Use this kisspeptin calculator to convert vial strength and BAC water volume into a precise draw. Kisspeptin is a reproductive-axis peptide dosed in micrograms; this page covers the math, not dosing decisions.
- Common vial examples
- 5 / 10 mg
- Example dose
- 100 mcg
- Common syringe
- U-100 insulin
- Last reviewed
Storage before and after reconstitution: Lyophilised 2–8°C; reconstituted vial refrigerated and protected from light.
Quick answers: Kisspeptin doses in units
With a 5 mg vial mixed with 2 mL of bacteriostatic water (2.5 mg/mL), on a U-100 insulin syringe:
- How many units is 100 mcg of kisspeptin?
- 4 units (0.04 mL)
- How many units is 200 mcg of kisspeptin?
- 8 units (0.08 mL)
- How many units is 300 mcg of kisspeptin?
- 12 units (0.12 mL)
Educational maths only, not a dose recommendation. Use the calculator above for your own vial, water volume and syringe.
Quick math example
A 5 mg vial mixed with 2 mL gives 2,500 mcg/mL. A 100 mcg dose is 0.04 mL, which equals 4 units on a U-100 syringe.
Kisspeptin reconstitution reference
U-100 units to draw for each common Kisspeptin 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 | 100 mcg | 200 mcg | 300 mcg |
|---|---|---|---|---|
| 5 mg | 2.5 mg/mL | 4 u(0.04 mL) | 8 u(0.08 mL) | 12 u(0.12 mL) |
| 10 mg | 5 mg/mL | 2 u(0.02 mL) | 4 u(0.04 mL) | 6 u(0.06 mL) |

Educational reference only — not a dose recommendation. Units assume a U-100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
Kisspeptin-10 dosage calculator: units for common doses
Most research vials are kisspeptin-10, the active 10-amino-acid fragment; the reconstitution maths is the same for any kisspeptin vial. Units on a U-100 syringe = dose (mcg) ÷ concentration (mcg/mL) × 100.
Kisspeptin doses are small, so a stronger mix gives very small draws. Adding more bacteriostatic water spreads the same dose across more readable units.
- 5 mg + 2 mL (2,500 mcg/mL): 100 mcg = 0.04 mL = 4 units; 200 mcg = 8 units; 300 mcg = 12 units
- 5 mg + 5 mL (1,000 mcg/mL): 100 mcg = 0.1 mL = 10 units; 200 mcg = 20 units
- 10 mg + 2 mL (5,000 mcg/mL): 100 mcg = 0.02 mL = 2 units — hard to read, add more water
How the kisspeptin calculation works
Kisspeptin is labelled in milligrams while doses are discussed in micrograms. Concentration is the vial total in mcg divided by water volume; the draw is your target divided by that concentration.
- 5 mg vial = 5,000 mcg total
- 5,000 mcg / 2 mL = 2,500 mcg per mL
- 100 mcg target = 0.04 mL draw
Kisspeptin 5 mg vial with 2 mL example
A 5 mg kisspeptin vial mixed with 2 mL gives 2.5 mg/mL, or 2,500 mcg/mL.
A 100 mcg dose is 0.04 mL — 4 units on a U-100 syringe. A 200 mcg dose is 0.08 mL, or 8 units.
- 5 mg / 2 mL = 2.5 mg/mL
- 100 mcg / 2,500 mcg per mL = 0.04 mL = 4 units
- 200 mcg / 2,500 mcg per mL = 0.08 mL = 8 units
Reconstitution and small draws
Kisspeptin dosing is not standardised, so confirm your target with your protocol. Because doses are small, pick a water volume that keeps the draw on readable unit marks, and re-run the calculator if you change the dose.
- Doses vary — confirm your target first
- More BAC water spreads small doses across more units
- A U-100 syringe suits sub-mg draws
