How the units are worked out

Your vial holds a fixed amount of peptide. The water you add sets the concentration (how much peptide sits in each millilitre). The concentration then decides how much liquid carries your dose.

Three steps, in order:

Concentration (mcg/mL) = peptide in the vial (mcg) divided by water added (mL).
Volume (mL) = your dose (mcg) divided by the concentration (mcg/mL).
Units to draw = volume (mL) multiplied by 100.

That last step is the syringe, not the peptide. A U-100 insulin syringe is marked so 100 units hold 1 mL, so 0.1 mL reads as 10 units.

A worked example

These are the numbers in the calculator above, worked through: 10 mg + 2 mL = 5,000 mcg/mL. 100 mcg = 0.02 mL = 2 units on a 0.3 mL syringe.

Mixing and storage

Run the water down the inside wall of the vial and let the powder dissolve on its own. Never shake it. Label the vial with the compound, the total mass, the water you added, the concentration and the date. A sealed freeze-dried vial keeps 12 to 24 months in the fridge at 2 to 8°C. Once mixed with preserved water, such as bacteriostatic water, that drops to roughly 28 days refrigerated. Keep it at the back of the fridge, away from light and away from the door's temperature swings.

Questions

Does kisspeptin-10 raise testosterone?

In men, yes, in the short term. In a hospital study, kisspeptin-10 raised LH quickly, and a continuous infusion raised testosterone as well. That is the whole point of the peptide. It sits above the reproductive axis and switches it on. But those were supervised infusions lasting hours. Nobody has shown that repeated self-injection gives a lasting testosterone gain. One kisspeptin analogue did the opposite when it was given non stop.

Does kisspeptin-10 improve libido?

The sexual desire studies did not use kisspeptin-10. Imperial College London ran randomised trials in men and in women with hypoactive sexual desire disorder. Both used kisspeptin-54, the longer form. In men, kisspeptin-54 changed sexual brain activity and increased physical arousal. In women it changed how the brain processed erotic and attraction cues. Whether the ten amino acid version does the same thing in people has not been tested.

Is kisspeptin-10 the same thing as kisspeptin-54?

No. They come from the same gene and act on the same receptor, but they are different peptides. Kisspeptin-54 is the full chain your body makes. Kisspeptin-10 is the last ten amino acids of that chain. In lab cells the short tail is as potent as the whole peptide. In people the two have been tested in different studies, for different questions, so results from one do not automatically carry over.

Does it work the same way in women and in men?

No. One study gave kisspeptin-10 to both men and women. The men showed a clear rise in LH and FSH. The women responded near ovulation, but showed no gonadotropin rise at all during the early follicular phase. So where a woman sits in her cycle changes the answer completely. That is real biology, not a technique problem, and it makes the effect in women much harder to predict.

Is kisspeptin-10 legal?

It is not an approved medicine. The FDA has placed it in category 2 of its bulk drug substances list under section 503A. That means the agency has flagged potential significant safety risks, and says it lacks the information to know whether kisspeptin-10 would harm people. Nothing about that position has changed. An advisory committee vote is advice, not a rule change, and the FDA has stated these substances were never lawfully compounded under 503A.

What should I ask a doctor about it?

Ask what your LH, FSH, testosterone or oestradiol actually look like now, and what is driving the symptom you want fixed. Ask whether an approved treatment already exists for that problem. Ask what a hormone panel would show before and after anything you take. If low desire is the issue, ask about the causes a clinic can treat today. The trials that showed a sexual effect used a different peptide, and they are not a treatment yet.
