Use this KPV calculator to turn your vial strength and bacteriostatic water volume into an exact draw in mL and syringe units. KPV is a three-amino-acid fragment of alpha-MSH (lysine-proline-valine) dosed in micrograms; it is a research peptide, not an approved medicine, and this page covers the maths only.

Quick math example
A 10 mg vial mixed with 2 mL gives 5 mg/mL, or 5,000 mcg/mL. A 500 mcg dose is 0.1 mL, which equals 10 units on a U-100 syringe.
KPV reconstitution reference
U-100 units to draw for each common KPV dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 200 mcg | 250 mcg | 500 mcg |
|---|---|---|---|---|
| 5 mg | 2.5 mg/mL | 8 u(0.08 mL) | 10 u(0.1 mL) | 20 u(0.2 mL) |
| 10 mg | 5 mg/mL | 4 u(0.04 mL) | 5 u(0.05 mL) | 10 u(0.1 mL) |

KPV dosage chart: units for 5 mg and 10 mg vials
KPV doses are written in micrograms. The injectable amounts most often cited in community protocols are 200 to 500 mcg once or twice a day. The research behind KPV is in animal models of gut and skin inflammation, with no completed human efficacy trials, so this page does not recommend a dose. The chart shows what each amount looks like on a U-100 syringe.
The same dose is a different number of units at each concentration: 250 mcg is 10 units from a 5 mg vial in 2 mL, 7.5 units from a 10 mg vial in 3 mL and 5 units from a 10 mg vial in 2 mL.
- 5 mg + 2 mL (2,500 mcg/mL): 250 mcg = 10 units · 500 mcg = 20 units
- 10 mg + 2 mL (5,000 mcg/mL): 250 mcg = 5 units · 500 mcg = 10 units
- A 10 mg vial holds twenty 500 mcg doses

Educational reference only — not a dose recommendation. Units assume a U-100 insulin syringe (100 units = 1 mL on U-100); “per vial” is how many of that dose the vial holds, before the small dead-space loss on each draw. Confirm against your own vial, diluent, and clinician or pharmacy instructions.
How the KPV calculation works
KPV vials are labelled in milligrams while doses are written in micrograms, so the first step is always mg to mcg. The calculator then divides by your water volume for the concentration and divides your dose by that concentration.
- 10 mg vial = 10,000 mcg total
- 10,000 mcg / 2 mL = 5,000 mcg per mL
- 500 mcg target = 0.1 mL draw = 10 units
KPV 10 mg vial with 2 mL example
A 10 mg KPV vial mixed with 2 mL gives 5 mg/mL, or 5,000 mcg/mL. A 500 mcg dose is 0.1 mL (10 units) and a 250 mcg dose is 0.05 mL (5 units).
If 5 units is hard to read on your syringe, 3 mL of water lowers the concentration to about 3,333 mcg/mL and moves 250 mcg to 7.5 units.
- 10 mg / 2 mL = 5 mg/mL
- 500 mcg / 5,000 mcg per mL = 0.1 mL = 10 U-100 units
- 250 mcg / 5,000 mcg per mL = 0.05 mL = 5 U-100 units
KPV 10 mg vial: units per dose (2 mL BAC water)
U-100 units to draw for each common KPV dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.

KPV in the KLOW blend
KPV is also sold inside the KLOW blend, alongside GHK-Cu, BPC-157 and TB-500, usually as 10 mg of an 80 mg vial. In a blend every draw contains all four peptides in a fixed ratio, so a KPV dose from a KLOW vial has to be calculated from the blend total, not from this single-peptide calculator.

Injectable vs oral KPV
KPV is sold both as lyophilised vials for injection and as oral capsules aimed at the gut, following animal studies of oral delivery. Capsules come pre-dosed and need no reconstitution. This calculator is for the vial form, where you add bacteriostatic water and measure each dose yourself.
