Glutathione (L-γ-Glutamyl-L-cysteinyl-glycine) is a naturally occurring tripeptide antioxidant found in virtually all mammalian cells. In its reduced form (GSH), it is the most abundant intracellular antioxidant and serves as the primary cellular defense against oxidative stress. Heartland Bio Labs supplies Glutathione (reduced form) as a high-purity lyophilized research compound for qualified laboratory applications.

Glutathione is among the most extensively studied molecules in cellular redox biology. Research has characterized its roles in reactive oxygen species (ROS) scavenging, xenobiotic detoxification, immune cell function, protein disulfide regulation, and mitochondrial protection. The GSH/GSSG ratio is a widely used biomarker in oxidative stress research. Glutathione is also studied in the context of detoxification pathway biology and its interactions with glutathione S-transferase enzymes.

Handling Information
Handle under standard laboratory conditions. Glutathione (reduced form) is susceptible to oxidation when exposed to air. Handle quickly, minimize exposure to oxygen, and store in tightly sealed containers. Use appropriate PPE. This compound is intended for qualified research use only.
Storage Requirements
- Long-term (lyophilized): Store at -20°C, protected from light and oxygen
- Short-term (in solution): Use immediately or store at -80°C; do not store reconstituted solution at 4°C for extended periods
- Keep in original sealed vial under inert gas conditions when possible
How should I store this peptide?+
Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.
What should I reconstitute it with?+
Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.
How quickly do orders ship?+
Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.
Is the COA verified independently?+
Yes. Every product is tested by HPLC for purity (target COA-verified purity) and mass spectrometry for molecular identity before release. The COA is generated from the actual test data, not a generic template.
Can I get bulk or institutional pricing?+
Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
