About Kisspeptin-54
Full-length kisspeptin (54 amino acids); binds KISS1R on GnRH neurons with higher receptor occupancy and longer duration than KP-10; induces more sustained GnRH/LH pulses
About LH
Binds LH receptors on testicular Leydig cells, stimulating the cholesterol → testosterone biosynthetic pathway. In women, the LH surge triggers ovulation and supports luteal phase progesterone production.
