Research Overview
Plecanatide
Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
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.
