DSIP dosage calculator
The DSIP dosage calculator above converts a target dose into exact syringe units based on your vial size and how much bacteriostatic water you used to reconstitute it. DSIP is commonly sold in 2 mg, 5 mg vials. The calculator supports both U-100 and U-40 insulin syringes and flags draws that are too large for the syringe barrel or too small to measure accurately. A nine-amino-acid peptide originally isolated from cerebral venous blood, studied for its role in sleep and stress-response mechanisms. Enter your target dose in the calculator above to see the exact number of units to draw.
DSIP dosage chart
| Sample dose | Concentration | Volume to draw | Units on U-100 |
|---|---|---|---|
| 88 mcg | 2.5 mg/mL | 0.035 mL | 3.5 |
| 180 mcg | 2.5 mg/mL | 0.072 mL | 7.2 |
| 350 mcg | 2.5 mg/mL | 0.14 mL | 14 |
| 700 mcg | 2.5 mg/mL | 0.28 mL | 28 |
| 1400 mcg | 2.5 mg/mL | 0.56 mL | 56 |
DSIP and Sleep peptides
DSIP is a Delta sleep-inducing peptide (nonapeptide). A nine-amino-acid peptide originally isolated from cerebral venous blood, studied for its role in sleep and stress-response mechanisms.
How to reconstitute DSIP
Reconstituting DSIP is the same unit-conversion process used for any lyophilized peptide:
- Draw your chosen volume of bacteriostatic water into a syringe.
- Inject the bacteriostatic water slowly down the side of the DSIP vial — do not shoot it directly onto the powder.
- Swirl gently until the powder fully dissolves. Do not shake.
- Store the reconstituted vial refrigerated.
- To dose, calculate your draw volume: divide your target dose by the concentration (vial mg ÷ water mL = mg/mL). The calculator above does this automatically.
For DSIP specifically, 2 mg, 5 mg vials are common. A typical reconstitution adds 2 mL of bacteriostatic water, producing a concentration of 2.5 mg/mL for the 5 mg vial size.
DSIP half-life and storage
Published pharmacokinetic studies report a very short plasma half-life for the DSIP parent peptide, on the order of 7 minutes in some reports, with downstream physiological effects measured to persist beyond the circulating half-life.
Lyophilized DSIP is typically stored refrigerated or frozen. Reconstituted solutions are commonly refrigerated and protected from light.
Common DSIP dosing mistakes
- Confusing mg and mcg. 1 mg = 1,000 mcg. Always convert to the same unit before computing the draw.
- Using a U-40 syringe with U-100 math. Same printed mark, 2.5× the physical volume. Always check the syringe label.
- Not labeling the vial. Write the reconstitution date and concentration on the vial the moment you mix it.
- Under-diluting. If your draw is less than about 1 unit, the volume is too small to read accurately — add more bacteriostatic water next time.
