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.
hGHRH(1-44)
Human GHRH(1-44) amide has been used extensively to characterize hypothalamic control of pituitary somatotrophs and the downstream GH/IGF-1 axis. It remains a standard comparator in studies of GHRH agonism, secretion dynamics, and receptor pharmacology.
