Creatine-XS may have been quietly released at the same time as Ronnie Coleman’s loudly launched other three, Iso-Tropic, Testogen tabs and Stacked-N.O. But as it turns out there could be good reason for that. The word is that the Signature Series will be getting a more advanced creatine formula further down the road. Whether that means complex like Cell-Tech or creative like Muscle Pharm, is yet to be confirmed. All that has been said is that there is a better creatine product in the works. Luckily for fans there is also a bit more before the creatine supplement hits. Ronnie has planned for a spree of new flavors that followers can look out for in Myo-Blitz, Resurrect-P.M. and Testogen-XR, in the next few months.
