Glutathione Dosing Calculator
Glutathione: The body's master antioxidant tripeptide.
Pre-filled with the most-reported community reconstitution protocol for Glutathione. See how 1 mL and 2 mL of bacteriostatic water change concentration and syringe-draw volume, then adjust the calculator below for your own vial.
Quick answer · Community-reported standard
A 15 mg vial of Glutathione reconstituted with 2 mL of bacteriostatic water yields a concentration of 7.50 mg/mL. At that concentration, a 600 mg dose of Glutathione equals 8000 units on a U-100 insulin syringe (80.000 mL). Glutathione is typically administered twice weekly via intravenous.
Glutathione reconstitution: 1 mL vs 2 mL bac water
Bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 15 mg vial.
| BAC water added | Concentration | Volume per 600 mg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 15.00 mg/mL | 40.000 mL | 4000 units |
| 2 mL | 7.50 mg/mL | 80.000 mL | 8000 units |

Alternative Glutathione protocols
Beyond the default above, Glutathione is also reported in the following protocols. Use these as starting points and recalculate with the tool above.
Subcutaneous Injection Protocol
Community- Dose
- 200-400 mg
- Frequency
- 2-3 times weekly
- Duration
- 4-8 weeks
- Route
- Subcutaneous
Home-use alternative to IV; uses compounded reduced glutathione
Intramuscular Injection Protocol
Community- Dose
- 200 mg
- Frequency
- 1-2 times weekly
- Duration
- Ongoing
- Route
- Intramuscular
Standard IM glutathione injection; often combined with B-vitamin injections
Nebulized Glutathione Protocol
Community- Dose
- 200-400 mg
- Frequency
- 1-2 times daily
- Duration
- 2-4 weeks
- Route
- Inhalation
Used for respiratory and detoxification purposes; controversial due to potential airway irritation
Antioxidant supplementation (oral)
Clinical- Dose
- 250-500 mg daily in divided doses
- Frequency
- Once or twice daily
- Duration
- 4-12 weeks
Standard oral GSH has low bioavailability; liposomal formulations may improve absorption
Skin lightening (oral/topical combination)
Clinical- Dose
- 500-1200 mg daily oral; 2% topical serum
- Frequency
- Oral twice daily; topical once daily
- Duration
- 8-12 weeks
Combination topical plus oral showed best results in RCTs; effects are modest and may reverse after discontinuation
Glutathione reconstitution & storage
Lyophilized glutathione for injection should be reconstituted with sterile water or bacteriostatic water per manufacturer instructions
Store lyophilized powder at 2-8°C protected from light; reconstituted solution should be used promptly; oral supplements stored at room temperature in airtight containers; include chelators (EDTA) to prevent metal-catalyzed oxidation
Glutathione dosing FAQ
How much bacteriostatic water should I add to a 15 mg vial of Glutathione?
The community standard is 2 mL of bacteriostatic water for a 15 mg Glutathione vial. That gives a concentration of 7.50 mg/mL, so a 600 mg dose is 8000 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 15.00 mg/mL and halves the draw to 4000 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 600 mg dose of Glutathione?
On a standard U-100 insulin syringe, a 600 mg dose of Glutathione is 8000 units when the 15 mg vial is reconstituted with 2 mL of bacteriostatic water (7.50 mg/mL). If you use 1 mL of bac water instead, draw 4000 units (15.00 mg/mL).
What is the standard Glutathione dose?
Community-reported protocols for Glutathione typically use 600 mg–1200 mg twice weekly via Intravenous. 600 mg is a common starting dose. Most common clinical/community protocol; administered as IV push over 10-15 minutes at wellness clinics
Where do you inject Glutathione?
Glutathione is typically injected intravenous. Common sites reported in the literature and by users include: Deltoid (IM), Abdomen (SC), Gluteal (IM). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for Glutathione?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Glutathione because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
