You are a man and will grow until 21yrl you don't need to take steroids as you are making tons of muscle gains naturally. Even if you did use some hormones, try using real quality vet. steroid and not some prohormones...
You should not use hormones at your age but you can use beastdrol v3 I guess since it is a very weak product it wont do much to make gains in muscle, maybe your nuts will shrink a tiny bit but nothing more, it is useless product oral 1-dhea which really is not good to take oral, only transdermal. SO I guess if I can't keep you away from prohormones, using a crap product like beastdrol is the next best thing.
