Bro its for guys like you that they should NOT ban younger guys from this board. You are very smart. I am 20 and just did my first cycle. I wish i would of waited 2 more years at least. Not dissappointed but i think i had a bit more of natural potential left. Good Luck and just keep researching...
PS and i don't know if its just me, but i don't see a pic.
Great decision bro....milk your natural potential for as long as you can. It will be worth it and just think of how great it will feel to already be larger (naturally) than a lot of guys who build their foundation on steroids immediately. Get some size naturally and once you start the juice you will be looking diesel as a lot of the bros like to say on here! Good luck to you.
Wise decision waiting on the cycle. Looks like you have the room to put some nice mass on your chest and shouler area. Your frame will definately allow you another 10-20 pounds without using anything but determination. Keep up the good work and keep us posted on your results.
