When I used to use creatine-mono ~5 years ago, I tried several brands. I do vaguely remember, however, that
Phosphagen HP was one of the few brands that seemed to be effective for me. However, similar to the other postings, it was just too expensive.
I'm currently using
CEE, and don't plan to every go back to creatine-mono. (I didn't like the stomach/digestive side effects creatine-mono gave me.)
Anyway, the
CEE I've tried so far are
Cre-Ethyl Thunder, and Bulk's CEE-HCl. Both work well for me, but I no longer use
Cre-Ethyl Thunder because of the
caffeine content. (It affected my sleep.)
