1. Draw 3 mL bacteriostatic water with a sterile syringe.
2. Inject slowly down the vial wall; avoid foaming.
3. Gently swirl until dissolved (do not shake).
4. Label and refrigerate at 2 to 8 °C, protected from light. At 500 mg/mL, 1 unit = 0.01 mL = 5 mg on a U-100 insulin syringe.

Glutathione (GSH) is the body’s most abundant intracellular antioxidant, present in virtually every cell at concentrations of 1 to 10 mM. As a tripeptide composed of glutamate, cysteine, and glycine, it functions as the primary thiol-based redox buffer, neutralizing reactive oxygen species (ROS), supporting Phase II detoxification pathways, and facilitating the excretion of xenobiotics and heavy metals. The reduced form (GSH) donates electrons to neutralize free radicals and is then recycled back from its oxidized form (GSSG) by glutathione reductase. Clinical and preclinical research demonstrates that maintaining optimal GSH levels supports liver function, immune cell activity, mitochondrial protection, and overall cellular homeostasis.

Observations from preclinical and clinical literature.

• Supports reduction of oxidative stress markers and maintenance of cellular redox balance.
• May enhance liver function and support hepatic detoxification pathways.
• Research suggests immune-modulating effects, including support for natural killer cell activity and T-cell
  function.
• Clinical studies on skin health indicate potential effects on melanin index and skin brightness with
  sustained use.
• Generally well tolerated; occasional mild injection-site reactions (redness, itch) may occur.
• Rare reports of gastrointestinal discomfort with high-dose protocols; start with lower doses and titrate
  gradually.
