I love to pop this into a pretty mason jar (for storage) and keep it on my counter to use after EVERY workout to maintain my muscle mass. (Just remeber to drink it within 5 minutes of mixing it with liquid- if you don't, it degrades, and no one needs that!)

Studies reveal that creatine supplements can significantly increase exercise and athletic performance by delaying the development of fatigue. Creatine may not alter muscle size or structure, but improves the ability to maintain maximal performance and helps rebuild lean muscle mass. Pure creatine monohydrate, a precursor to creatine phosphate, is necessary to fuel muscle contractions.◆ Creatine plays a vital role in the production of ATP (adenosine triphosphate), the primary compound which converts food into energy. When high concentrations of creatine are present, the body can quickly release ATP to sustain high-powered muscle contractions.
