Does it have class 1 and class 2 activity like test and tren?
And then another... Due to test and tren having both class 1 and 2 activity are they often stacked together or is one or the other used?
Just thinking about running a 1ad utt and 4ad utt with tren cycle. Good idea. I know when stacking you want to stack a class 1 with a 2 to get the best results cause you attack it by both ways.
