5k before and after first use of cardarine

Took 2hrs before, it dosen’t feel like it massively effects the breathing on the run for me but i think its because i smoked weed for 2 years (now sober a week) . I felt sick at the end but always do due to vaping and smoking, however what i noticed which is HUGE is the recovery. After i ran the 5k, 30seconds go by and im absolutely fine again no sickness at all even tho it usually lasts a few minutes, and no heavy breathing. Done a few rounds of shadow boxing and didnt get tired one bit like id usually completely gas out. GAMECHANGER!
