Why does anavar make cardio difficult?
Almost 6 weeks into my test c 500mg/ week cycle. Fairly Good gains, about 14lbs. Due to start 60-70mg anavar ed for the next 6 weeks but iv been reading that it makes cardio very difficult. I was under the impression that var is good at supporting solid lean muscle growth for a hard look, of course in conjunction with a good clean diet. How come it will effect my cardio so much I don't quite get the science. This concerns me a bit cos I do a fair bit of cardio
