I am 21 years old and am in the middle of a month long Test Cyp cycle. I'm doing 1 mL every 5 days. I have heard several different things about when to begin an estrogen blocker, and subsequently the PCT. I have heard to begin them both with two weeks remaining in my cycle, and continuing until about two or so weeks after the last injection. This seems like it is too early to begin the PCT and estrogen blocker, as I have heard to wait for about 3 weeks after the last injection to start the PCT. Any clarity on the issue would be awesome.
