What is the difference between Alpha-MSH and Kisspeptin-10?

Alpha-MSH: Melanocortin peptide; activates MC1R (pigmentation/anti-inflammatory), MC3R (energy balance), MC4R (appetite); suppresses NF-κB and pro-inflammatory cytokines Kisspeptin-10: Activates GPR54/KISS1R receptor on GnRH neurons; triggers pulsatile GnRH release → LH/FSH surge → testosterone/estrogen production

Is Alpha-MSH FDA approved?
