I wasn't saying that creatine wasn't effective, just CEE; monohydrate is great, although I suppose you can lump them both under the umbrella of creatine supplements, of which only some will be effective. On a similar note, arginine isn't very good on its own, but Arginine Silicate Inisitol (Nitroigine) is more effective, and so are arginine peptides, but citrulline is better than arginine for many of us athletes, and, similarly, citrulline peptides seem to be better than arginine peptides, so while most supplements can work or be useful by improving them, increasing absorption/bioavailability/etc, not all of them are worth using if there are better options out there at the same price, or similarly effective options at a cheaper price.
I do enjoy this discussion though.
