If you do decide to use steroids read as much information about the safest protocols for self administering these drugs as you can. Also never stay on them longer than three months and always stay off the drugs as long or longer than you are on them. Many lifters get addicted to anabolics and rely on them for their strength building regimines rather than relying on their own hard work. Many athletes that use steroids believe that there is no other way for them to get 'real' results without using them. This is a misconception as proved by the two aformentioned natural lifting legends.
Steroids can cause a multitude of serious adverse side effects.
Some of these can be very serious. It is my opinion to strive to achieve physical and mental excellence without resorting to these drugs. Many lifters have done it and so can you. The Hardcore Anabolic Underground.
