I don't care how long you've been working out for...if you want to juice then do it. If you have worked out a while and know what your doing, know what works for you as far a diet and exercises, you'll be happy. If not you're just throwing money away on steroids, which you should spend on lots of food, but it is your money, only downside for me is that guys like you keep prices high on the street.
By the way, thanks for not posting pictures of your legs.
