Research & reference information

This profile compiles research and community-sourced reference information for educational purposes. Information may evolve as research and community knowledge develop. It is not individualized medical advice.

Overview

Your body’s master antioxidant.

Injected for liver support, brighter skin, and bouncing back from oxidative stress.

Mix it fresh, it breaks down fast.

What It Does

Master antioxidant tripeptide central to oxidative stress defence, liver detox, and immune function.

Directly neutralises ROS, regenerates vitamins C and E, supports liver Phase II detox, and maintains mitochondrial integrity.

Reconstitution Calculator

Enter the vial amount and diluent volume to calculate concentration. If you already have a target amount, you can also convert it to liquid volume and syringe markings. This tool does not recommend a target amount.

Calculated concentration—Enter both values above.
Optional conversion

Enter a target amount you already have and select the syringe capacity.

Calculated draw—Enter concentration inputs and a target amount.

Mathematical reference only. The calculator does not determine an appropriate target amount. Syringe capacity only changes the maximum volume that fits.

Maintenance1–2×/week200 mgOngoing antioxidant support. Drop to once-weekly after the 8-week loading + working phase if benefit holds.
Off2–4 weeks–Essential break. Skipping leads to tolerance and diminishing returns.
Cycle & Timing

4 weeks on / 4 weeks off. Max: 12 weeks on / 4–8 weeks off. Hepatic methylation cycling supports best results with breaks.

Timing

Daily SubQ, reconstitute fresh; oxidizes within hours.

Population Considerations

Unisex antioxidant, same protocol for men and women, no cycle effect. Confirm with a prescriber in pregnancy.

Handling & Stacking

Injection site
Upper outer glute preferred. Abdomen acceptable.
Storage
  • Freeze-dried: -4°F (stable long-term).
  • Reconstituted: use fresh, do not store for weeks.
  • Glutathione oxidizes to GSSG within hours at room temperature or once exposed to air/light; kept cold (36–46°F) and dark in the sealed amber vial it lasts only a few days.
  • Discard the moment it yellows (that’s oxidation).
  • Never room temperature; never freeze (ice crystals denature the tripeptide).
Side effects
Upper glute sting (brief). Flushing or garlic taste within 30 min. Reconstitute fresh only.
What to expect
  • Energy improvement and reduced oxidative fatigue within 2–4 weeks.
  • Skin brightening reported by many users.
  • Must reconstitute fresh, oxidises within hours of reconstitution.
  • Supply math 600mg → 8 vials | 1500mg → 4 vials (8-wk @ 200 mg × 3/wk) Fresh-dose note: a reconstituted vial covers ~3 doses but would sit refrigerated across the week, if you want each dose truly fresh, reconstitute a smaller vial (or add less BAC water for fewer doses) more often rather than holding one vial for several days.
Pairs well with
NAD+ (cellular redox stack); GHK-Cu (additive antioxidant); Vitamin C (recycle glutathione); BPC-157 (gut + systemic recovery); MOTS-c (mitochondrial)
Avoid
Sulfa allergy (theoretical). Concurrent chemotherapy (may interfere, physician supervision)

Safety & Patient Education

Contraindications
Sulfa allergy (theoretical, reaction-prone individuals), concurrent chemotherapy without oncology supervision
Warnings
Must be reconstituted fresh; oxidizes within hours. FDA has flagged compounded IV glutathione for skin-lightening use as an unproven indication with serious adverse event reports.
Drug interactions
Chemotherapy (cisplatin, doxorubicin, cyclophosphamide and others): glutathione may reduce both toxicity AND efficacy; do NOT combine outside an oncologist-supervised protocol Acetaminophen overdose treatment (N-acetylcysteine pathway): glutathione is the protected metabolite, supplemental IV/SubQ glutathione may augment NAC therapy but is not a substitute Warfarin: theoretical mild potentiation via reduced oxidative stress on coagulation factors; monitor INR if combining chronically Sulfa drugs (sulfonamide antibiotics, sulfasalazine, some diuretics): increased reaction risk in sulfa-allergic patients given the sulfhydryl group Methylating agents and SAMe: complementary methylation/redox support; theoretical synergy, no human interaction data
Labs
  • Compound-specific: CBC baseline; liver enzymes (AST/ALT, bilirubin) and renal function (BUN/creatinine, eGFR) at baseline and periodically through any repeated IV course, especially above ~5 g/dose (documented hepatotoxicity signal), Out of range?
  • Rising ALT/AST or bilirubin = hepatic stress from high-dose glutathione → cut the dose or space out the infusions; a falling eGFR = renal strain → hold and hydrate.
Stop criteria
Rash, hives, or sulfhydryl-type allergic reaction; severe injection-site irritation
Patient education
  • Reconstitute immediately before use; discard unused, glutathione oxidizes within hours and is no longer active.
  • Do not use during active cancer treatment without oncology coordination.
  • Skin-lightening use is unproven and the FDA has issued safety warnings about compounded IV products marketed for that purpose.
