DSIP
Five milligrams, hundreds of doses.
Delta sleep-inducing peptide is sold in 5 mg vials and dosed in the low hundreds of micrograms, so one vial holds far more than most storage windows allow you to use.

The science
When the vial outlasts the solution
01
DSIP is a short peptide first isolated from rabbit brain tissue in the 1970s and named for the effect observed in that early work. It is supplied as a lyophilised powder, most often in 5 mg vials.
02
The arithmetic itself is unremarkable. A 5 mg vial in 2 ml is 2.5 mg per ml, so a 250 mcg dose is 0.1 ml, which is 10 units on a U-100 barrel. That is squarely in the readable range and needs no special handling.
03
The problem is quantity. A 5 mg vial contains twenty doses of 250 mcg. Used nightly that is under three weeks, which fits most storage windows. Used a few times a week it is two months or more, which does not, and the surplus has to be discarded rather than kept.
04
That makes the vial expiry question more pressing for DSIP than the measurement question. Working out how many doses fit inside your storage window before you reconstitute tells you whether to mix the whole vial or whether a smaller working volume makes more sense.

2, 5 and 10 mg vials by water volume
DSIP doses sit in a comfortable part of the barrel at most reconstitutions. The harder question is how much of the vial you can realistically use.

A dot marks a combination that falls under two units or overflows a 100-unit barrel. Both are hard to measure accurately, so they are worth avoiding rather than eyeballing.
Regulatory status
DSIP has no approved use
DSIP has not been approved for human use by the FDA or any comparable regulator. Despite being first described in the 1970s, it has never reached approval for any indication, so there is no label and no official dose.
It is covered by the World Anti-Doping Agency's S0 category, which captures any pharmacological substance with no current approval from any governmental health authority, so it is prohibited in tested sport at all times.
The name describes an effect observed in early animal work, not an established clinical outcome in people. Treating the name as a claim about what the compound does is a mistake worth avoiding.
FAQ
Common questions
How many units is 250 mcg of DSIP?
From a 5 mg vial reconstituted with 2 ml, the concentration is 2.5 mg per ml, so 250 mcg is 0.1 ml, which is exactly 10 units on a U-100 syringe. That round figure is one reason 2 ml is a common choice for a 5 mg vial.
How much bacteriostatic water for a 5 mg DSIP vial?
Two millilitres gives 2.5 mg per ml, which makes a 250 mcg dose exactly 10 units and keeps the microgram to unit conversion easy to check mentally. Anything from 1 to 3 ml keeps typical doses in a readable range.
How long will a 5 mg vial of DSIP last?
Twenty doses at 250 mcg. Whether that is three weeks or three months depends entirely on your frequency, and the storage window does not extend to match. Work out the dose count against your window before reconstituting rather than after.
What does DSIP stand for?
Delta sleep-inducing peptide, named after the observation that prompted its original isolation in the 1970s. The name describes the context of its discovery rather than an established clinical effect, and no regulator has approved it for any indication.
Is DSIP approved for human use?
No. DSIP has not been approved by the FDA or any comparable regulator. There is no prescribing information, no approved indication and no official dose. It is sold as a research chemical, and the calculator here performs arithmetic on figures you provide rather than suggesting one.

Every tool here is stateless by design. What it cannot do is remember that your vial was mixed eleven days ago, or that a step-up is due this week.
This tool performs arithmetic on figures you enter, or presents a manufacturer-published schedule. It does not know your protocol, will never suggest a dose, and is not medical advice. Dosing decisions belong with a qualified prescriber.
