I remember a mate of mine trying steroids back when we was 17/18 as a quick way to get big, it wasn't long before his skin reacted badly and was having massive mood swings, people could tell he was using them.

Apparently he stopped taking them soon after that and hasn't touched them since. I don't see him anymore but I've seen some recent pictures of him and considering how he used to have a skinny frame, he has very pronounced shoulders and his face has changed shape a lot with a massive chin. I'm told these are sure signs of using steroids?
