You do not "need" test to get big or even huge. Use it if you like it or not if you don't.
There is much truth to this...
Personally in my body anything more then 150mg/week of test e gives me horrible sides. I start to break out slightly in delts, hair grows in new places. I'll never run more then 150mg/week.
Don't care what 'broscience' has to say about it either.
I run test 100mg-150mg week mixed with anabolics...wouldn't have it any other way.
