About Glutathione 1500mg
The gamma linkage between glutamate and cysteine is what makes glutathione distinctive: it resists standard peptidase cleavage, which is why the molecule survives long enough to reach the concentrations it does intracellularly, typically millimolar. Its function depends on the reduced-to-oxidised ratio rather than on absolute concentration, so GSH/GSSG is the measurement that matters in most experiments. It also serves as the conjugating substrate for glutathione S-transferases in xenobiotic clearance. This 1,500mg vial is a large presentation reflecting the high molar quantities these assays consume.
Storage and reconstitution
Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.
Shipping within Canada
Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
