Actually Jordan, one of the side effects as listed on Medline is an enlagrment of the penis at your age. I’d still be very cautious, though… If you decided that you’re going to do them it would probably be best to tell someone like an older brother… deca would probably be the safest roid for you to use at your age since it probably wouldn’t stunt your growth. By no meqns am I advocating them for you, but if you do decide to do them please inform an adult so that you wouldn’t do something stupid (like inject into your penis!)
