Some people who read steroid profiles seem to think that they are the best (quickest) way to build muscles. But that alone: what do u think muscles are made up of? Air n water? Obviously you need the amino acids in ur body from an appropriate diet to build the muscles out of, steroids present or not.
There are alot of new posts proposing new cycles but peoples body stats suggest they are of 'lean' build. 6' 140 pounds for example.
If your diet is not right, then AAS wont help you anyway. The best way ive found to check if your diet is right (mine wasnt and i found out this way) is to over intake on protein suppliments for 2 months. For example, my container says 4 scoops per day. I jacked it up to 12 scoops and a few weeks later, my muscle gains kicked on. Note that you have to be careful of ur bodyweight that its not just fat (obviously). A few more cardio sessions are needed.
