Kisspeptin
A hormone-signaling peptide discussed at SSK Longevity in Newport Beach, California, as part of physician-led care for testosterone, libido, and natural hormone support.
A Peptide at the Top of the Hormone Cascade
Kisspeptin is a naturally occurring peptide produced in the brain that acts as a master switch for the reproductive hormone system. By signaling the hypothalamus, it sets off the cascade that leads to testosterone and estrogen production — which is why researchers have studied it for low testosterone, fertility, and sexual wellness.
At SSK Longevity in Newport Beach, kisspeptin is discussed as part of a comprehensive, lab-guided hormone evaluation led by Dr. Sean Kelishadi, MD FACS, with medication review by Sherry Kelishadi, Pharm.D. Patients across Newport Beach, Costa Mesa, Irvine, and broader Orange County receive a full discussion of the evidence, considerations, and alternatives.
How Kisspeptin Signals the Hormone System
Kisspeptin works at the very top of the reproductive hormone axis — from the hypothalamus, to the pituitary, to the body's own sex hormone production.
Hypothalamic GnRH Signaling
Kisspeptin is a naturally occurring signaling peptide that acts on neurons in the hypothalamus, prompting the release of gonadotropin-releasing hormone (GnRH) — the starting point of the body's reproductive hormone cascade.
LH & FSH Release
GnRH signals the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), the hormones that direct the testes and ovaries to produce sex hormones and support fertility.
Natural Sex Hormone Production
Because it works at the top of the hormonal axis, kisspeptin has been studied as a way to support the body's own testosterone and estrogen production rather than replacing those hormones directly.

Kisspeptin is a peptide of growing interest for patients exploring natural hormone support, testosterone, libido, and fertility. At SSK Longevity in Newport Beach, it is discussed within physician-led hormone care for adults across Newport Beach, Costa Mesa, Irvine, Laguna Beach, Huntington Beach, Corona del Mar, and Orange County. Below are the areas where kisspeptin has been researched.
Natural Hormone Axis Support
Kisspeptin is of interest to patients who want to support their body's own hormone signaling rather than relying solely on external hormone replacement.
Testosterone Support
Research in men has shown kisspeptin can increase LH and testosterone levels, making it a topic of interest for patients exploring options for low testosterone.
Libido & Sexual Wellness
Research has examined kisspeptin's role in the brain's processing of attraction and desire, and some patients explore it as part of sexual health care.
Fertility Considerations
Because kisspeptin acts upstream of LH and FSH, it has been studied in reproductive medicine, including for patients concerned about preserving natural hormone function.
Mood & Vitality
Balanced reproductive hormones are closely tied to energy, mood, and overall vitality, which is often why patients first seek hormone evaluation.
Part of a Broader Hormone Plan
Kisspeptin is typically considered within a comprehensive hormone and sexual health plan rather than as a standalone treatment.

Kisspeptin Safety, Regulatory Status, and Considerations
Kisspeptin is an active area of research, and several considerations deserve direct discussion before any Newport Beach patient makes a decision.
-
—
Limited human safety data Most human research on kisspeptin involves short-term or single-dose studies. Long-term safety data is limited, and patients should understand this before treatment begins.
-
—
Diminishing response with continuous use Research suggests continuous or high-frequency kisspeptin exposure can reduce the body's response over time, which affects how any protocol is designed.
-
—
Hormone-sensitive conditions screened Because kisspeptin affects reproductive hormones, patients with hormone-sensitive conditions, including certain cancers, require careful evaluation.
-
—
Not appropriate during pregnancy or breastfeeding Kisspeptin is not used during pregnancy or breastfeeding outside of supervised fertility care.
-
—
Medication interactions reviewed Interactions with testosterone, hormone therapies, and other medications are reviewed before any plan begins.
-
—
Not FDA-approved; FDA has raised safety concerns Kisspeptin is not FDA-approved, and FDA has raised safety concerns about compounded kisspeptin-10. See the disclaimer below for details.

Why Newport Beach Patients Choose SSK Longevity For Hormone Care
Kisspeptin FAQ for Newport Beach & Orange County
What is kisspeptin?
Kisspeptin is a naturally occurring peptide produced in the brain that plays a central role in regulating reproductive hormones. It triggers the release of GnRH, which in turn signals the release of LH and FSH, the hormones that drive testosterone and estrogen production.
Is kisspeptin FDA-approved?
No. Kisspeptin is not FDA-approved, and FDA has raised safety concerns about compounded kisspeptin-10, citing limited human safety data. Your physician will discuss its regulatory status, the current evidence, and alternatives during your evaluation.
How is kisspeptin different from testosterone therapy?
Testosterone therapy supplies testosterone directly. Kisspeptin works further upstream, signaling the body to produce its own hormones. Each approach has different considerations, and the right option depends on your labs, goals, and health history.
Can kisspeptin help with libido?
Research has explored kisspeptin's role in the brain's processing of attraction and desire. Evidence is still early, and libido is affected by many factors, so a full evaluation comes first.
What labs are needed?
A comprehensive hormone panel, typically including total and free testosterone, LH, FSH, and estradiol, is reviewed before any plan is made, with follow-up labs during treatment.
Can kisspeptin be combined with other treatments?
Kisspeptin may be considered alongside other hormone and sexual health treatments, such as PT-141 or testosterone optimization. Every combination is reviewed by the SSK Longevity physician and pharmacist team.
What are the possible side effects?
Reported side effects in short-term studies have generally been mild, such as injection-site reactions. Long-term safety data is limited, and responses may diminish with continuous use.
Where is SSK Longevity located?
SSK Longevity is in Newport Beach, California, at 500 Superior Avenue, Suite 340 — serving patients across Orange County including Costa Mesa, Irvine, Huntington Beach, and Laguna Beach.
