The sequence was Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val (in case youre intrigued by the chemistry!) Across the next three decades, the same group and a handful of collaborators published several hundred preclinical studies showing the peptide healed wounds, repaired tendons, attenuated NSAID toxicity, fixed gut lesions, and reduced symptoms in animal models of depression, schizophrenia, and Parkinsons disease

Human clinical trials are ongoing, showing, so far, good safety and tolerability
While the precise regulatory pathways continue to be studied, findings suggest that glutathione plays a foundational role in supporting biological processes related to cognitive resilience, metabolic balance, and long-term cellular health
