DSIP Reconstitution Calculator
Delta sleep-inducing peptide, a nonapeptide studied in sleep and neurological research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted DSIP preparation, plus the mass-to-molar conversions for its stated molecular weight. Everything runs in your browser; nothing is transmitted or stored.

The pre-filled example, step by step
The inputs above are the neutral reference preparation this site uses everywhere the calculator appears: a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of DSIP and not an amount anyone should draw — they exist so the arithmetic is visible before you change anything.
- Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for DSIP is approximately 2.945 mM at its stated molecular weight.
- Per syringe unit. A U-100 syringe divides 1 mL into 100 units, so one unit holds 2,500 mcg ÷ 100 = 25 mcg.
- Volume for the 250 mcg target. 250 mcg ÷ 2,500 mcg/mL = 0.1 mL, or 10 units on that syringe.
- Preparations per vial. 5,000 mcg ÷ 250 mcg = 20 preparations.

Mass and molar equivalents for DSIP
Derived from the molecular weight recorded on the DSIP entry: 848.8 g/mol. Concentration in molar units is what an in-vitro protocol is usually specified in.
| Quantity | Molar equivalent |
|---|---|
| 1 mg of DSIP | 1,178 nmol (1.178 µmol) |
| 1 mcg of DSIP | 1.178 nmol |
| A 1 mg/mL solution | 1.178 mM (1,178 µM) |
Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.

Handling questions for DSIP
What does DSIP's short half-life imply for research design?
DSIP is reported to have a serum half-life on the order of only several minutes and limited in vitro stability. This short exposure, combined with the observation that effects may involve carrier-protein complexes or precursor forms, is an important consideration when timing sleep-related endpoints in studies.
How is DSIP administered in research?
In research protocols DSIP is typically given by subcutaneous injection, and some human sleep studies used intravenous dosing scaled to body weight. It is supplied as a lyophilized peptide requiring reconstitution before use.
