DSIP reconstitution calculator.
Work out the concentration of a reconstituted DSIP vial. Presets match the 10 mg format we stock, and the reference table below is calculated for those exact vials. Research use only.
This tool reports concentration only. It is not dosing guidance, and nothing here is for human use.
DSIP concentration reference table
Every combination of the DSIP vial sizes we stock and the bacteriostatic water volumes people most often add.
| Vial | BAC water | Concentration | Per 100 µL aliquot |
|---|---|---|---|
| 10 mg | 1 ml | 10 mg/ml | 1 mg (1,000 mcg) |
| 10 mg | 2 ml | 5 mg/ml | 0.5 mg (500 mcg) |
| 10 mg | 3 ml | 3.333 mg/ml | 0.333 mg (333 mcg) |
| 10 mg | 5 ml | 2 mg/ml | 0.2 mg (200 mcg) |
How the calculation works
Concentration is the mass of peptide divided by the volume of solvent. A vial holding 5 mg reconstituted with 2 ml of bacteriostatic water gives 2.5 mg/ml, so a 100 µL aliquot contains 0.25 mg. The powder itself adds no meaningful volume at these masses, which is why the water volume alone sets the concentration.
Handling in the Vietnamese climate
Sealed lyophilized vials are stable at room temperature in transit, which is why the material ships dry rather than cold. Once reconstituted, the solution is kept refrigerated and shielded from light. Bacteriostatic water is the usual solvent because the benzyl alcohol in it lets a vial be entered more than once.
What is DSIP?
A naturally occurring nonapeptide first isolated from rabbit brain research, studied for its link to sleep architecture.
Delta sleep-inducing peptide is a short nine-amino-acid sequence first identified in the 1970s during Swiss research into slow-wave ("delta") sleep in rabbits. The peptide was pulled directly from cerebral blood during deep sleep states, which is how it got its name. Unlike Semax or Selank, it was not designed; it is a naturally occurring signalling peptide.
Decades of follow-up research have not settled on a single receptor or pathway. DSIP appears to interact with multiple systems rather than one clean target, which is part of why it remains a research peptide rather than an approved medicine anywhere. Current interest centres on sleep-wake regulation and the body's stress response, both studied in animal and in-vitro models.

Common questions
What is DSIP?
A short nonapeptide first identified in sleep research, occurring naturally rather than being a designed analog like most peptides in this catalog. Listed here as a non-clinical research material, not for human use.
Is DSIP the same as a sleep medication?
No. It is not an approved sleep drug anywhere and this page makes no medical claim. It is sold strictly for laboratory research into sleep-related signalling.
How much bacteriostatic water do I add to a DSIP vial?
There is no single correct volume. The water volume sets the concentration: more water gives a weaker solution and a larger aliquot for the same mass. Common choices are 1 to 5 ml. Enter your vial size above to see what each volume produces for 10 mg.
What concentration does a DSIP vial give?
It depends entirely on the solvent volume. The reference table above lists every combination of the 10 mg vial format and 1, 2, 3 and 5 ml of bacteriostatic water.
Does the powder change the final volume?
Not measurably at these masses. A few milligrams of lyophilized peptide occupies a negligible volume, so the bacteriostatic water you add is effectively the final volume.
Can I use normal water or saline instead?
Bacteriostatic water is the standard solvent for multi-entry vials because it contains a preservative. Sterile water and saline have no preservative, so they are single-entry solvents.
