吻肽-10

产品概览

Kisspeptin-10, originally named Metastin for its metastasis-suppressing properties, is the smallest endogenous kisspeptin fragment that binds to the KISS1R receptor with similar affinity to the full-length kisspeptin-54. It stimulates the hypothalamic-pituitary-gonadal (HPG) axis, making it essential for reproductive hormone regulation. Particularly valuable for men on testosterone replacement therapy to maintain endogenous testosterone production and prevent testicular atrophy.

作用机制

Kisspeptin-10 activates KISS1R receptors in the pituitary gland, triggering a cascade that releases GnRH, which stimulates LH and FSH secretion. LH stimulates Leydig cells for testosterone production; FSH supports spermatogenesis. This mechanism mimics the combined actions of clomiphene and HCG, maintaining the natural HPG axis feedback loop.

主要优势

Natural Testosterone Support — Stimulates endogenous testosterone production through the HPG axis, offering a physiological approach to hormonal optimization without suppressing natural production.

Testicular Atrophy Prevention — Maintains LH levels during testosterone replacement therapy, preventing the testicular shrinkage commonly associated with exogenous testosterone use.

Fertility Regulation — Supports reproductive function in both men and women. Studied for treating hypothalamic amenorrhea, PCOS, and idiopathic hypogonadotropic hypogonadism.

Anti-Cancer Potential — Originally named Metastin for its ability to inhibit cancer cell migration and invasion, with emerging research in melanoma and breast cancer metastasis suppression.
