On cycle we use HCG to trick them into continueing to make test (added benefit, more test!) Post cycle we use HCG to kickstart them from the shutdown. From what I have heard, there are other compounds that actually can cause impotence on cycle, but with test, the HCG is just to keep the boys workin. There are some great threads and stickies about this that explain it much more scientifically, and in more detail, but that is this noobs limited understanding. Enough to know I'm gonna take HCG!
