KPV reconstitution calculator.
Pre-filled with the 10 mg vial and 2 mL of bacteriostatic water the REGEN catalog reports for KPV. Every field is editable.
The numbers for a 10 mg KPV vial
Reconstituting a 10 mg vial with 2 mL of bacteriostatic water gives a concentration of 5 mg/mL. On a U-100 insulin syringe, where one unit is 0.01 mL, that puts 50 mcg in every unit drawn.
A 200 mcg dose at that concentration is 0.04 mL, which is 4 units on the syringe, and the vial holds about 50 of them.
Those are the values the calculator above opens with. The vial size and water volume are the amounts the REGEN catalog reports for KPV; change any field and the arithmetic follows.
What the research reports for KPV
Published protocols for KPV report 200–500 mcg, 1x daily. That is what the literature describes, not a recommendation. The calculator starts at the low end of it. The KPV reference page carries the evidence grade, the side-effect profile, and the primary sources behind that range.
KPV reconstitution chart for a 10 mg vial
The same 10 mg of KPV at four common water volumes. More water does not mean more compound, it spreads the same amount across a bigger volume, so the same dose is drawn to a higher number of units. That is usually the safer direction to be imprecise in: small errors on a longer draw matter proportionally less.
| Bacteriostatic water | Concentration | Per unit (U-100) | Units for 200 mcg |
|---|---|---|---|
| 1 mL | 10 mg/mL | 100 mcg | 2 units |
| 2 mL (catalog) | 5 mg/mL | 50 mcg | 4 units |
| 3 mL | 3.33 mg/mL | 33.3 mcg | 6 units |
| 5 mL | 2 mg/mL | 20 mcg | 10 units |
"Units" here means syringe graduations, not international units. They are unrelated measures that share a name, and conflating them is its own category of mistake. The reconstitution calculator explains the arithmetic behind these columns in full.
