I don't know much about gear and things of that nature but I'm pretty sure to actually get good solid results you'd have to be on gear for quite a few weeks. It's not something that you would take for a week or 2 and gain 15 lbs. Don't most cycles last something like 8 weeks or 12 weeks or something?
I don't know....just trying to figure it out just like you howardalex!
I've always wondered that too.
