KPV Reconstitution & Dosage Calculator
This free KPV calculator turns your vial size, the bacteriostatic water you add, and your target amount into a concentration, a draw volume, and the exact units on a U-100 insulin syringe. KPV is a three-amino-acid fragment of alpha-MSH studied for its anti-inflammatory signalling, and it is handled in microgram to low-milligram amounts. This is a measurement tool — it does not recommend an amount.

Quick summary
- Converts vial size (mg), bacteriostatic water (mL), and a microgram amount into concentration, draw volume, and U-100 units.
- Reference math for the 10 mg vial KPV is supplied in, standalone or as the fourth component of a KLOW blend.
- Educational research and measurement tool only — it does not diagnose, treat, or recommend an amount.
What this KPV calculator does
This calculator does one job well: it turns your vial size, the amount of bacteriostatic water you add, and your target amount into a concentration (mg/mL), a draw volume (mL), and the matching units on a U-100 insulin syringe. Change any input and the result updates instantly.
KPV ships as a freeze-dried powder. Before it can be measured into a syringe it has to be reconstituted — dissolved in bacteriostatic water. How much water you add sets the concentration, and the concentration sets how many units each amount works out to. The presets above cover the most common KPV vial setups; use the custom fields for anything else.
How to use the KPV calculator
Pick your syringe
Choose the U-100 insulin syringe you'll draw with. Smaller syringes (0.3 mL / 30u) have finer lines, which helps when the draw is small.
Enter your vial and water
Set the milligrams in your KPV vial and the bacteriostatic water you added. Together these set the concentration.
Set your target amount
Toggle mg or mcg and pick (or type) the amount you're measuring for. The calculator does the conversion for you.
Read the draw
The result panel shows concentration, draw volume, and the exact U-100 units to pull, plus how many doses your vial contains.
KPV reconstitution math, explained
The math is short. Concentration = vial size ÷ bacteriostatic water. Draw volume = target amount ÷ concentration. Units = draw volume × 100 (a U-100 syringe reads 100 units per mL). The table below shows common KPV setups and the units for a 1 mg amount at each.
| Vial size | Bac water | Concentration | Units per 1 mg |
|---|---|---|---|
| 10 mg | 1.0 mL | 10 mg/mL | 10 units |
| 10 mg | 2.0 mL | 5 mg/mL | 20 units |
| 10 mg | 3.0 mL | 3.33 mg/mL | 30 units |
| 10 mg | 5.0 mL | 2 mg/mL | 50 units |
| 5 mg | 2.0 mL | 2.5 mg/mL | 40 units |
KPV amount-to-units reference
How common amounts convert to U-100 syringe units at two example concentrations. These are arithmetic conversions for reference, not a recommendation of any amount.
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 200 mcg (0.2 mg) | 0.04 mL | 4 units |
| 250 mcg (0.25 mg) | 0.05 mL | 5 units |
| 500 mcg (0.5 mg) | 0.1 mL | 10 units |
| 1000 mcg (1 mg) | 0.2 mL | 20 units |
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 200 mcg (0.2 mg) | 0.1 mL | 10 units |
| 250 mcg (0.25 mg) | 0.125 mL | 12.5 units |
| 500 mcg (0.5 mg) | 0.25 mL | 25 units |
| 1000 mcg (1 mg) | 0.5 mL | 50 units |
Mixing, color & storage tips
A wide amount range
KPV appears in the literature across a broad span, from a couple of hundred micrograms to a full milligram. At 5 mg/mL that range spans 4 to 20 units, so the same vial can produce comfortable draws across the whole range without re-mixing.
Mixing without foam
Run the bacteriostatic water down the inside wall of the vial and swirl gently until the powder is fully dissolved. Do not shake. KPV is a short tripeptide and dissolves readily to a clear solution.
Storage
Keep the dry powder cold and dark. Refrigerate once reconstituted, keep it out of light, and plan around a limited usable window. Do not freeze a mixed vial.
Standalone vs in a KLOW blend
KPV is the component that distinguishes a KLOW blend from a GLOW blend. If your vial is a blend rather than KPV alone, one draw delivers all four components in a fixed ratio — use the KLOW blend calculator instead of this page.

KPV — frequently asked questions
What does this KPV calculator tell me?
It converts your vial size, bacteriostatic water volume, and target amount into concentration in mg/mL, draw volume in mL, and the matching units on a U-100 insulin syringe. It is a measurement tool, not a recommendation.
Is the KPV calculator free?
Yes — free, browser-based, and no signup is required.
How much bacteriostatic water do I add to a 10 mg KPV vial?
A 10 mg vial with 2 mL makes 5 mg/mL, which turns a 500 mcg target into a 10-unit draw. Using 5 mL instead makes 2 mg/mL, so the same 500 mcg becomes 25 units. Both are readable; the dilute mix is more forgiving at the low end.
How many units is 500 mcg of KPV?
At 5 mg/mL it is 10 units (0.1 mL). At 2 mg/mL it is 25 units (0.25 mL). Units always depend on your exact concentration.
What is the difference between KPV and GLOW or KLOW?
KPV is a single tripeptide. KLOW is a four-component blend — BPC-157, GHK-Cu, TB-500 and KPV in one vial — and GLOW is the same blend without KPV. A blend vial needs the blend calculator, because one draw carries every component at once.
How long does a reconstituted KPV vial last?
Refrigerate it, keep it dark, and plan around a limited usable window. Do not freeze a mixed vial; keep the dry powder cold for longer storage.

KPV protocol & evidence
There is no established human dosing schedule for KPV — the published work is animal or cell-culture research. The protocol page explains what that work does and does not show.
