How much bacteriostatic water to reconstitute Glutathione (1500 mg vial)?
For a 1500 mg Glutathione vial, the volume of bacteriostatic water you add sets the concentration: 3 ml gives 500 mg/ml; 5 ml gives 300 mg/ml; 7.5 ml gives 200 mg/ml; 10 ml gives 150 mg/ml. At the 5 ml reference volume the solution is 300 mg/ml (3 mg per U-100 syringe unit). Research Use Only — these are solution concentrations, not amounts to administer.
| Bacteriostatic water | Concentration | Mass per U-100 unit |
|---|---|---|
| 3 ml | 500 mg/ml | 5 mg |
| 5 ml | 300 mg/ml | 3 mg |
| 7.5 ml | 200 mg/ml | 2 mg |
| 10 ml | 150 mg/ml | 1.5 mg |
Each “mass per U-100 unit” figure is the amount one unit on a U-100 insulin syringe (1 unit = 0.01 ml) holds at that concentration — a property of the prepared solution, not an amount to administer.

How to reconstitute Glutathione
Glutathione is a tripeptide (glutamate–cysteine–glycine) supplied as a 1500 mg lyophilized powder — the largest single-vial mass in the reconstitution range. It therefore takes the widest water volume in the catalog, 3–10 ml. Add bacteriostatic water down the vial wall and swirl gently; do not shake.
With 1500 mg in the vial the concentration stays high across the whole range: 3 ml gives 500 mg/ml, 5 ml gives 300 mg/ml, 7.5 ml gives 200 mg/ml and 10 ml gives 150 mg/ml. The calculator converts whichever volume you pick into a per-syringe-mark mass table.
Glutathione reconstitution — frequently asked questions
How much bacteriostatic water to reconstitute 1500 mg Glutathione?
Between 3 and 10 ml. The large 1500 mg mass is why the volume runs higher than a peptide vial — even 10 ml still yields a concentrated 150 mg/ml solution. Your chosen volume sets the concentration.
What concentration does a 1500 mg Glutathione vial give?
1500 divided by the water millilitres: from 500 mg/ml at 3 ml to 150 mg/ml at 10 ml. The wide preset range (3, 5, 7.5, 10 ml) exists because the vial mass is large.
Why does Glutathione use more water than the peptides?
Concentration is mass over volume, and at 1500 mg the mass is roughly two orders of magnitude above a milligram-scale peptide vial. Spreading it across 3–10 ml keeps the solution workable rather than saturated.
How is reconstituted Glutathione stored?
Refrigerate at 2–8°C and protect from light; store the sealed lyophilized vial at −20°C. Glutathione is light-sensitive, so keep it shielded once in solution.
