Chemical identity

What Glutathione is

Glutathione (L-glutathione, reduced form, GSH) is a tripeptide in which L-glutamate is linked through its side-chain gamma-carboxyl group to L-cysteine, which is in turn linked to glycine: gamma-L-Glu-L-Cys-Gly. Because of the gamma-peptide bond it is not a conventional alpha-linked tripeptide. The molecular formula is C10H17N3O6S, molecular weight 307.32 g/mol (monoisotopic mass 307.08 Da), CAS Registry Number 70-18-8, PubChem CID 124886 and UNII GAN16C9B8O. The free thiol of the cysteine residue distinguishes the reduced form (GSH) from the disulfide-linked dimer, oxidized glutathione (GSSG, C20H32N6O12S2, 612.6 g/mol, CAS 27025-41-8). Pepta Labs lists glutathione as 1200 mg of lyophilized powder per sealed glass vial, typically supplied as the free acid rather than a peptide salt, with reported RP-HPLC purity (99.0% on the current listing) and identity confirmed by mass spectrometry. Store at 2-8 C or -20 C, dry and protected from light, since the thiol oxidizes on exposure to air. For laboratory research use only.

Residues: 3 amino acids
Salt form: typically supplied as the free acid (no counter-ion)

Questions

Glutathione 1200mg — common questions

What sizes of glutathione does Pepta Labs sell?

One: the 1200 mg vial on this page. Pepta Labs does not list a smaller or larger glutathione vial, so a larger quantity means ordering more than one 1200 mg vial with the quantity selector on this page.

What is in a Glutathione 1200mg vial as supplied?

A supplier-stated 1200 mg of reduced L-glutathione as dry lyophilized powder in a sealed glass vial. The label names the compound, the quantity and the research-use designation; it carries no lot or batch number. The quantity per vial is stated by the supplier and is not measured vial by vial.

Is Pepta Labs glutathione a salt or the free acid?

Glutathione is typically supplied as the free acid, with no counter-ion such as trifluoroacetate or acetate. That differs from many longer research peptides, whose powder weight includes counter-ions. Net peptide content is not reported for this listing.

How do I get the HPLC and mass spec report for glutathione 1200mg?

Request it on this page or email support@peptalabs.com with the compound name and quantity, and it is sent by email, before you order if you want to see it first. The report covers a sampled production run from the source, not an individual vial. Purity is the RP-HPLC area percentage; identity is shown by mass spectrometry, where the observed mass should correspond to glutathione's calculated monoisotopic mass of 307.08 Da once the ion form stated on the report is taken into account (a protonated [M+H]+ ion reads about 1 Da higher). The Learn guide How to Read and Verify a Peptide Certificate of Analysis walks through each field.

How should sealed glutathione powder be stored?

Refrigerate the sealed vial at 2-8 C on arrival, or hold it at -20 C for long-term storage, dry and away from light. The free thiol on the cysteine residue oxidizes on contact with air, forming the disulfide dimer GSSG, so keep the vial sealed until it is opened in the lab. The Learn guide Storage Temperature and Handling of Lyophilized Research Peptides covers dry-powder storage in more depth.

Is Glutathione 1200mg shipped cold?

No. It ships to US addresses only as dry lyophilized powder at ambient temperature, with free US shipping and no minimum. No cold pack is used; refrigerate the vial when it arrives.

What does Glutathione 1200mg cost?

Glutathione 1200mg starts at $60.10 per vial. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. Glutathione 1200mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

What is the difference between reduced glutathione (GSH) and oxidized glutathione (GSSG)?

GSH is the single tripeptide with a free cysteine thiol (C10H17N3O6S, 307.32 g/mol, CAS 70-18-8). GSSG is two GSH molecules joined by a disulfide bond between their cysteine residues (C20H32N6O12S2, 612.6 g/mol, CAS 27025-41-8). Pepta Labs lists the reduced form.

Why is glutathione called a gamma-glutamyl peptide?

The glutamate residue is joined to cysteine through its side-chain (gamma) carboxyl group rather than the alpha-carboxyl used in ordinary peptide bonds. This gamma linkage is part of the structure confirmed by mass spectrometry and distinguishes it from alpha-Glu-Cys-Gly.

What does the CAS number 70-18-8 identify?

CAS 70-18-8 is the registry number for reduced L-glutathione as the free acid. The oxidized dimer and metal or ester derivatives carry different CAS numbers, so the number identifies exactly which form is listed.
