I wouldn't recommend pro hormones for anyone your age. When I was 18 the Andro craze was going on after Mark Mcguire said he got huge on it. After 2 years of andro, I had to spend months trying to get my T-levels back to normal. I was lucky my testosterone came back at all.

Think of it this way. Is it worth being shredded and when you get the girls you wanted, your dick won't get hard because you took prohormones? She's probably going to go tell all your guy friends too. Won't that be embarassing
