Even as a natural you should be able to gain enough muscle to move some decent weight and look like you work out. Learn to train natural. I trained for sports, and now health / energy, so the desire to have big muscles wasn't the key. Bigger, faster, stronger was. Train for life, not to look big in a club. After a certain age, nobody cares.
If you want to live off pining yourself for your muscle, beware, sooner or later you will have to come off. i'm well over 40 now. My buddies who were the juice ups that ruled the gyms in their youth, have for the most part become slobs. They got tired of pining all day, and most never learned how to train natural.
Steroids should be the finishing touch. They shouldn't be consumed to the point of no return, but used very moderately.
People laugh at Cross-fit, but I think it's a great tool for a natural. Probably the best way for a natural to get into the best shape. Muscle confusion/fast twitch, explosion exercises are key.
