DSIP reconstitution diagram DSIP: 5 mg vial mixed with 2 mL bacteriostatic water yields 2.5 mg/mL. A 100 mcg dose draws to 4 units on a U-100 syringe. 1 Reconstitute 5 mg vial + 2 mL BAC water 2 Calculate concentration 2.5 mg/mL 5 mg ÷ 2 mL = 2.5 concentration 3 Convert dose to volume 100 mcg dose 100 mcg ÷ 2500 mcg/mL = 0.04 mL 4 Draw to mark 0 25 50 75 100 4 units U-100 5 mg vial · 2 mL water · 2.5 mg/mL · 100 mcg dose → 0.04 mL → 4 units on U-100

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.

How to reconstitute DSIP

Reconstituting DSIP is the same unit-conversion process used for any lyophilized peptide:

  1. Draw your chosen volume of bacteriostatic water into a syringe.
  2. Inject the bacteriostatic water slowly down the side of the DSIP vial — do not shoot it directly onto the powder.
  3. Swirl gently until the powder fully dissolves. Do not shake.
  4. Store the reconstituted vial refrigerated.
  5. 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.
