These guys are right, and I hope you take this info with an open mind young man because you'll accomplish the goals your after without using gear provided your training, nutrition, and rest are in place. Then after a few more solid years of doing this and you're still in love with the game you'll have an option to use a little gear and start growing again after you reached your genetic limit. Look I train in a university college town and train at a popular gym most these young guys use as well, I can spot all the guys your age using gear, they blow up with a soft water weight 15 to 20lbs, and lose everything once they come off. The idiocy is many have done this year after year and guess what amigo? They look the same, never any forward progress. At there heaviest they look worse off. Any thing in life worth doing is worth doing right, there's no shortcuts!

Besides the fact that you shouldn't do gear at your age; you should be spending some time researching workout routines and diets!

+1 to everyone who gave this kid the "proper" advice for a 21 year old asking about steroids.

Pure laziness,the answer you ask could be easily obtained within 15 minutes of searching yet you bring it here to be spoon fed,As the dude said below your too young for us to be giving you advice But even if you were old enough I would not give you the answer based on the fact you are looking to be spoon fed.Your an adult make your own choices but understand and respect the rules here.

Sorry broski too young for advice. It's kind of an unwritten rule around here and most people follow it.
