What it is
A nonapeptide originally isolated from rabbit cerebral venous blood during electrically induced sleep.
How it works
Mechanism is poorly characterized; preclinical studies suggest modulation of GABAergic and neuroendocrine systems without binding to a specific identified receptor.
Where it's used
Studied in early research literature for effects on sleep architecture and stress response; no current clinical use.
Regulatory status
Not FDA-approved; research compound.
Reconstitution
Supplied as a lyophilized powder requiring reconstitution with bacteriostatic water prior to use.
Tracking it
DSIP is injectable, so two things matter in a log: when you dosed and where. Rotating sites and writing both down prevents the classic “did I already pin the left side?” problem. with a half-life of about 24 minutes, a dose log also lets a tracker model the relative amount still in your system between doses.
