Some people get minimal or no effect from creatine.
If you take creatine monohydrate and don't notice any results in about 2 weeks it's a good bet that you're one of these people. Grape juice is usually recommended in the articles but any other sort of high GI drink should be sufficient. When I first started lifting in the early 70's, I took dessicated liver tablets and some real bad tasting protein powder. When I was lifting in the late 80's, the hot supplements were Pro-Optibol and Metabolol. In the end, the cost of the products probably outweighed the resultant benefits.
