How the DSIP calculator works
Lyophilized (freeze-dried) powder in a sealed vial, labelled in milligrams. The quick-fill buttons in the calculator are the vial sizes DSIP is commonly labelled in (2 mg and 5 mg). If yours is different, type it in.
Amounts of DSIP are usually written in micrograms (mcg), so the calculator opens in mcg.
For a field-by-field walkthrough and a guide to syringe types, see the main peptide calculator.
DSIP concentration table
Each labelled vial size at the same three round water volumes used across this site. It shows how the arithmetic behaves and is not a suggestion of what to use.
| Vial | Water added | Concentration | Each mark holds |
|---|---|---|---|
| 2 mg vial | 1 mL | 2 mg/mL | 20 mcg per unit |
| 2 mg vial | 2 mL | 1 mg/mL | 10 mcg per unit |
| 2 mg vial | 3 mL | 0.67 mg/mL | 6.7 mcg per unit |
| 5 mg vial | 1 mL | 5 mg/mL | 50 mcg per unit |
| 5 mg vial | 2 mL | 2.5 mg/mL | 25 mcg per unit |
| 5 mg vial | 3 mL | 1.67 mg/mL | 16.7 mcg per unit |
Every row for a given vial holds the same total. To compare volumes for a specific reading, use the BAC water calculator.
The formula, step by step
The “Try example numbers” button uses one fixed rule on every page: the smallest labelled vial, 2 mL of water, and whatever amount lands on the 10-unit mark. The amount is a by-product of that rule and not a typical or suggested DSIP dose.
- Concentration: 2 mg ÷ 2 mL = 1 mg/mL.
- The 10-unit mark is 10 ÷ 100 = 0.1 mL, which holds 0.1 × 1 = 0.1 mg (100 mcg).
- Run it forwards to check: 0.1 mg ÷ 1 mg/mL = 0.1 mL, and 0.1 × 100 = 10 units.
DSIP: general reference
General educational reference for research purposes only. None of it is a recommendation, none of it is medical advice, and none of it is used by the calculator, which works only on the numbers you enter.
DSIP is a peptide of nine amino acids. Its full name, delta sleep-inducing peptide, describes the experiment it was discovered in, not an established effect in people. Its international nonproprietary name is emideltide.
It was isolated in 1977 by the Schoenenberger and Monnier group in Basel, from the blood of rabbits. Decades later its gene and its receptor had still not been identified, and a 2006 review in the Journal of Neurochemistry called it “a still unresolved riddle”.
It breaks down quickly. In laboratory tests in plasma its half-life is about 15 minutes, because enzymes clip amino acids from one end.
It has not been approved as a medicine by any major regulator.
- Class
- Nine-amino-acid neuropeptide
- Group
- Short peptides (3 to 9 amino acids)
- Also known as
- Delta sleep-inducing peptide, Emideltide
- Molecular weight
- About 849 Da
- Half-life
- About 15 minutes in laboratory plasma tests. In vitro studies report a half-life of roughly 15 minutes in plasma, and it is thought to be shorter still in the body. No human pharmacokinetic study of injected DSIP is available.
- Regulatory status
- Not approved as a medicine. DSIP is not approved as a medicine by the FDA, the EMA or any other major regulator. Its position in US pharmacy compounding changed in 2023 and again in 2026 and remains under FDA review, so check the FDA’s current bulk drug substances lists.
- Labelled vial sizes
- 2 mg and 5 mg
Arithmetic slips to watch for with DSIP
Two names on the label
DSIP and emideltide are the same compound. A vial labelled with either name is handled identically, and the arithmetic does not change.
Small vials, small numbers
With 2 mL of water a 2 mg vial is 1 mg/mL, or 10 mcg per unit on a U-100 syringe, and a 5 mg vial is 2.5 mg/mL, or 25 mcg per unit. Low concentrations make small amounts easier to read on the scale.
What this page does not do
The calculator performs mathematical conversions only. It does not recommend, suggest or verify any DSIP dose or schedule, it does not say how much water to add, and it does not say what DSIP is for, whether it is safe, or whether it is legal where you live. It is not medical advice, diagnosis or treatment, and Peptrack does not sell, supply or endorse any substance.
Always confirm measurements with a licensed healthcare provider or pharmacist. See the full disclaimer.
