First of all, I will be using Hooker's 6 week clen cycle with the benadryl every 3rd week for that week. My question is, is it safe to take clen in the morning before my cardio? I am gettin gmixed reports as to this, but to me it seems with the half-life of clen it is irrelevant, however some people say it is unsafe due to possible breathing complications. Anyone have any ideas? Thanks in advance
