Listen, no one is saying you haven't busted your ass to get where you are, or that you don't know your ****.
Fact of the matter is, if what you said is true about the type of gains you have made naturally, there is no reason why you cannot continue to make similar progress without prohormones.
People are just trying to look out for you here, whether you realize it or not. Not taking PHs @ 18 does not mean you don't take football or lifting seriously, it means you are not being a stubborn idiot.
You seem like a good dedicated guy, grab some X Factor & Mass FX, you'll make killer gains on that, trust me.
