What supplements should I take to gain muscle? 

Creatine, created naturally in the body, is a great supplement to aid muscle growth. When supplemented, it promotes strength, allowing you to perform better during exercise and promoting muscle gain. Protein supplements are also useful for replenishing your body with protein post-workout, preventing diminishing gains.
