    Product Description

    GLYX 13 is a monoclonal antibody-derived tetrapeptide that acts as a partial agonist at the glycine site of the N-methyl-D-aspartate (NMDA) receptor.1,2 It is active in vivo when administered intravenously, and it readily passes through the blood-brain barrier.1,3 GLYX 13 has diverse effects in animals, as it blocks neuropathic pain, enhances learning and memory, and significantly reduces anxiety.2,3,4 GLYX 13 induces rapid antidepressant-like effects in animal models and rescued normal behavior in a rat model of autism.5,6,7

    WARNING This product is not for human or veterinary use.
