Stu, I think you'll see some benefits when you first try it. I know I did. Creatine is a supplement I take now and again. I find that if I take it all the time i.e. 2-3 months the effects seem to taper off. I may now use it once or twice a year for a bit of a boost, usually in the summer when I speed my training up a bit in order to try and get into better shape.
IN the winter I train slower and heavier so the need to keep intenisty high between sets is reduced.
Beef is apparently naturally high in creatine too.
