Reduced Glutathione Raw Material CAS 70-18-8, Bulk Quantity Supply, Custom Packaging Support, Lab-Grade Fine Powder

Glutathione (GSH, reduced L‑Glutathione) is a naturally‑occurring endogenous tripeptide composed of glutamic acid, cysteine and glycine. It is widely applied in pre‑clinical lab studies for antioxidant mechanism, cellular redox homeostasis, oxidative stress research, cell apoptosis, biochemical metabolism and antioxidant related compound screening.

Our Glutathione is white crystalline powder. Each batch undergoes strict HPLC and mass spectrometry testing to ensure purity above 99%. Relevant test documents can be provided upon customer request.

Notice❗: For laboratory research use only, not for human or animal therapeutic use.

Packaging

Inner package adopts medical glass vials sealed tightly with rubber stopper and aluminium cap, each vial marked with batch info. Vials are fixed in shockproof foam tray to avoid breakage, then packed into thick cartons equipped with desiccants to prevent dampness. Neutral packaging and custom specification such as 5mg/15mg per vial are supported.

Delivery

In‑stock goods will be dispatched within 3‑5 working days after confirmation. Temperature‑sensitive lyophilized peptides will be shipped with ice packs cold chain to keep stable quality during transit. We offer multiple logistics options including international express, air freight and sea freight according to order volume. Tracking information and customs documents will be supplied after shipment.
