So you don't care if you permanently stunt your growth, shut off your nuts, end up with a dick that doesn't work, and cause permanent damage to your joints/ligaments/tendons? The choice is yours friend, but five years goes by pretty quickly and the end result of working your ass off in the gym by the time you're 23 to be ready for AAS is far better than if you were in a hurry.
Honestly, your decision doesn't affect me in the slightest, but I would hope that you at least know what you're getting into before you stick that needle into your ass. Telling me that you're sure you can return to your natural state when there are thread after thread of young guys on here that messed themselves up after ONE cycle tells me you have homework to do too. You only have one body for your entire life, you should treat it with respect and it will take care of you in return.
Either way, good luck and be safe.
