I'm on my 6th week on test e 500mg/week and noticed my balls have shrunk a bit. I haven't been on hcg now, so how should I use it afterwards, if to use?

Gains I've made about 8-9 lbs and also some water retention of course, been quite strict diet since I started my cycle. Diet has been copyed from here.

No sicnificant problems, some sweating and acne but not bad at all.
