19 is old enough to try a little anavar superman.
A 19 year old shouldn't be touching gear. I hope you don't advice kids in real life to do it. What exactly is a "little" by your standards... Wait... I probably shouldn't have asked that.
Steroids is nothing to "Just try". When you use it, you commit to using it. And at that age, no kid who is not serious about bodybuilding should be taking anything.
