About Kisspeptin
Kisspeptins are peptides encoded by the KISS1 gene. Kisspeptin-10, the 10-amino-acid C-terminal fragment (Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH2), is the form most often supplied for research. Biogenesis Labs supplies kisspeptin as lyophilized powder in 10 mg vials, for laboratory research use only.
Research-grade vials: Kisspeptin 10 mg. Every batch is independently tested — see the Certificates of Analysis.
How to calculate Kisspeptin concentration
concentration (mg/mL) = kisspeptin in vial (mg) ÷ diluent volume (mL)
- A 10 mg Kisspeptin vial with 2 mL of bacteriostatic water is 5.00 mg/mL (5,000 mcg/mL).
- On a U-100 syringe, 100 units = 1 mL, so each unit holds 50.0 mcg.
- Use 3 mL instead and the same vial reads 3.33 mg/mL, or 33.3 mcg per unit. More diluent lowers the concentration; the kisspeptin in the vial does not change.
For U-40 syringes (40 units = 1 mL), divide mcg/mL by 40 instead of 100. The calculator above switches between both scales.

Kisspeptin 10 mg vial
| Diluent | Concentration | mcg / mL | Per U-100 unit | In 10 units | U-100 units per 1 mg |
|---|---|---|---|---|---|
| 1 mL | 10.00 mg/mL | 10,000 | 100.0 mcg | 1.00 mg | 10.00 |
| 1.5 mL | 6.67 mg/mL | 6,667 | 66.7 mcg | 0.67 mg | 15.00 |
| 2 mL | 5.00 mg/mL | 5,000 | 50.0 mcg | 0.50 mg | 20.00 |
| 2.5 mL | 4.00 mg/mL | 4,000 | 40.0 mcg | 0.40 mg | 25.00 |
| 3 mL | 3.33 mg/mL | 3,333 | 33.3 mcg | 0.33 mg | 30.00 |
| 4 mL | 2.50 mg/mL | 2,500 | 25.0 mcg | 0.25 mg | 40.00 |
| 5 mL | 2.00 mg/mL | 2,000 | 20.0 mcg | 0.20 mg | 50.00 |
Values are rounded. Figures describe solution concentration only and are not recommendations.
Reconstituting and storing a Kisspeptin vial
Let the sealed vial reach room temperature, swab both stoppers, and run the diluent slowly down the inside wall of the vial rather than onto the powder. Swirl gently until dissolved — don't shake — and label the vial with the concentration and date. Reconstituted solutions are commonly kept refrigerated at 2–8 °C and protected from light. The full step-by-step guide, syringe-scale explainer and BAC vs. sterile water comparison are on the main Peptide Calculator page.
Kisspeptin calculator FAQ
What concentration does a 10 mg Kisspeptin vial with 3 mL of bacteriostatic water give?
3.33 mg/mL (3,333 mcg/mL). On a U-100 syringe that is 33.3 mcg per unit, and 10 units hold 0.33 mg.
What concentration does a 10 mg Kisspeptin vial with 2 mL give?
5.00 mg/mL, or 50.0 mcg per unit on a U-100 syringe.
How many U-100 units contain 1 mg of Kisspeptin?
It depends on the concentration: units per mg = 100 ÷ concentration in mg/mL. At 3.33 mg/mL (10 mg in 3 mL) 1 mg is in 30.00 units; at 5.00 mg/mL (10 mg in 2 mL) it is in 20.00 units.
How much bacteriostatic water should be added to a Kisspeptin vial?
There is no single correct volume. The volume comes from your own research protocol; the calculator and chart show the concentration each volume produces. Only add a volume your vial can hold.
Does the kisspeptin form change the calculation?
No. Concentration depends only on the mg in the vial and the mL of diluent, whichever kisspeptin form is on the label.
Does this Kisspeptin calculator provide dosing guidance?
No. It performs concentration and unit-conversion math only. All Biogenesis Labs products are supplied for laboratory research use only and are not for human consumption.
