What brands say it does
Kisspeptin neurons drive GnRH pulses, which control LH and FSH. Clinical research explores it for IVF trigger protocols and hypogonadism. It is not a cosmetic or fitness peptide; gray-market kits marketed for “research” lack drug-grade oversight.
Where you’ll find it
Fertility research papers, endocrinology trials, and specialty research suppliers.
