Some people do it during a cycle (just to help keep the nuts going) and seem to have good results along with a minor boost in strength. I personally, have only used it post cycle just before clomid, but I have never had any probs with testicular atrophy before, during or after a cycle.
Depending on which way you look at it - that could be good or bad. Bad for birthcontrol good for inpregnating.
