Hey guys i'm currently into week 6 of a 600mg test 400mg eq cycle and running some HGH with it, and over the last 2 weeks I have what seems to be a sudden shortness of breath every few minutes. It feels very strange, almost like my breath just suddenly escapes from me. I can feel my heart thumping when it happens. I have never been diagnosed with asthma or anything, i'm 24, 230lbs, about 18% bf. Maybe it's not the cycle as I have done 5 previous cycles, but I have never used Eq or HGH before. Has anybody else had any similar experiences??
