Glutathione Dosage Chart & Schedule Guide.
Glutathione (GSH) is the body's master antioxidant, critical for detoxification, immune function, and cellular protection against oxidative stress. Injectable glutathione bypasses poor oral bioavailability for superior systemic absorption.

Timing
Inject in the morning on an empty stomach for best antioxidant support throughout the day. Administer vitamin C separately — do not mix in the same syringe as it can cause precipitation.
Cycling
Run a loading phase of 2–3×/week for 4–8 weeks, then transition to 1×/week maintenance. Glutathione is endogenous so continuous use is possible, but 12 weeks on / 4 weeks off is a common protocol.
Stacking
Pair with oral NAC (600 mg daily) to support endogenous glutathione production. Vitamin C (500–1,000 mg) helps recycle oxidized GSSG back to active GSH. Monitor zinc levels with long-term use.
Storage
Store lyophilized powder at -20 °C or 2–8 °C. After reconstitution with bacteriostatic water, refrigerate and use within 30 days. GSH oxidizes rapidly — discard if solution turns yellow or cloudy.
