Kisspeptin

What is it?

Kisspeptin is a neuropeptide involved in regulating reproductive hormones such as GnRH, LH, and FSH. It is commonly used to support testosterone production, fertility, libido, and hormonal balance.

Key Benefits

• Supports natural testosterone production

• Enhances fertility and reproductive hormone balance

• May improve libido and sexual function

• Supports metabolic health and body composition

• May help regulate hormonal signaling and recovery

How It Works

Kisspeptin stimulates:

• GnRH release from the hypothalamus

• LH and FSH production

• Testosterone, estrogen, and progesterone signaling

It is sometimes used as a gentler alternative to HCG for supporting the HPG axis.

Possible Side Effects

Usually uncommon:

• Headache

• Dizziness

• Sweating

• Hot flashes

• Diarrhea

• Appetite reduction

Women may experience temporary menstrual cycle changes.

• Best taken while fasted

• Effects may last up to 24 hours

• Overuse may lead to receptor desensitization

• Common frequency: every other day or 2x weekly
