DSIP

Subcutaneous injection: typically 100-300 mcg administered in the evening before sleep. Clinical research used slow IV infusions at 25 nmol/kg. Very short half-life in vitro (~15 minutes) due to aminopeptidase degradation. Can cross the blood-brain barrier and is absorbed from the gut without denaturation.

Promotes delta (slow-wave) sleep patterns, though the exact receptor-level mechanism remains unclear. May selectively bind to regions of GABA-A, glycine, and/or NMDA receptors.

Modulates cortisol and ACTH levels, potentially acting as a stress-protective peptide that normalizes the HPA axis.

Interacts with components of the MAPK cascade and is homologous to glucocorticoid-induced leucine zipper (GILZ), affecting cell proliferation, differentiation, and apoptosis.

Influences release of LH and GH from the pituitary, suggesting neuroendocrine regulatory roles.

Influences levels and activity of serotonin (5-HT), glutamate, dopamine, and melatonin in the brain.

Promotes delta-wave (deep) sleep and may help normalize disturbed sleep patterns in insomniacs. Double-blind studies showed effects on chronic insomnia.

Normalizes cortisol and stress response, potentially reducing anxiety and stress-related sleep disruption.

Some research suggests analgesic properties, possibly through opioid receptor interaction.

May help normalize LH and GH secretion patterns, with potential downstream metabolic and recovery benefits.

The research aims to elucidate the sleep-promoting mechanism of DSIP-CBBBP, exploring its impact on ...
