What is Glutathione?
Glutathione (GSH, γ-glutamyl-cysteinyl-glycine) is a tripeptide — it consists of three amino acids (glutamate, cysteine, glycine). It is produced naturally in almost every cell and is regarded as the body’s “master antioxidant”, with a central role in protecting cells from oxidative stress.
Its functional key is the thiol (-SH) of cysteine: this group neutralises free radicals and maintains the cell’s redox (oxidation–reduction) balance. Glutathione alternates between its reduced (GSH) and oxidised (GSSG) form — the GSH/GSSG ratio is a key indicator of cell health.
It is studied for antioxidant protection, detoxification (it takes part in the liver’s phase II reactions), immune support and general cell health. It works in a complementary way with other energy/redox systems such as NAD+. See the range in the all products category.
In the Peptology version, it is supplied as a lyophilised research-grade powder with purity > 99%, in a 1500 mg format. It is intended exclusively for scientific, research and in vitro applications — it is not a medicine or a supplement in this form.

How Glutathione works — redox balance
RADICAL NEUTRALISATION
The thiol (-SH) donates electrons to neutralise free radicals and peroxides, protecting lipids, proteins and DNA.
GSH ↔ GSSG CYCLE
After it acts, the oxidised form (GSSG) is regenerated into the reduced form (GSH) via reductase — a continuous, renewable cycle.
DETOXIFICATION
It takes part in the liver’s phase II conjugation reactions, making toxins and xenobiotics water-soluble for removal.
A small tripeptide, a big role
Despite its small size (just three amino acids), glutathione is the most abundant intracellular antioxidant. The GSH/GSSG ratio acts as a “barometer” of oxidative stress: a drop in it is linked with ageing and cell damage, while maintaining it is a central goal of cell-health research.
Its antioxidant action is linked with other systems: NAD+ supports the regeneration enzymes, while mitochondrial antioxidants such as SS-31 act specifically on the mitochondria. The mechanisms come from clinical and preclinical studies.

Research
Oxidative stress and cell protection
Glutathione is one of the most studied intracellular antioxidants. Maintaining adequate GSH levels and a healthy GSH/GSSG ratio is linked with protection from oxidative stress across a broad range of cell models.
Detoxification and liver function
Through its participation in phase II conjugation reactions, glutathione is central to the liver’s detoxification of xenobiotics and is investigated in related protection models.
Data limitations
The bioavailability of exogenous glutathione depends on the route of administration — an active field of research. This particular form is offered as a research product, not approved for clinical use.
Note: Scientific reference based on clinical/preclinical data. It is not medical advice or a claim for the product.
In brief — scientific profile
- Tripeptide (glutamate–cysteine–glycine) — the “master antioxidant”
- Neutralises free radicals — via the thiol (-SH)
- Maintains redox balance — GSH ↔ GSSG cycle
- Central to detoxification — liver phase II reactions
- Works with NAD+ and mitochondrial antioxidants — cell health
- Research product — not approved in this form
Side effects and safety
Glutathione, as a natural endogenous molecule, is generally considered well tolerated. The reactions reported are mostly mild.
Common
- Injection-site reactions
- Mild gastrointestinal discomfort
- Transient headache
Less common
- Dizziness
- Transient rash
- Sensation of a “sulphurous” smell/taste
Precautions
- Allergic reaction / hypersensitivity
- Caution in asthma (reports of bronchospasm)
- Limited data on long-term use
Rare bronchospasm reactions have been reported in sensitive individuals; which is why there is a precaution in asthma. Scientific reference, not instructions for use.

Glutathione 1500 mg: which strength
Glutathione is available in: 1500 mg.
Research protocols
Important: Reference information for research purposes — not a recommendation for use or medical advice.
In the research literature, glutathione schedules take the issue of bioavailability into account:
- The route of administration significantly affects the availability of exogenous glutathione
- It is often studied in cycles, with oxidative stress markers for monitoring
- It is investigated in combination with cysteine precursors or NAD+ systems for synergy
The schedules come from the research literature and do not constitute a recommendation for individual use.
Storage and reconstitution
It is supplied as a lyophilised powder in a 1500 mg vial. Lyophilised, it is stable at room temperature, away from light/humidity. Glutathione oxidises easily in solution, so reconstitution is done shortly before use. The recommended solvent is Peptide Matrix Water™, which significantly extends the shelf life of the solution.
- Before reconstitution: room temperature, away from light/moisture; up to 24 months.
- With Peptide Matrix Water™ (recommended): refrigerator 2–8 °C, dark container, up to 60 days.
- With bacteriostatic water or sterile water: refrigerator 2–8 °C up to 28 days, away from light.
- Reconstitution: add the solvent slowly down the wall of the vial, without vigorous agitation; use soon after.
Laboratory tip: Add Peptide Matrix Water™ to your basket — the recommended stabilising solvent for all reconstituted products.
Laboratory protocol — reconstitution, research protocols, storage
Standard protocol, applicable to all research peptides in the Peptology catalogue. For the concentration of the solution (mg/mL) per vial, use the peptide reconstitution calculator.
The 60-second protocol
1. SOLVENT
2. RECONSTITUTION
The solvent is added to the wall of the vial, without agitation, then wait 10–15 minutes.
3. CALCULATION
Calculator → concentration in mg/mL
4. STORAGE
+2 °C to +8 °C, up to 60 days with Peptide Matrix Water
Quick reference
| Parameter | Value |
|---|---|
| Form | Lyophilised powder |
| Solvent | Peptide Matrix Water |
| Volume for reconstitution | 1–3 mL — 3 mL maximum (capacity of the standard vial) |
| Storage before reconstitution | Room temperature, protected from direct light (refrigeration is not mandatory) |

What you will need
Precision pipette
Calibrated, 100–1000 µL — for accurate measurement of the volume of solvent added to the vial.
70% alcohol pads
Two pads — to disinfect the peptide vial and the solvent vial.
Stabilised solvent for lyophilised peptides. Why this one.
Five rules for reconstitution
| ✅ Correct | ❌ Wrong |
|---|---|
| Disinfect the stoppers and the work surface with 70% alcohol, work with gloves | Working without disinfection |
| The solvent is added slowly down the wall of the vial | Direct jet onto the powder — foaming and denaturation |
| Light swirling between the palms | Shaking — foam, on which the peptides denature |
| Wait 10–15 minutes at room temperature | Mechanical mixing or heating |
| Visual inspection: clear, without particles | Using a cloudy or coloured solution |
Calculating the concentration
⚠️ Maximum 3 mL of solvent. The standard vial does not allow a larger volume — do not exceed it during reconstitution.
- Concentration (mg/mL) = mg in the vial ÷ mL of solvent
- Volume per sample (mL) = amount per sample (mg) ÷ concentration (mg/mL)
- 1 mg/mL = 1 µg/µL · 1 mL = 1000 µL
Reconstitution per vial — solvent: Peptide Matrix Water. Concentration after addition (1 mg/mL = 1 µg/µL):
| Vial | + 1 mL | + 2 mL | + 3 mL |
|---|---|---|---|
| 1500 mg | 1500 mg/mL | 750 mg/mL | 500 mg/mL |
👉 For any vial and solvent volume — use the calculator. It calculates the concentration (mg/mL, µg/µL) and the volume per sample (mL, µL).
Storage
BEFORE RECONSTITUTION
Room temperature, protected from direct light, in the original packaging. Refrigeration is not mandatory.
AFTER RECONSTITUTION
+2 °C to +8 °C, up to 60 days with Peptide Matrix Water. Discard the remainder after this period.
FREEZING
Not recommended. Freeze/thaw cycles degrade the structure of the peptide.
Four mistakes to avoid
1. Shaking for “faster dissolution”
Foam = denaturation. Only gentle swirling between the palms.
2. Unsuitable solvent
For the stability of the peptide structure, use only a sterile, purpose-designed solvent — Peptide Matrix Water is recommended.
3. Ignoring slight cloudiness
If it is not completely clear = the sample does not meet the criteria for work.
4. Removing it from the refrigerator “for an hour or two”
Short exposures add up and jeopardise stability.
