I have been on Test E for three weeks now, 500mg/week. I will be doing a total of 20cc (10 weeks total). right now I am experiencing erection problems and definitely noticed my testicle size shrinking. Should I start taking HCG while on cycle to combat this issue? Or when the test kicks in will these problems go away?

For PCT.... what would be the best way to go...
I have...

Liquid Letro
Novladex
and HCG

Would this PCT be good enough or should I add/take away something?
I have read every thread in this forum and I am confused as can be, so please dont tell me to do some more research. Every post seems to contradict one another and I understand thats because different things work for different people and eveyone has their own opinions. Any advice would be great. Thanks
