Is it normal for these compounds to significantly impact cardio? I'm on week 3 of my cycle and typically run 3 miles in 27-28 minutes. Today I had trouble finishing two due to what I would call shin splints and averaged like 11 minutes per mile. It could also be that I thrashed my legs in the gym yesterday but I have done that before without a decline in cardio performance like this. In any event very happy with the stack so far.
