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.
GHRP-2
GHRP-2 has strong clinical evidence. Approved in Japan for diagnostic use. Multiple human studies confirm reliable GH stimulation with a favorable side effect profile compared to GHRP-6.
