Start your Kisspeptin visit · from $158/moQuick answer: how do you calculate Kisspeptin units?
To calculate kisspeptin units, divide the milligrams in the vial by the millilitres of liquid to get the concentration, divide your prescribed dose in milligrams by that concentration to get the volume, then multiply the volume in mL by 100 for units on a U-100 syringe. Kisspeptin-10 doses are in micrograms, so a dilute vial keeps the draw readable. Example: a 5 mg vial with 5 mL of bacteriostatic water is 1 mg/mL, so if your prescription says 70 mcg (0.07 mg), you draw 0.07 mL, which is 7 units.
Kisspeptin dosing chart in units
Units to draw on a U-100 syringe for common Kisspeptin vial sizes and water volumes. Find your vial on the left and read across to the dose on your prescription. This is a conversion table, not a dosing recommendation; a dash means the dose is larger than the vial.
| Vial | Water | mg/mL | 50 mcg | 70 mcg | 100 mcg | 150 mcg | 250 mcg |
|---|---|---|---|---|---|---|---|
| 5 mg | 1 mL | 5 | 1 | 1.4 | 2 | 3 | 5 |

Pre-mixed kisspeptin: reading the pharmacy label
Kisspeptin calculators online assume a 5 mg or 10 mg freeze-dried vial of kisspeptin-10 mixed with 1 or 2 mL, which gives 2.5 to 10 mg/mL and draws of 1 to 4 units for a microgram dose. Several of those pages also contradict their own tables. A compounding pharmacy prescription usually arrives as a liquid at a lower strength, with the concentration printed on the label in mg/mL or mcg/mL; 500 mcg/mL is 0.5 mg/mL.
Divide your prescribed dose in mg by the label concentration to get mL, then multiply by 100 for units: 70 mcg (0.07 mg) from a 0.5 mg/mL vial is 0.14 mL, or 14 units. Switch the calculator above to Pre-mixed vial and type the label strength.
Check the name on the label as well as the strength. Kisspeptin-10 is the ten-amino-acid fragment used in compounded protocols; the full-length kisspeptin-54 is a different molecule, and a prescription written for one should not be drawn from a vial of the other without asking the pharmacy.

Use the volume your pharmacy or prescriber specifies. The water changes only the concentration, never the amount of Kisspeptin in the vial: more water means more units for the same dose.

| 2 mL | 2.5 | 25 |

When kisspeptin units are too small to read
Kisspeptin draws are short. A 10 mg vial mixed with 2 mL is 5 mg/mL, so 70 mcg is 1.4 units and 100 mcg is 2 units; the calculator flags draws under 2 units because a half-unit error at that size is a large fraction of the dose.
More water for the same vial fixes it: 5 mg in 5 mL is 1 mg/mL, so 70 mcg becomes 7 units. Whether that is appropriate for your vial is a question for your pharmacist or prescriber; do not change the amount of water on your own. A 0.3 mL syringe, marked every unit or half unit, is the right tool for draws under 30 units.

Kisspeptin calculator FAQ
How many units of kisspeptin do I draw?
Units = dose (mg) ÷ concentration (mg/mL) × 100. For a 5 mg vial mixed with 5 mL (1 mg/mL), a prescription of 70 mcg is 0.07 mL, or 7 units on a U-100 syringe. The dose itself comes from your prescription.
Is the math different for kisspeptin-10 and kisspeptin-54?
The formula is the same, but they are different molecules with different prescriptions, so never draw one from a vial of the other. Compounded protocols almost always use kisspeptin-10; confirm the label names the same form as your prescription before you calculate.
How much bacteriostatic water do I add to 5 mg of kisspeptin?
Use the volume your pharmacy or prescriber specifies. The water does not change the amount of kisspeptin, only the concentration: 1 mL makes 5 mg/mL (50 mcg per unit), 2 mL makes 2.5 mg/mL (25 mcg per unit) and 5 mL makes 1 mg/mL (10 mcg per unit). Peptides.build prescriptions arrive pre-mixed, so patients never add water.
Why is my kisspeptin draw only 1 or 2 units?
Because a 5 or 10 mg vial is large relative to a microgram dose. At 5 mg/mL every unit carries 50 mcg, so small prescriptions land at 1 to 2 units. A more dilute vial, or a pre-mixed pharmacy vial at 0.5 or 1 mg/mL, gives a longer draw for the same dose. Ask the pharmacy rather than adding water on your own.
My kisspeptin vial came pre-mixed. How do I convert my dose to units?
Read the concentration on the pharmacy label, for example 0.5 mg/mL (500 mcg/mL). Divide your prescribed dose in mg by it to get mL, then multiply by 100: 0.07 mg ÷ 0.5 mg/mL = 0.14 mL = 14 units. Choose Pre-mixed vial in the calculator to do this automatically.
How should kisspeptin be stored once mixed?
Follow the storage line on the pharmacy label. Reconstituted peptides are typically kept refrigerated, not frozen, and used before the beyond-use date. Do not use a vial that looks cloudy or has particles; contact the pharmacy.
Is kisspeptin FDA-approved?
No. Kisspeptin is not FDA-approved for any use, and compounded medications are not FDA-approved. When it is prescribed, a licensed provider decides whether it is appropriate for the individual patient, and because it acts on hormonal signaling that review usually includes labs.
Is kisspeptin allowed in competitive sport?
No. The World Anti-Doping Agency Prohibited List names kisspeptin and its agonist analogues under S2 (peptide hormones and related substances), prohibited at all times; the entry is written for male athletes. Drug-tested athletes of any sex should check with their governing body.
Does this calculator tell me how much kisspeptin to take?
No. It performs arithmetic only and does not recommend a dose or schedule. The dose, timing and vial strength come from your prescription and pharmacy label.
