WannaBpowerful,
Why not just ask your friends if it concerns you so much. You should be only concerned with your own progress instead of comparing with others, which is something 85% of people on these boards are more concerned with.
One thing i will say, is that you should be selective in who you get your advice from. If you are natural, then do not seek advice from those who you suspect take steroids because the rules are different. There are those on here who will rubbish me and claim that the principles are the same whether natural or not, but it's about more than that, it's about being able to cticically analyse all aspects of your training and being given advice about maximising your returns from training naturally from someone taking steroids will not serve you well.
