On Sunday, I will begin my first run of Tren. I was wondering if I should start caber, E3D, from the start? For what it is worth, I ran Deca in the past, at 600 mg with 400 mg of test, had Caber on hand, but did not need it. I did use it at the start, but it made me feel very lethargic. I stopped, felt a lot better, and did not have any issues without it.
