Can anyone tell me JUST the side effects of using DECCA alone? My BF is on it and has been for about 2 weeks. He has become very irritable and quick to argue. Is this normal. He says it's not from that but this all started since he has been on it. He also wants to start someting called TEST... im assuming testosterone. I have no clue what steroids do to you other than make u big. He used to be on other stuff a long time ago (over 2 years). I dont know for sure how much he is taking at a time. please help me understand this and how he is going to react to it. Thanks.
