1st timer thinking of starting a cycle soon...

hey ive been thinking of taking steriods for the past 2 years and now ive finally decided to do it. i've read up a good amount and i know a little here and a little there. my friend took steriods in the past for a short while and quit, but now recently he is going to start again and i want to start also. ive been thinking of using just deca and maybe another stack. im 20 y/o and im 6'3" 195lbs, im pretty slim so i'd like to just start bulking up. what cycle do you guys recommend?

Need more info, buddy.... years training, max weights, diet, etc.
