In this example, 2 mL of bacteriostatic water in a 10 mg DSIP vial gives 5.00 mg/mL. An example 250 mcg amount is then 5.0 units on a U-100 syringe.
This example lands on a syringe line. More water makes a weaker mix and a bigger draw. Less water makes a stronger mix and a smaller one. The amount of DSIP stays the same. Use the diluent and volume specified for your product; the arithmetic alone does not choose them.
| Water added | Concentration | Per U-100 unit | Example: 250 mcg = |
|---|---|---|---|
| 2 mL | 5.00 mg/mL | 50 mcg | 5.0 units |
| 3 mL | 3.33 mg/mL | 33.33 mcg | 7.5 units |
Straight arithmetic: concentration = 10 mg ÷ liquid volume, and 1 U-100 unit = 0.01 mL. The example column shows the math at 250 mcg; it is not a dose recommendation.
The table compares possible concentrations; it does not establish which diluent or volume suits your product. Follow its dispensing instructions.
“Hard to measure” means the example draw is below two U-100 units. “Won’t fit” means it exceeds this syringe’s capacity.
DSIP stands for delta sleep-inducing peptide. It is nine amino acids long, and it was recovered in 1977 from the blood of rabbits put into deep sleep electrically.
The larger DSIP vial doubles the doses and halves the draw. At the smaller water volume that puts one dose at five units, where a single mark is a fifth of it.
Doubling the vial at the same water doubles the strength, so the same amount takes half the liquid and half the marks. The count of doses goes up and the quality of the reading goes down.
On this page that trade is unusually stark. The draws were already small on the smaller vial.
Of the two listed, one gives a whole number of units. The other leaves the plunger on a half-mark the barrel never prints.
Neither option is easy to measure: one is very small, while the other falls between syringe lines. Both exact results are shown without recommending one.
The vial divides into forty worked amounts, but no product-specific storage limit is assigned to this example.
The human studies behind this peptide date from the 1980s. They put it into a vein at amounts scaled to body weight, and none of them reached an approval. The count below is arithmetic on a vial, not a course anyone has run.
The calculator lets you enter your product’s vial strength and mixing volume, then shows the arithmetic for your syringe.
