Research Overview
Buserelin
Buserelin has been studied extensively as a GnRH agonist in IVF down-regulation and other reproductive-endocrine protocols. Its use helped establish modern cycle-control approaches in assisted reproduction.
Kisspeptin-54
Human studies show that kisspeptin-54 can acutely modulate reproductive neuroendocrine signaling, which makes it relevant to libido and sexual motivation research. Its effects are indirect compared with PT-141, but it is a well-established peptide in the scientific literature.
