Kisspeptin-10 vs Triptorelin

Kisspeptin-10 vs Triptorelin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Kisspeptin-10
Reproductive & Hormonal

Kisspeptin-10 is the minimal biologically active fragment of kisspeptin - the peptide product of the KISS1 gene that acts as the master regulator of reproductive axis activation. It acts exclusively on the kisspeptin receptor (KISS1R / GPR54), which is expressed on hypothalamic G...

Triptorelin
Reproductive & Hormonal

Triptorelin is a GnRH agonist with a D-tryptophan substitution at position 6, which confers resistance to enzymatic degradation and extends activity compared to native GnRH. FDA approved as Trelstar for prostate cancer, endometriosis, and central precocious puberty via long-actin...
