Glutathione is a tripeptide antioxidant produced in every cell, but oral bioavailability sits around 10%. Injectable routes deliver 100% to circulation. One RCT showed skin brightening in 37.5% of subjects after 12 IV sessions. Community protocols center on 200 to 400 mg subcutaneous, two to three times weekly. No FDA-approved injectable product exists.
200mcg · 2x/week
Summary: Add 3mL BAC water to your 1500mg vial. Draw to < 0.1 units on a U-100 syringe for a 200mcg dose. This vial will last 7500 doses.

A standard compounded vial is 1,500 mg. Add 3 mL bacteriostatic water and you get a concentration of 500 mg/mL. At that concentration, a 200 mg dose is 0.4 mL, which is 40 units on a U-100 insulin syringe. A 400 mg dose is 80 units. A 600 mg dose is 120 units, which exceeds a standard 1 mL syringe; split it into two 60-unit injections or use a 3 mL syringe with a 27G needle. GSH is light-sensitive. Store vials away from direct light, refrigerated at 2 to 8 degrees Celsius. Reconstituted vials stay good for about four weeks. The thing most beginners miss: oral NAC (N-acetylcysteine) between injection days supports endogenous GSH synthesis and is significantly cheaper. Stacking 600 to 1,200 mg oral NAC on off-days extends the benefit of your injection protocol without adding injection frequency. Vitamin C (1 to 2 g oral) directly regenerates oxidized GSSG back to reduced GSH through the ascorbate-glutathione redox cycle.
