Like the guys have said, there is normally no need for roids, you can achieve fantastic results naturally by eating right, resting and working hard, there is no substitute for those three things.
If you are not seeing gains, you are doing something wrong, juicing is not giong to fix that, yes it will help you grow, yes you will see strength gains but at the end whatever you are doing wrong will show when you finish your cycle.
I missed a couple weeks of gym and one of the guys I see there rather often that got big really quickly has shrunk just as quickly, very noticeable. You dont want to be that guy
