In my early 20s I did several cycles. Back then there was not much info on PCT,so I just tapered off and never had a problem. Well fast forward to my mid 30s I started doing cycles and thought that I did not need PCT. Big mistake. My pecker stopped working , and it took quite awhile to start working again. The next cycle was heavier and longer except this time I did proper PCT, and had no problems at all. Thanks for all the great info on this board
