How should Kisspeptin be stored?

In lyophilized powder form, Kisspeptin is stable at room temperature short-term but should be refrigerated (2–8°C) for longer storage and kept away from light and moisture. Once reconstituted, keep refrigerated and use within 30 days. Avoid freeze-thaw cycles.

Is Kisspeptin approved by the FDA?

No. Kisspeptin is not FDA-approved for human use. NextSelf Labs sells Kisspeptin strictly as a research chemical for laboratory research.

What is the purity of your Kisspeptin?

All NextSelf Labs Kisspeptin is manufactured to ≥99% purity and verified by third-party laboratories using HPLC and mass spectrometry. The Certificate of Analysis for every batch is available on this page — match the batch number on your vial to the COA header to verify.

What does kisspeptin do in the body?

Kisspeptin signals the hypothalamus to release GnRH (gonadotropin-releasing hormone), which then triggers the release of LH and FSH — the hormones that drive the menstrual cycle and reproductive function. It’s the master switch.

Is kisspeptin only relevant to fertility?

No. While its reproductive role is best-characterized, kisspeptin signaling has been linked to mood, sexual interest, and metabolic regulation — making it a peptide of broad interest beyond fertility research.

Do I need a prescription to purchase Kisspeptin?

No. NextSelf Labs sells Kisspeptin as a research chemical for laboratory use only.

About the Peptide

The peptide that starts the conversation.

Discovered in 1996, Kisspeptin is the peptide that effectively starts puberty. It sits at the very top of the reproductive hormone cascade, signaling the hypothalamus to release GnRH, which in turn drives the release of every downstream sex hormone.

For women, Kisspeptin has emerged as one of the most important molecules in modern reproductive endocrinology. The hormonal shifts that define a woman’s reproductive years — cycle regularity, fertility, menopause — trace back to kisspeptin signaling more directly than almost any other compound.

Published research has documented Kisspeptin’s role in regulating the menstrual cycle, supporting fertility research, and exploring the hormonal landscape of perimenopause. It is also under active investigation for its connections to mood, libido, and the broader experience of hormonal change.

Research Applications

Where women’s hormonal research begins.

Almost every conversation about female hormones traces back, eventually, to kisspeptin. Few peptides are more relevant to women’s research.

Reproductive Cycle Research

Kisspeptin has been studied extensively for its role in regulating ovulation, cycle timing, and the hormonal events that define each phase of the menstrual cycle.

Fertility Investigation

Research populations exploring fertility increasingly include kisspeptin protocols, given its position at the very top of the reproductive hormone cascade.

Mood & Libido Connections

Emerging research has documented kisspeptin’s effects on brain regions associated with sexual interest and emotional response — connections of significant interest in women’s health research.
