | 200 mg/mL | 100 units (one full syringe) |
| 200 mg | 2 mL | 100 mg/mL | 200 units (2 full syringes) |
| 200 mg | 3 mL | 66.67 mg/mL | 300 units (3 full syringes) |
| 600 mg | 1 mL | 600 mg/mL | 100 units (one full syringe) |
| 600 mg | 2 mL | 300 mg/mL | 200 units (2 full syringes) |
| 600 mg | 3 mL | 200 mg/mL | 300 units (3 full syringes) |
| 1000 mg | 1 mL | 1,000 mg/mL | 100 units (one full syringe) |
| 1000 mg | 2 mL | 500 mg/mL | 200 units (2 full syringes) |
| 1000 mg | 3 mL | 333.33 mg/mL | 300 units (3 full syringes) |
| 1500 mg | 1 mL | 1,500 mg/mL | 100 units (one full syringe) |

Glutathione is dosed in hundreds of milligrams, so its vials are a different scale from every other compound here
Glutathione is a tripeptide of glutamate, cysteine and glycine, formula C10H17N3O6S, molecular weight 307.3 (PubChem CID 124886), made in every human cell. The injectable form is the reduced one. No glutathione injection is FDA-approved: of 57 DailyMed labels on 2026-09-18, 55 were supplements or cosmetics and two were an eye irrigating solution containing the oxidised form.
That is why its vials run from 200 to 2,000 mg, where most compounds on this site are sold in single-digit milligrams. A compounding pharmacy's product read on 2026-09-18 was a 200 mg/mL solution in 30 mL vials. The highest concentrations in the table below are arithmetic only; they say nothing about whether that much powder dissolves in that little water.
The handling fact specific to this compound is the ingredient grade. The CDC's page dated 2026-09-15 reports more than 25 people ill in at least four states after compounded glutathione made with a dietary-supplement-grade ingredient, at least three of them hospitalised after intravenous use, with fever, chills, low blood pressure and shock consistent with endotoxin exposure.
| Vial | 1 mL water | 2 mL water | 3 mL water |
|---|---|---|---|
| 200 mg | 200 mg/mL | 100 mg/mL | 66.67 mg/mL |
| 600 mg | 600 mg/mL | 300 mg/mL | 200 mg/mL |
| 1,000 mg | 1,000 mg/mL | 500 mg/mL | 333.33 mg/mL |
| 1,500 mg | 1,500 mg/mL | 750 mg/mL | 500 mg/mL |
| 2,000 mg | 2,000 mg/mL | 1,000 mg/mL | 666.67 mg/mL |
The trial doses are infusions, and a syringe reading only fits the smaller figures
The largest indexed intravenous trials used 2,500 mg before angioplasty and again at 24, 48 and 72 hours (Tanzilli et al., BMJ Open 2019 and Journal of the American Heart Association 2021) and 1,400 mg three times a week for four weeks in Parkinson's disease (Hauser et al., Movement Disorders 2009). A registered phase 3 pneumonia trial gives 600 mg in 50 mL of saline twice daily for five days (NCT06296212). Those amounts are diluted and infused, so syringe units describe only how much of a vial is drawn.
Vendor pages read on 2026-09-18 state 100 to 200 mg once daily under the skin and 600 mg into the muscle. On a 1 mL U-100 syringe, at two common set-ups:

FAQ
How often were glutathione injections given in the published studies?
It varies with the study. The Parkinson's trial gave 1,400 mg intravenously three times a week for four weeks (Hauser et al., 2009); the angioplasty trials gave 2,500 mg before the procedure and at 24, 48 and 72 hours (Tanzilli et al., 2019 and 2021); a registered pneumonia trial gives 600 mg twice daily for five days (NCT06296212). A compounding pharmacy's page read on 2026-09-18 cited two to three sessions a week. None of these is an approved schedule, because no glutathione injection is approved.
What concentration does a 1,500 mg glutathione vial give?
With 3 mL of water it is 500 mg/mL, so each U-100 unit is 5 mg and 200 mg is 40 units; with 2 mL it is 750 mg/mL and each unit is 7.5 mg. Whether 1,500 mg fully dissolves in 2 mL is a solubility question the arithmetic does not answer.
Is the Glutathione dosage calculator a personal dosing tool?
No. "Dosage calculator" is the common search term, but this is an educational reconstitution and concentration-math tool: it converts vial amount, bacteriostatic water volume, and syringe capacity into concentration (mg/mL) and unit readings. It does not provide a personal dose, route, frequency, or treatment guidance.
How do I reconstitute Glutathione?
Add bacteriostatic water gently down the vial wall and swirl (never shake) until clear. The water volume and the vial amount together set the concentration; the calculator above computes the mg/mL and the syringe-unit reading. This is research concentration math only.
What concentration does a 200 mg Glutathione vial give?
200 mg reconstituted with 1 mL of bacteriostatic water is 200 mg/mL; with 2 mL it is 100 mg/mL; with 3 mL it is 66.67 mg/mL. Enter your actual vial amount and water volume above to see the concentration and per-unit reading.
How many units on an insulin syringe is a 200 mg Glutathione vial?
A U-100 insulin syringe holds 1 mL across 100 units, so one unit is always 0.01 mL. A 200 mg Glutathione vial reconstituted with 1 mL of bacteriostatic water is 200 mg/mL, so each unit contains 2 mg and 10 units contain 20 mg; the whole vial is 100 units. Add 2 mL instead and each unit contains 1 mg across 200 units. This is a conversion between concentration and syringe markings, not a dose.
How do I convert Glutathione mg to mL?
Divide the amount by the concentration. With a 200 mg vial in 1 mL of bacteriostatic water (200 mg/mL), 1 mg occupies 0.005 mL, which is 0.5 units on a U-100 syringe. Using more water lowers the concentration, so the same amount occupies proportionally more volume — the unit chart above shows this for each water volume.
How many cc is a Glutathione draw?
1 cc and 1 mL are the same volume, and on a U-100 syringe both equal 100 units — so a figure quoted in cc needs no conversion, only a decimal shift to units. 0.1 cc is 0.1 mL is 10 units; 0.25 cc is 25 units. "cc" is the older label and still appears on syringe barrels. What that volume contains depends on your concentration: at 200 mg/mL (a 200 mg vial in 1 mL), 10 units holds 20 mg.
How much bacteriostatic water should I add to a 200 mg Glutathione vial?
The volume is a free choice and does not change how much Glutathione is in the vial — only how far it is spread, and therefore how many syringe markings a given amount occupies. 1 mL gives 200 mg/mL, 2 mL gives 100 mg/mL, 3 mL gives 66.67 mg/mL. Two practical bounds apply: a U-100 syringe reads to roughly half a unit, so volumes under about 2 units are hard to measure repeatably, and the barrel stops at 100 units, so anything over 1 mL cannot be drawn in one pass.
Does using more bacteriostatic water make Glutathione weaker?
It makes the solution less concentrated, not the vial contents smaller. A 200 mg vial holds 200 mg whether it is dissolved in 1 mL or 3 mL — the same total spread through more liquid, so any given amount is carried in a proportionally larger volume. Doubling the water halves the concentration and doubles the units that the same amount measures as.
Do I recalculate Glutathione if my vial is a different size?
Yes, and this is the most common arithmetic error with these compounds. Concentration is vial amount ÷ water volume, so a unit figure worked out for one vial size is wrong for another even with identical water. Glutathione circulates in 200 mg, 600 mg, 1000 mg, 1500 mg, 2000 mg vials, and the tables above give each one separately. Enter your own label figures in the calculator rather than reusing a number quoted for someone else's vial.
Does Medibact sell Glutathione?
Medibact publishes a Glutathione research guide and supplies the USP-grade bacteriostatic water used to reconstitute lyophilized peptides — it does not sell the peptide itself, and neither does this site.
