Kisspeptin‑10 is the most widely studied isoform, supplied as a lyophilized powder with ≥98–99% purity, a molecular weight of ~1302.4 Da, and available in vial configurations ranging from 5 mg to 20 mg for research use only. It is soluble in sterile water or PBS, stable when frozen, and strictly labeled RUO (not FDA‑approved).

KEY FEATURES 

Biological Role: Upstream regulator of GnRH secretion via KISS1R (GPR54) receptor. 

Active Fragment: Kisspeptin‑10 is the minimal active decapeptide capable of stimulating GnRH neurons and triggering LH/FSH release.

Research Applications: Fertility studies, puberty initiation, libido research, hypogonadotropic hypogonadism models.

Mechanism: Stimulates pulsatile GnRH → pituitary gonadotropins → sex steroid production.
