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.
Reconstitution reference
U100 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 U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
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
