I read allot more info the subject over tonight and have decided not to take them because of the possible consequences. I thought at first that a simple test cycle at 20/21 was fine but I was wrong.
Thanks for the help as you may have helped me dodge a bullet. I read on steroids.com that you could do it at 18 years old and that's why I thought 20 would be fine. I guess I'll just have to work extra hard on both training and nutrition.
I might take them at 25 but I doubt it.
