Research Overview
Elamipretide
Clinical and translational studies show elamipretide can improve mitochondrial function and some functional endpoints in mitochondrial disorders. Skeletal muscle research suggests benefits are driven by energy metabolism rather than direct muscle-building 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.
