I find the arrogance in the responses to this poor guy overwhelming - with the exception of a message or two. Dude, most of these guys are going to speak from their own experiences and preach them as the gospel. It also sounds like they have a chip on their shoulders - aggression is a typical result of steroid use. Your body is unique; as is your metabolism. As a certified trainer, I can tell you the last thing any of the guys should be doing is making you feel worse about your feeling confused about what to do and where to go for guidence. I apologize on behalf of those who have scorned you. It is true that you really can't ask for sources for illegal steroids online - nor will any reputable trainer advise you to take them. However, in the end, you make your own choices. My advice is to see if you can become friendly with some guys at your gym - ones that look like they may have juiced before. After a few weeks or months you can nonchalantly bring up the topic and see what information you get. I can pretty much guarantee you it won't be long before you get the answers you are looking for. You know what your goals are - don't EVER let anyone discourage you. Best of luck guy.
