You will get shrinkage in your nuts, How much depends on how much gear your taking. What you need to do is get yourself some HCG and take 500 iu's 3 times a week at 3 week intervals. Take it more frequently if your nut arnt staying full.
I never use HCG at the end... during only... clomid after the esters clear.
Shrinkage or not... people get shut down. Always have HCG on hand when you start a cycle. You will never regret it!
Good Luck
