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.

Storing and handling Glutathione 1500mg

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.

Glutathione 1500mg questions

Are research peptides like Glutathione 1500mg legal in Canada?

Glutathione 1500mg is supplied here strictly as a reference material for in vitro laboratory research. For laboratory research use only. Not for human or veterinary use. Canadian law turns on what a substance is represented and supplied for, which is why that restriction is on the label, the invoice and every page of this site. The full framework, and what a research-use designation does and does not change, is set out on our legality page.

Is Glutathione 1500mg shipped from within Canada?

Yes. Every Glutathione 1500mg order leaves British Columbia, Canada and travels entirely within the country. 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. Transit after dispatch is 2–5 business days Canada-wide, with a tracking number on every parcel, and orders over CA$200 ship free.

Does Glutathione 1500mg come with a certificate of analysis?

Yes — the certificate for the lot in your box, not a representative certificate for a different batch. Every Glutathione 1500mg lot is released against a >99% HPLC specification, and the document carries the lot number, the issuing laboratory and the analytical method. Certificates are not published on this site; if you need another copy, ask us for it by lot number.

How is Glutathione 1500mg supplied and stored?

As a lyophilised powder in a sealed vial, which is the form that survives shipping without a cold chain. Unopened vials are stored away from light and moisture; the storage and handling page covers the laboratory conditions in full. We publish no dosing, reconstitution volumes or administration guidance of any kind.

What fill is Glutathione 1500mg supplied in?

Glutathione 1500mg is supplied in a single 1,500mg fill, released against a >99% specification.
