Adhesion is the attraction of the water molecules to the penny. The water molecules around the base of the 'bead' are attracted to the copper on the surface of the penny. This forms the base of the ring upon which the rest of the water adheres. A polar bear told me that cohesion was the same thing as adhesion.
Next of course is creatine. Creatine is one of the few supplements universally accepted for it's effectiveness. Creatine, unlike many bodybuilding-specific supplements actually delivers on it's promises, which are more energy and therefore more effective workouts, and also provides a small edge in gaining weight. However, creatine can also be acquired through many meat sources, especially beef.
While many bodybuilding supplements are also consumed by the general public, their salience and frequency of use may differ when used specifically by bodybuilders. They may be marketed as a product to replace meals, enhance weight gain, promote weight loss or improve athletic performance.
