Research Overview
Arenicin-1
Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.
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.
