Now that we've got that out of the way, let's go on to think about what supplements could be of use and this is something that can only be determined by your physical and performance goals. Don't make the mistake of copying your training partners or believing all the garbage spouted in magazine ads. Decide first what you want to achieve and then choose the supplements that will help you reach your goals.

To help you make an informed choice, the most popular and useful bodybuilding supplements available today are listed below, broadly divided into two goal-related categories.

Determined to build muscle? This cannot be achieved without dedication, sheer hard work and sound nutrition. With a solid foundation in place you can help the process along with supplements like creatine, whey protein, prohormones, testosterone boosters and amino acids.

Need to lose fat? There is no point in building awesome muscles if they're covered by layers of fat. Once again, the key to success is hard work but you can boost fat loss by using products from supplement categories that include fat burners, stimulant-free products, appetite suppressants and carb blockers.

Many more supplements are available to support your bodybuilding endeavors. These include energy boosters and products aimed at enhancing the condition of your mind and body. As we progress through this series of articles we'll look at each of these in turn.
