DSIP Reconstitution & Dosage Calculator
This free DSIP calculator turns your vial size, the bacteriostatic water you add, and your target amount into a concentration, a draw volume, and the exact units on a U-100 insulin syringe. DSIP — delta sleep-inducing peptide — is a nonapeptide first isolated from rabbit brain and studied for its effects on sleep architecture. It is handled in microgram amounts, so draws are small. This is a measurement tool — it does not recommend an amount.

What this DSIP calculator does
This calculator does one job well: it turns your vial size, the amount of bacteriostatic water you add, and your target amount into a concentration (mg/mL), a draw volume (mL), and the matching units on a U-100 insulin syringe. Change any input and the result updates instantly.
DSIP ships as a freeze-dried powder. Before it can be measured into a syringe it has to be reconstituted — dissolved in bacteriostatic water. How much water you add sets the concentration, and the concentration sets how many units each amount works out to. The presets above cover the most common DSIP vial setups; use the custom fields for anything else.
How to use the DSIP calculator
Pick your syringe
Choose the U-100 insulin syringe you'll draw with. Smaller syringes (0.3 mL / 30u) have finer lines, which helps when the draw is small.
Enter your vial and water
Set the milligrams in your DSIP vial and the bacteriostatic water you added. Together these set the concentration.
Set your target amount
Toggle mg or mcg and pick (or type) the amount you're measuring for. The calculator does the conversion for you.
Read the draw
The result panel shows concentration, draw volume, and the exact U-100 units to pull, plus how many doses your vial contains.
DSIP reconstitution math, explained
The math is short. Concentration = vial size ÷ bacteriostatic water. Draw volume = target amount ÷ concentration. Units = draw volume × 100 (a U-100 syringe reads 100 units per mL). The table below shows common DSIP setups and the units for a 1 mg amount at each.
| Vial size | Bac water | Concentration | Units per 1 mg |
|---|---|---|---|
| 5 mg | 1.0 mL | 5 mg/mL | 20 units |
| 5 mg | 2.0 mL | 2.5 mg/mL | 40 units |
| 5 mg | 2.5 mL | 2 mg/mL | 50 units |
| 5 mg | 5.0 mL | 1 mg/mL | 100 units |
| 10 mg | 2.0 mL | 5 mg/mL | 20 units |
DSIP amount-to-units reference
How common amounts convert to U-100 syringe units at two example concentrations. These are arithmetic conversions for reference, not a recommendation of any amount.
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 100 mcg (0.1 mg) | 0.04 mL | 4 units |
| 200 mcg (0.2 mg) | 0.08 mL | 8 units |
| 300 mcg (0.3 mg) | 0.12 mL | 12 units |
| 500 mcg (0.5 mg) | 0.2 mL | 20 units |
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 100 mcg (0.1 mg) | 0.1 mL | 10 units |
| 200 mcg (0.2 mg) | 0.2 mL | 20 units |
| 300 mcg (0.3 mg) | 0.3 mL | 30 units |
| 500 mcg (0.5 mg) | 0.5 mL | 50 units |
Mixing, color & storage tips
Very small amounts
A 100 mcg target at 2.5 mg/mL is 4 units — at the low end of what a U-100 syringe reads reliably. Reconstituting the same 5 mg vial with 5 mL instead gives 1 mg/mL, turning that 100 mcg into a 10-unit draw with much more margin for error.
Mixing without foam
Add the bacteriostatic water slowly down the inside wall of the vial and swirl rather than shake. DSIP is a short peptide and dissolves readily to a clear solution.
Storage
Keep the dry powder cold and dark. Refrigerate once reconstituted, keep it out of light, and plan around a limited usable window. Do not freeze a mixed vial.
A dilute vial goes further
Because DSIP amounts are small relative to the vial, a 5 mg vial yields a large number of draws. Choosing a more dilute mix does not waste material — it only changes how many units each draw reads as.

DSIP — frequently asked questions
What does this DSIP calculator tell me?
It converts your vial size, bacteriostatic water volume, and target amount into concentration in mg/mL, draw volume in mL, and the matching units on a U-100 insulin syringe. It is a measurement tool, not a recommendation.
Is the DSIP calculator free?
Yes — free, browser-based, and no signup is required.
How much bacteriostatic water do I add to a 5 mg DSIP vial?
A 5 mg vial with 2 mL makes 2.5 mg/mL, so 200 mcg is 8 units. Using 5 mL makes 1 mg/mL, so the same 200 mcg becomes 20 units — a larger, easier-to-read draw for small amounts.
How many units is 200 mcg of DSIP?
At 2.5 mg/mL it is 8 units (0.08 mL). At 1 mg/mL it is 20 units (0.2 mL). Units always depend on your exact concentration.
What does DSIP stand for?
Delta sleep-inducing peptide. It is a nonapeptide originally isolated from brain tissue and named for the delta-wave sleep activity observed in the early animal literature.
How long does a reconstituted DSIP vial last?
Refrigerate it, keep it dark, and plan around a limited usable window. Do not freeze a mixed vial; keep the dry powder cold for longer storage.

DSIP protocol & evidence
There is no established human dosing schedule for DSIP — the published work is animal or cell-culture research. The protocol page explains what that work does and does not show.
