DSIP Dosage Guide: Reported Ranges, Units & Reconstitution

Reported DSIP study arms, mg-to-insulin-unit conversion tables, reconstitution volumes and handling notes.

DSIP amounts reported in the literature

DSIP is a nonapeptide isolated from rabbit cerebral venous blood studied in sleep-architecture research. The table below summarizes the arms described in published protocols. It is a literature reference, not a protocol to follow.

Study arm	Reported amount	Cadence
Standard arm	100–250 mcg	nightly

Concentration math

Standard preparation: 5 mg + 2 mL = 2.5 mg/mL. On a U-100 insulin syringe, 100 units = 1 mL, so:

Concentration	0.5 mg	1 mg	2 mg	5 mg
2.5 mg/mL	20 units	40 units	80 units	—
5 mg/mL	10 units	20 units	40 units	100 units
10 mg/mL	5 units	10 units	20 units	50 units

Change the diluent volume and every number changes proportionally. The peptide calculator does the conversion for any vial size and target amount.

Why escalation intervals in the literature are long

Across published protocols in this class, step-ups are spaced in multi-week blocks rather than compressed. Study designs prioritize tolerability data at each level before advancing, which is why the reported schedules look conservative compared to what circulates informally.
