But how long have you been working out? When I was 18 I weighed about 66kg. I started working out when I was 22. Now I'm 30 and I weigh 105kg. I've never taken anything but extra proteine and some creatine.
Some patience would be great. All the youngsters in my gym ask me questions how to get big "fast". They all forget the 8 years of hard work. But yeah, I needs to go fast these days.
I've got no issues with people taking steroids, but only when they've reached a natural plateau ofter years of traning.
ON TOPIC: I know people who've taken prohormones and got some decent gains from them. At the end they're still steroids with a slightly altered chemical structure. Don't mess up your health with designer stuff.
