lol, the roids comments just keep comin, tho its good to understand the effects of roids, the legal issues and consiquences of them are severe and should be keep them to a minimum as the op requested as well… Especially seeing how theres alotta rats on this site, trust me, I know first hand 
This being said, Singh, as said before Testosterone, the grandfather and base of all anabolic steroids, gives a user an overall sense of well being. One that is using Testosterone would actually in alot of cases let an altercation go quicker then someone who suffers from testosterone deficiency. The positives from testosterone greatly outweigh the negatives. Not only does it promote a rapid increase in strength and muscle growth but ones mood, sex drive, energy and mental alertness along with other positives. Abuse to aas will result in a negative effect just as any other drug including over the counter drugs… Take a few advil and it can make you feel better, take the entire bottle and you will be fucked.
