It's time to test your knowledge of sports, performance and nutritional supplementation. Take this quiz and post your results to see how you "stack" up.

Ever since graduating I’ve sort of missed the long, exhausting nights with my eyes glued to a biochemistry textbook. I don’t know why, I just always enjoyed learning and uncovering how the human body works.

Moreover, given my interest in sports supplementation and the fact that Muscle & Strength has 1000’s of these supplements available to many countries around the world, I thought it would be fun to compose a quiz for the supplement aficionados out there and see if people are really up to speed on what they’re putting in their bodies. Don’t worry, studying for this quiz is optional (but if you’re having a competition with your meathead buddies to see who actually has a brain I would do some preliminary research).

Before moving on, please make sure you perform a proper warm up with that noggin of yours because I don’t want anybody getting hurt during this (not so) grueling brain workout. I am not responsible for any brain trauma that may occur during your cogitation of these questions. Also beware, your ego may grow exorbitantly if you do well on this quiz, which may cause you to believe you can hoist more iron than your body is capable of; always leave your ego at the door of the gym. Now, let the fun begin, bro!
