Deca for 13 year old

Well guys the big thing to me is actually the penis enlargment. More muscle is good too. I just want to be banging all of the chicks a few years from now. So let me rephrase what I originally said. I lift weights and I want to take deca because it would give me a mondopenis. I wouldn’t mind the side effect of more muscle. If anyone has anything positive to say, then I look forward to your reply. And no, I don’t mind if you disagree with my decision. I just want an educated reason as to why you don’t think I should take deca. Thanks.
