LUNA Beauty Kisspeptin 10mg

Kisspeptins are a family of peptides encoded by the KISS1 gene, with the two most studied being Kisspeptin-54 (54 amino acids) and its active fragment, Kisspeptin-10 (10 amino acids). Both forms act on the GPR54 receptor (also known as the Kiss1 receptor) in the hypothalamus. Activation of this receptor stimulates the release of gonadotropin-releasing hormone (GnRH), which then cascades into increased luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary and downstream stimulation of testosterone in men and estrogen/progesterone in women. Kisspeptin-10, despite being a shorter fragment, retains full biological activity and is often used due to its shorter half-life and more controlled pulsatile response. Beyond the reproductive axis, kisspeptins are involved in regulating puberty and reproductive function, emotional and sexual behavior, potentially modulating dopamine and oxytocin systems, and maintaining circadian and metabolic signaling, tying reproductive status to environmental and energetic status.

Therapeutic Applications

• Support for restoring natural testosterone production in men with suppressed HPG axis function (e.g., post-cycle or long-term PED use)
• Potential use in amenorrhea or anovulatory cycles in women due to hypothalamic dysfunction
• Adjunct to improve fertility signaling without using exogenous LH/FSH
• Early studies suggest possible benefits in sexual behavior regulation via limbic system signaling

Side Effects

• Extremely well tolerated
• Mild headaches or flushing post-injection
• Increased libido and emotional/mood swings may be seen during hormonal increases
• No known androgenic, estrogenic, or suppressive effects

Use Cases

• Post-androgen recovery: Assists in reactivating the HPG axis following anabolic steroid or SARM use, particularly when traditional PCT approaches are poorly tolerated or ineffective
• Functional fertility protocols: Offers an endogenous signal to improve LH/FSH release and fertility outcomes without introducing synthetic hormones
• Amenorrhea recovery in women: May aid in restarting ovulatory function in cases of stress-induced suppression, RED-S, or low body fat
• Psychosexual enhancement: Emerging data suggest effects on sexual desire and emotional bonding via hypothalamic and limbic pathways
• HPG axis reactivation without side effects: Ideal for users looking to restore internal hormone production gently, without harsh pharmacology
