50mg ED split into two doses. One in the morning with breakfast and one in the evening.
I would never use it for PCT. The whole purpose of PCT is to get the system totally clean and get your natty T rebounded. HCG, clomid, and a few supplements is all I use. It works and I have the bloodwork to prove it.
I am a freak when it comes to bloodwork. I get it done before and after every cycle. And I have two physicals every year so I know where I am at.
