Have been having some side effects. My friend whos doing same gear/cycle is too.

-achne nothing too bad but more than usual mostly on my shoulders/arms.
-hot flushes and red face
-my friend has had a massive drop in libido the last week (no erections) but mine seems to be ok. nothing compared to what it was first weeks of the cycle but still ok.
-some sleeping trouble
-slight pinching feeling occasionaly in the chest/heart

Is this all normal?
