DSIP reconstitution calculator

A 5 mg DSIP vial mixed with 2 mL of bacteriostatic water gives 2.5 mg/mL. A 200 mcg dose pulls 0.08 mL or 8 units. The vial covers 25 doses — about 5 weeks at the 5-nights-weekly cadence common in sleep protocols.

In the worked example below, a 5 mg vial of DSIP reconstituted with 2 mL of BAC water produces a concentration of 2.5 mg/mL. To draw the example dose of 0.2 mg from that vial you pull 0.08 mL — about 8 units on a standard insulin syringe. Change any input and the rest updates instantly so you can pre-plan a vial before you ever touch a needle.

Vial size, diluent volume, and dose are the three inputs that genuinely change the answer. Doses-per-vial is a derived output — it's the vial mg divided by the dose mg, rounded down. The most common edge case is a tiny dose: at very high concentration, a 0.1 mL draw is only a few units on the syringe, which is hard to read accurately. If your unit count drops below five, consider reconstituting the next vial with more BAC water so each dose covers a larger volume.

Reconstituting DSIP powder is a straightforward process that requires precision to ensure accurate dosing. You’ll be mixing the freeze-dried peptide with a sterile diluent, most commonly bacteriostatic water. Before you start, gather your supplies: the DSIP vial, your diluent, and an alcohol wipe. First, wipe the rubber stoppers on both vials. Then, you’ll draw your desired amount of diluent into a syringe. When you inject the diluent into the DSIP vial, aim the needle at the side of the glass wall, not directly onto the powder. Let the water run down the side gently. This prevents potential damage to the delicate peptide molecules. After adding the diluent, don't shake the vial. Instead, gently swirl or roll it between your hands until all the powder has completely dissolved into the solution.

Let's walk through a specific example to make the math crystal clear. Imagine you have a 5mg vial of DSIP and you decide to add 2mL of bacteriostatic water. Your final solution now has a concentration of 5mg of DSIP per 2mL of liquid. Since a standard 1mL insulin syringe has 100 units marked on it, your 2mL of liquid is equal to 200 units. To find the amount of DSIP per unit, you divide the total peptide amount by the total units: 5mg / 200 units = 0.025mg per unit. This is your dose concentration.

Now, let's say you want to track an example dose of 0.2mg. Using the concentration we just calculated, you can figure out how many units you need to draw into your syringe. The math is: Desired Dose (mg) / Concentration (mg per unit) = Dose in Units. In this case, it would be 0.2mg / 0.025mg per unit = 8 units. So, for a 0.2mg dose from a 5mg vial reconstituted with 2mL of water, you would carefully draw the solution up to the 8-unit mark on your insulin syringe. Getting this math right is fundamental to accurate and consistent tracking, which is why using a reliable calculator is always a good idea.
