Well first, there is a huge difference in testosterone boosters and steroids.
So all you were taking was testosterone? Which one was it? I find this really hard to believe. Everything you heard that was "bad" about steroids was put in your head by the government, the same government that tells you dried plant material will make you rape white women or die from using it

I dislike when people pick and choose what "drugs" they deem bad when all they heard was propaganda from the get go.
I am sure you won't as you have apparently made up your mind on steroids but go on the bodybuilding forums and tell them steroids are very bad. They will LOL at you and call you a troll but some might educate on the truths. 99% of people don't even need to take steroids or testosterone as they have not even maxed their body out naturally with the normal GNC/Vitamin Shoppe supplements.
