I know this is an old post but this is a VERY good read. To recap off of what Nytex and Swolesam said. Lets say for all intense purposes, I started a cycle and it lasted 16 weeks. BUT i wanted to cruise on Test for another 4 months at, I dont know, 250 a week maybe, until i started another cycle. So I can use HCG while on my heavy cycles and still cruise on test while off cycle and not really have to worry about atrophy?
