How Researchers Actually Dose Glutathione
Across 10,983 Glutathione calculator runs logged by the WPA community, the most common dose entered is 200mg, most often once weekly. The size researchers calculate against most often is the 1500mg bottle (6,708 runs). The most common bacteriostatic water volume is 3mL, which is what sets the draw marks on the syringe for that dose.
About Glutathione
Glutathione (GSH) is the body's main intracellular antioxidant tripeptide, most often sourced for detox, skin, and recovery research via IV, IM, or liposomal forms. Injectable research material ships as a lyophilized powder reconstituted with bacteriostatic water before use.
Its reported half-life is ~10 min (IV), which is the main reason the community cadence above looks the way it does. Not FDA-approved as a drug.
Reading Glutathione Nasal Spray Listings
Nasal spray listings are ranked on total Glutathione per bottle, so a lower-priced bottle at a lower concentration can still be the more expensive option per milligram. Where a vendor publishes it, the mcg or mg delivered per spray is what determines how many doses a bottle actually contains.
A nasal spray COA should confirm the active ingredient's purity, and — where available — the preservative system and pH range, which do not appear on a vial COA. Intranasal delivery differs from injection in absorption kinetics, so vial protocols do not carry over.
