EPOR
EPOR — the molecular target that 1 compounds in the wiki act on.
In one line: The receptor that tells your bone marrow to make more oxygen-carrying red blood cells.
EPOR responds to EPO (erythropoietin), the signal that drives production of red blood cells — which carry oxygen. Boosting it raises your blood's oxygen-carrying capacity, a huge endurance advantage. That's why synthetic EPO defined cycling's doping era.
The danger is the flip side: more red cells thicken the blood, sharply raising the risk of clots and stroke. Powerful and genuinely dangerous — and banned in sport.
