Glutathione (600mg): The Cell's Master Antioxidant Tripeptide
Glutathione is a tripeptide of glutamate, cysteine and glycine present in every cell at millimolar concentrations, higher than almost any other small molecule. Its cysteine thiol is the cell's main buffer against oxidative stress, the substrate for detoxifying enzymes, and the recycler of other antioxidants including vitamins C and E. Cellular glutathione falls with age, and the ratio of reduced to oxidised glutathione (GSH:GSSG) is the standard laboratory measure of oxidative stress.

Pure Peptides Australia holds Glutathione in Sydney stock as a 600mg lyophilised vial, Janoshik tested before listing. Orders confirmed before 12pm AEST on a business day are dispatched the same day with tracked delivery Australia-wide.

Why the vial rather than a capsule
Oral glutathione is largely broken down in the gut before absorption, which is why supplement studies show small or inconsistent changes in blood levels and why research uses the reduced form direct. The 600mg lyophilised vial supplies L-glutathione in its reduced (GSH) state, sealed under nitrogen so it does not oxidise to GSSG on the shelf. Reconstituted, it should be used quickly, because the thiol oxidises in solution within days.
Key research areas
Oxidative stress
GSH directly neutralises reactive oxygen species and is the cofactor for glutathione peroxidase, the enzyme that clears hydrogen peroxide and lipid peroxides.
Hepatic detoxification
Glutathione S-transferases conjugate toxins and drug metabolites to GSH for excretion; GSH depletion is the mechanism of paracetamol liver injury, treated clinically with the precursor N-acetylcysteine.
Ageing
Tissue GSH declines with age; restoring it is studied for mitochondrial function and markers of oxidative damage (Sekhar et al., American Journal of Clinical Nutrition 2011).
Skin pigmentation
Studied for shifting melanin synthesis from eumelanin toward pheomelanin by inhibiting tyrosinase, the basis of its use in dermatology research.
Immune function
Lymphocyte GSH levels govern proliferation and cytokine balance; studied in immune ageing.
Neurodegeneration
Low GSH in substantia nigra is an early finding in Parkinson's models; studied for neuronal protection.
How Glutathione works
The cysteine thiol donates an electron to neutralise a radical, and two oxidised glutathione molecules join as GSSG. Glutathione reductase, using NADPH, splits GSSG back to two GSH, so the pool cycles. Beyond direct scavenging, GSH is the substrate for glutathione peroxidases and S-transferases, regenerates ascorbate and tocopherol, and glutathionylates proteins to protect cysteine residues during oxidative bursts. Alongside NAD+, which supplies the NADPH that recycles it, it is one of the two large-mass redox compounds in longevity research.

Pricing in Australia
$159.99 for 600mg, $0.27 per mg
Glutathione is used in hundreds of milligrams per draw, so a 600mg vial is one to three draws. Because reconstituted GSH is used within a week, researchers running longer designs reconstitute in portions.
Reconstitution
Glutathione is a large fill and dissolves readily. Wipe the stopper, add bacteriostatic water slowly, swirl gently until clear, never shake. Refrigerate at 2 to 8ยฐC, keep from light and use within 7 days.
| Water added | Concentration | 200mg on a U-100 syringe | 300mg on a U-100 syringe |
| 3mL | 200mg/mL | 100 units (1mL) | 1.5mL |
| 6mL | 100mg/mL | 2mL | 3mL |
The reconstitution calculator runs the maths for any target.
Quality and COA verification
Every batch is tested by Janoshik Analytical: HPLC purity confirming the reduced form, identity against 307 g/mol, heavy metals and endotoxin. The batch number on the label matches the certificate.
Sydney stock, tracked delivery
No international transit or customs queue. Orders cleared before 12pm AEST leave the same business day; Express Post reaches most metro addresses in one to three business days.

Glutathione Australia FAQ
What is glutathione?
A tripeptide of glutamate, cysteine and glycine found in every cell at high concentration. Its cysteine thiol is the cell's main antioxidant buffer, the substrate for detoxifying enzymes, and the recycler of vitamins C and E.
Reduced or oxidised?
This vial is the reduced form, GSH, the active antioxidant state. Oxidised glutathione, GSSG, is what GSH becomes after neutralising a radical. The vial is sealed under nitrogen so it stays reduced on the shelf.
Why a vial and not a capsule?
Oral glutathione is largely broken down before absorption, giving small and inconsistent blood-level changes. Research uses the reduced form direct to control the amount delivered.
How does glutathione work?
Its thiol donates an electron to neutralise radicals, forming GSSG, which glutathione reductase recycles back using NADPH. It is also the cofactor for glutathione peroxidases and S-transferases and regenerates other antioxidants.
What does the research show?
Restored tissue GSH and lower oxidative-damage markers in ageing models, protection in paracetamol liver injury via its precursor NAC, tyrosinase inhibition in pigmentation models, and neuronal protection in Parkinson's models.
Can I buy glutathione at Chemist Warehouse in Australia?
Pharmacies sell oral glutathione and NAC supplements. A 600mg reduced-glutathione research vial is a different product, not a pharmacy item, and is supplied for laboratory use only.
How do you reconstitute glutathione?
Add 3 to 6mL of bacteriostatic water slowly, swirl gently until clear, never shake. Refrigerate at 2 to 8ยฐC, keep from light and use within 7 days. 3mL gives 200mg/mL, so 200mg is 1mL.
Why only 7 days once reconstituted?
The cysteine thiol oxidises in solution, converting GSH to GSSG. Reconstitute in portions for longer designs.
Is glutathione available in Australia?
As a research compound, yes: Pure Peptides Australia holds the 600mg vial in Sydney with same-day dispatch. Injectable glutathione is not a TGA-registered medicine in Australia.
Where can I buy glutathione in Australia?
From this page. Check out with card, PayID, Osko or bank transfer and the vial leaves Sydney the same business day when payment clears before 12pm AEST, tracked to any Australian address.
What does glutathione cost in Australia?
$159.99 for the 600mg vial, $0.27 per mg. No surcharge on PayID, Osko or bank transfer.
Is glutathione legal in Australia?
Pure Peptides Australia supplies it strictly for lawful in-vitro laboratory research. It is not approved by the TGA for human or veterinary use in this form and is not sold as a medicine, supplement or therapeutic good. Purchasers are responsible for ensuring their use complies with applicable laws.
