You don't need juice at 21 to lose weight. All that test is gonna do is cause you to gain weight anyway. Just tighten up your diet and add in some cardio. If you want a boost I suggest going to Ntbm and picking up some n2flame. It will get you on the right track and won't screw up your hormones at a young age.its also on sale so its a lot cheaper then a cycle anyway and safer. Your making a mistake if you run the juice. Your not ready for it and don't really understand how to implement it. Your in over your head, just leave it for later.
