DSIP
Delta Sleep-Inducing Peptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu
A naturally occurring nonapeptide first isolated from rabbit brain in 1977. Studied for its role in sleep regulation, stress response, and pain modulation. Popular in the biohacking community for sleep optimization.
A synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation and Gerontology — the same institution behind Epitalon. Pinealon is designed to target the central nervous system and pineal gland, with research focused on neuroprotection, cognitive function, and circadian rhythm regulation.
Modulates sleep architecture by influencing GABA, serotonin, and glutamate signaling. Promotes slow-wave (delta) sleep without suppressing REM. Also appears to modulate cortisol and ACTH, potentially reducing stress-related sleep disruption.
Penetrates the blood-brain barrier and accumulates in neurons. Modulates gene expression related to neuronal survival and function. Reduces oxidative stress in neural tissue. Appears to regulate melatonin synthesis through pineal gland activity, supporting circadian rhythm normalization.
