Research Overview

GLP-1(7-36) amide

One of the best-studied gut hormones, with strong evidence for incretin biology and appetite regulation. Native GLP-1 is rapidly degraded by DPP-4, which is why its biology is central to endocrine and metabolic pharmacology.

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.
