Peptide LibraryDSIP calculator
Delta sleep-inducing peptide (DSIP) was given to people in a series of small European studies in the late 1980s and 1990s, intravenously and dosed per kilogram of body weight; several found no effect on the hormones they measured, and no trial has been registered since. Vials are usually 5 or 10 mg. The calculator does the vial arithmetic; the studied dose is listed below as reported, not converted.

DSIP reconstitution chart
Concentration and micrograms per mark on a U-100 insulin syringe, by vial size and water added. The peptide amount never changes; only how concentrated it is.
| Vial | + 1 mL water | + 2 mL water | + 3 mL water |
|---|---|---|---|
| 5 mg | 5 mg/mL · 50 mcg per unit | 2.5 mg/mL · 25 mcg per unit | 1.67 mg/mL · 16.7 mcg per unit |
| 10 mg | 10 mg/mL · 100 mcg per unit | 5 mg/mL · 50 mcg per unit | 3.33 mg/mL · 33.3 mcg per unit |

Why the DSIP study doses are not converted to units
The published human studies of DSIP report doses per kilogram of body weight, not a fixed amount. Turning them into milligrams or syringe units would mean assuming a body weight, so this page lists them as reported and converts nothing. A fixed amount quoted elsewhere is not the same thing as a weight-based dose.

Common questions
How much bacteriostatic water do you add to a 5 mg DSIP vial?
There is no single correct volume: the amount of peptide is fixed and the water only sets the concentration. For 5 mg, 1 mL gives 5 mg/mL (50 mcg per unit), 2 mL gives 2.5 mg/mL (25 mcg per unit) and 3 mL gives 1.67 mg/mL (16.7 mcg per unit). More water makes each syringe mark hold less, which makes small amounts easier to measure accurately.
What dose does the DSIP calculator use?
None. The published human studies of DSIP report doses per kilogram of body weight (25 nmol/kg body weight), so they are not a fixed amount, and the calculator does not turn them into one. It converts a vial size, a water volume and an amount you enter into a volume and syringe units; the tables on this page show concentrations only.
What does one unit on an insulin syringe mean?
A unit is a volume mark, not an amount of drug. On a U-100 syringe 100 units fill 1 mL, so 10 units is always 0.1 mL; how much peptide those 10 units hold depends only on the concentration you mixed. U-40 syringes use 40 marks per mL, so the same volume reads as a different number of units.
