Stress axis regulation DSIP acts as what researchers call a "stress-limiting factor." It modulates the hypothalamic-pituitary-adrenal (HPA) axis, the hormonal cascade responsible for your body's stress response

In vivo , intraperitoneal administration of the NRF2 activator RTA-408 significantly upregulated NRF2 expression in neurons of SOD1 G93A transgenic mice, which consequently elevated the expression of GSH, SLC7A11, and GPX4, reduced MDA and ROS levels, suppressed neuronal ferroptosis, lipid peroxidation, and mitochondrial injury, and ameliorated weight loss and motor dysfunction in mice (Yang et al., 2023)

Epithalon Epithalon (Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed from natural pineal gland peptides

This compound is a tripeptide (a short chain of three amino acids) bound to a copper ion
