Kisspeptin

Kisspeptin is a neuropeptide encoded by the KISS1 gene and is recognised in the literature as the master upstream regulator of the reproductive endocrine axis. The commonly used form is kisspeptin-10, the shortest C-terminal fragment that retains full receptor activity. Its discovery reshaped the understanding of how the brain initiates and sustains reproductive function.

Mechanism

Kisspeptin binds KISS1R (GPR54), a G-protein coupled receptor expressed on gonadotropin-releasing hormone neurons in the hypothalamus. Activation of these neurons triggers pulsatile GnRH release, which drives the pituitary secretion of luteinising hormone and follicle-stimulating hormone, and in turn the downstream production of endogenous sex steroids. Because it acts at the very top of the hypothalamic–pituitary–gonadal cascade, kisspeptin stimulates the body's own signalling architecture rather than substituting for it — the resulting hormone release remains physiologically pulsatile and subject to native feedback control.

What the studies show

• Robust, dose-dependent stimulation of LH and FSH release in human and animal studies
• Restoration of gonadotropin pulsatility in models of hypothalamic suppression
• Preservation of natural feedback regulation, distinguishing it from direct hormone administration
• Activation of limbic and paralimbic brain regions associated with sexual and emotional processing in neuroimaging studies
• Established role as a diagnostic probe of hypothalamic–pituitary function in clinical settings

Kisspeptin is central to the contemporary understanding of reproductive endocrinology, puberty onset, fertility and the neurobiology of attraction.

Frequently asked questions

How much does Kisspeptin cost in Egypt?
Prices for the single 10mg vial and the 4-vial kit are shown in Egyptian pounds on this page and kept up to date, so there is no need to message for a quote.

How is Kisspeptin different from taking hormones directly?
Kisspeptin works at the top of the chain, in the brain, and prompts the body to make its own hormones. Release stays in its natural rhythm and under the body’s own feedback control.

Is the packaging discreet?
Yes. Orders arrive in plain packaging with nothing on the outside indicating the contents.

How long does delivery take in Egypt?
Orders typically arrive within 3 to 5 days, delivered to every governorate, in insulated packaging with cold packs.
