Physician-Supervised 503A Glutathione Subcutaneous Dosing Guide
Step-by-step milligram-to-unit conversions, titration schedules, injection sites, and side-effect avoidance
What is the Recommended Subcutaneous Dosage for Injectable Glutathione?
The standard clinical dosage for subcutaneous compounded glutathione is 100mg to 200mg administered two to three times weekly. At a typical 200mg/mL concentration, this corresponds to 50 to 100 units on a standard 31-gauge U-100 insulin syringe, providing optimal steady-state tissue saturation. Subcutaneous administration into adipose tissue provides zero-order sustained release kinetics, maintaining consistent enzymatic availability for glutathione peroxidase and glutathione S-transferase without renal filtration spikes.

Expert Clinical Perspective:
“Starting patients at 100 milligrams twice weekly allows the liver to adapt smoothly to increased Phase II conjugation demands. Patients who titrate responsibly experience zero Herxheimer reactions, noting improved morning energy, reduced brain fog, and visible skin clarity within three to four weeks.”
