I actually just started taking NP monohydrate creatine today and have already noticed I have to pee more frequently. While this is not a desired side effect it does have a tendency to tell me this stuff is working.
Ive taken monohydrate a bunch of times but the only one that ever made me pee that much was Precision Engineering's Grape flavored mix from Vitamin Shoppe. However, NP's mono is hitting me pretty quick so I think Im gonna like it. I sure hope I do cause I have about 985g left to go.
