KPV peptide calculator
A 5 mg KPV vial mixed with 2 ml of bacteriostatic water holds 2.5 mg/ml. A 500 mcg dose is 0.20 ml — 20 units on a U-100 insulin syringe — and the vial holds 10 doses of that size.
KPV dosage chart: units to draw
Units on a U-100 insulin syringe (100 units = 1 ml) for KPV doses from 250 mcg to 1 mg, by how much bacteriostatic water is in a 5 mg vial. The highlighted row is the 500 mcg dose used above.
| Dose | 1 ml water 5 mg/ml | 2 ml water 2.5 mg/ml | 3 ml water 1.67 mg/ml | Doses per vial |
|---|---|---|---|---|
| 250 mcg | 5 u 0.050 ml | 10 u 0.10 ml | 15 u 0.15 ml | 20 |
| 500 mcg | 10 u 0.10 ml | 20 u 0.20 ml | 30 u 0.30 ml | 10 |
| 750 mcg | 15 u 0.15 ml | 30 u 0.30 ml | 45 u 0.45 ml | 6 |
| 1 mg | 20 u 0.20 ml | 40 u 0.40 ml | 60 u 0.60 ml | 5 |
A 20-unit draw fits comfortably on a 0.3 ml insulin syringe (30-unit capacity), whose 1-unit (often half-unit) markings are easier to read than the 2-unit ticks on a 1 ml syringe.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the KPV guide for sources.
How to reconstitute KPV
- Wipe both vial stoppers with a fresh alcohol swab and let them dry.
- Draw 2 ml of bacteriostatic water into a syringe.
- Insert the needle at an angle into the KPV vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
- Do not shake. Gently swirl the vial until the peptide fully dissolves.
- Storage for KPV: Lyophilized: refrigerated. Reconstituted: refrigerated, use within 28 days.
- For a 500 mcg dose, draw to the 20-unit mark (0.20 ml) on a U-100 insulin syringe.
About KPV
KPV is the C-terminal tripeptide (Lys-Pro-Val) of alpha-melanocyte-stimulating hormone (α-MSH). Research focuses on its anti-inflammatory properties in gastrointestinal, skin, and systemic inflammation models.
Half-life: Approximately 1–2 hours
Typical dose range: 500–1000 mcg daily (subcutaneous); oral protocols also used
Class: Anti-inflammatory tripeptide (α-MSH 11-13)
Regulatory status: Not FDA approved. Research use only in the US.

Need a different unit or a different question? The peptide dose converter moves a dose between mcg, mg and IU, and the KPV half-life chart shows how concentration accumulates across a dosing cadence. Loading KPV into a reusable 3 ml pen instead of drawing it with a syringe? The peptide pen calculator turns the same vial into mcg per click and clicks to dial. All of them are listed on the free peptide tools page.
KPV calculator FAQ
Is this a KPV peptide calculator or a reconstitution calculator?
Both. This KPV calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
How much bacteriostatic water for a 5 mg KPV vial?
This page is pre-filled with 2 ml of bacteriostatic water for a 5 mg KPV vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 500 mcg KPV dose?
20 units on a U-100 insulin syringe, when a 5 mg vial is mixed with 2 ml of bacteriostatic water (2.5 mg/ml). That is 0.20 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
How many doses are in a 5 mg KPV vial?
10 doses of 500 mcg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
Does this KPV dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether KPV is appropriate are clinical decisions that should be made with a licensed healthcare professional.
