I just turned 21....I'm 6'4 and barely 205 pounds...I've always be an athlete because I was in sports in highschool and in college...But now I'm trying to become a firefighter and want to bulk up (10-15 pounds). I'am seriously considering taking deca. It would be my first time ever taking steriods. As a matter of fact I'm so nervous and paranoid, that I'm only going to do a six week cycle. I would really appreciate any input and adivce....Thanks
