DSIP dosage calculator
DSIP vials are commonly labelled 2 mg, 5 mg. This calculator divides the vial mass by the diluent volume you enter to show concentration, then converts your own target amount into millilitres and syringe units. It states no dose, chooses no amount and stores nothing.
This page is a calculation tool. The amounts you enter are values you decided; this page states no dose and gives no medical advice.
DSIP vial concentration grid
This table answers one arithmetic question: what concentration results when a labelled vial mass is divided by a measured diluent volume? It does not select either value.
| Vial mass | Diluent | Concentration | Same concentration |
|---|---|---|---|
| 2 mg | 0.5 mL | 4,000 mcg/mL | 4 mg/mL |
| 2 mg | 1 mL | 2,000 mcg/mL | 2 mg/mL |
| 2 mg | 1.5 mL | 1,333.33 mcg/mL | 1.333 mg/mL |
| 2 mg | 2 mL | 1,000 mcg/mL | 1 mg/mL |
| 2 mg | 2.5 mL | 800 mcg/mL | 0.8 mg/mL |
| 2 mg | 3 mL | 666.67 mcg/mL | 0.667 mg/mL |
| 2 mg | 5 mL | 400 mcg/mL | 0.4 mg/mL |
| 5 mg | 0.5 mL | 10,000 mcg/mL | 10 mg/mL |
| 5 mg | 1 mL | 5,000 mcg/mL | 5 mg/mL |
| 5 mg | 1.5 mL | 3,333.33 mcg/mL | 3.333 mg/mL |
| 5 mg | 2 mL | 2,500 mcg/mL | 2.5 mg/mL |
| 5 mg | 2.5 mL | 2,000 mcg/mL | 2 mg/mL |
| 5 mg | 3 mL | 1,666.67 mcg/mL | 1.667 mg/mL |
| 5 mg | 5 mL | 1,000 mcg/mL | 1 mg/mL |
DSIP physical-property record
DSIP molecular record
PubChem lists delta sleep-inducing peptide with formula C35H48N10O15 and molecular weight 848.8 g/mol. Cayman supplies a trifluoroacetate salt with a higher formula mass for that catalog material. The abbreviation DSIP should therefore be expanded in the record, and the TFA or free-form basis should be retained whenever molecular weight or peptide content is compared. Sources: PubChem: delta sleep-inducing peptide compound record · Cayman Chemical: DSIP TFA specification.
DMSO solubility is a laboratory-only context
Cayman reports DMSO solubility at 5 mg/mL and storage at -20 C for its DSIP TFA reference product. The solvent name is essential to the meaning of the result. This calculator does not treat DMSO as a selected diluent and does not use the reported concentration as a preset. It calculates only from the measured liquid value entered for the recorded item. Sources: Cayman Chemical: DSIP TFA specification.
Abbreviation control prevents source mixing
A DSIP record should keep the expanded compound name, sequence or catalog identifier, salt form, lot and purity statement. That detail helps distinguish the peptide from unrelated abbreviations and exposes whether a technical source refers to the same chemical material. PubChem anchors the peptide identity; Cayman anchors one TFA product. Neither can authenticate another supplier's vial.

Arithmetic without a solvent recommendation
The page divides labelled mass by measured volume and converts the user's own target into volume markings. It does not choose DMSO, water or another liquid based on the technical sheet. It also does not infer stability, sterility or medical suitability. The cited physical facts are kept next to the DSIP-specific content while the calculator states no dose and gives no protocol.

How to use the calculator
- Read the total mass from your own vial label and enter it in milligrams.
- Enter the diluent volume you actually measured, not an intended or remembered value.
- Enter your own target amount and select the calibration printed on your syringe barrel.
- Record the concentration with the result so the syringe-unit figure remains interpretable later.
Source and identity record
Use the compound reference page and these external database searches when checking identity: PubMed literature search for DSIP · PubChem compound database · PubChem: delta sleep-inducing peptide compound record · Cayman Chemical: DSIP TFA specification. A database record does not authenticate a vial.
Frequently asked questions
How much bacteriostatic water for a 2 mg DSIP vial?
This calculator does not choose a diluent volume. Enter the volume you decided to add to the 2 mg vial and it will show the resulting concentration. The page supplies arithmetic, not an instruction.
How much bacteriostatic water for a 5 mg DSIP vial?
There is no universal volume selected by this page. Use the value you measured or were instructed to use; the calculator then divides the 5 mg label mass by that volume.
Does the DSIP calculator recommend a dose?
No. The target amount is always entered by the user. The tool provides no starting amount, maximum amount, progression, frequency or schedule.
Why does the syringe calibration matter?
A syringe unit is a volume marking. U-100, U-50 and U-40 barrels use different numbers of units per millilitre, so the same solution volume produces different markings.
