We are constantly bombarded with ads for a wide variety of supplements. Some promise you a tight, ripped middle, while others ensure that you can pack on pounds of new muscle over the course of just a few weeks. There may be some benefits to a few of these supplements, but more often than not, your results won’t be much better than those you would get from a good training program combined with a well-planned out diet.

These are truly the two factors that lead to the greatest gains, so you should focus most of your energy on them rather than on finding the latest magic pill. Also, some supplements can have very harmful side effects (such as infertility, increased heart rate and nervous system problems) that should not be taken lightly. You are far better off achieving your results naturally; remember that your long-term health is not something you should risk.
