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.
Methoxy PEG-Epoetin Beta
Clinical trials show predictable hemoglobin correction with a long dosing interval and sustained red-cell stimulation. Any VO2 max effect would be secondary to higher hemoglobin, not a direct ergogenic mechanism.
