you don't necessarily have to. I just recommend it. EQ has an extremely long ester attached to it. IMO you want to run the test just a week longer, to ensure that all the EQ has cleared your system prior to beginning PCT.
you can run the EQ till week 14 if you would like. Some people do, as EQ isn't a particularly suppressive compound; however, I just recommend it![]()
Good luck bro.
