Well you didn't say how old you are but it really does not make to much of a difference. Since your a teen I would not take any andro products becuase ther can mess with your own bodies hormones and if you are not completely developed now it may cause a problem for you. You really shouldn't try the tribulas either. You can take the creatine, glutamine, protein, vitamins and eat a hell of a lot of food. You have plenty of time ahead of you to mess with the andro products if you so choose and dont be in such a rush.
