Kisspeptin-10: dosing, reconstitution and evidence

A hypothalamic peptide that sits upstream of GnRH and drives the entire reproductive hormone cascade. Studied in humans for reproductive function and, interestingly, for sexual attraction responses.

Also known as Metastin fragment, KP-10

What people actually run

Used in the community, though the very short half-life makes the mechanism for intermittent dosing unclear.

This is accumulated community practice — years of real-world use across a large number of people, converging on numbers that work. It is not a controlled trial, and for most compounds here no such trial exists or is ever likely to. That makes this the most reliable dosing signal available, and it is a good deal better than guessing.

What to expect

Most people tolerate Kisspeptin-10 well. Here is what is worth knowing going in, so nothing catches you by surprise.

The ~4 minute half-life makes sustained effects from intermittent dosing implausible — worth knowing given how it is marketed. Continuous exposure downregulates the receptor and can suppress rather than stimulate the axis. Real human research exists but not for the uses it is sold for.

Reconstitution guide

Kisspeptin-10 ships as a lyophilised powder and gets mixed with bacteriostatic water before use. How much water you add sets the concentration, which sets how many syringe units make up each dose. One unit on a U-100 syringe is 0.01 mL — the tables below do the arithmetic for the vial sizes you are most likely to be holding.

6 units
10 mg vial + 3 mL BAC water = 3,333 mcg/mL — a 100 mcg dose = 3 units on a U-100 syringe. 5 mg vial + 3 mL = 1,667 mcg/mL — 100 mcg = 6 units.

Standard steps

  1. Inspect the vialConfirm the label and that the powder cake is intact. Do not use a cracked or compromised vial.
  2. Let it reach room temperatureSitting out for a few minutes reduces condensation inside the vial when the seal is broken.
  3. Disinfect both stoppersWipe the compound vial and the bacteriostatic water vial with a fresh alcohol swab and let them air-dry.
  4. Draw the bacteriostatic waterUse a sterile syringe to draw the volume you have chosen from the reconstitution table.
  5. Add the water down the vial wallInject slowly so it runs down the inside wall rather than spraying directly onto the powder. This limits foaming.
  6. Dissolve gentlySwirl or roll the vial between your hands until the cake dissolves. Never shake — agitation damages peptide bonds. The solution should end up clear.
  7. Label and refrigerateWrite the reconstitution date and concentration on the vial. Store at 2–8°C. Do not freeze.
