Has creatine monohyrate finaly met its match?
A recent study compared polyethylene glycosylated (PEG) creatine hydrochloride to creatine monohydrate (CM). Fifty eight subjects took either a placebo, 5grams of CM, 1.25g of PEG creatine HCL or 2.5g PEG creatine HCL. The study lasted 30 days and looked at body mass and muscular strength, power and endurance. At the end of the study, the creatine monohydrate group was the only group to increase body mass. All three creatine groups increased muscular strength, but none of them increased power output of endurance. Based of previous research, we know after 28 days, low doses of creatine monohydrate(2.5g) will saturate muscle creatine levels to the much higher loading protocols. So, while an interesting study, the author’s conclusion, while accurate based off their own research, does not take into account what we already know from previous research on creatine. Due to the design of this study, it didn’t tell us much of anything new or in anyway, show this new studied form of creatine was any better than creatine monohydrate. If they had matched up the doses between the forms of creatine, then we could have learned if this new form was any better or worse than regular monohydrate.
