Ronnie Coleman may have announced and successfully launched all of his new supplements including Testogen tabs, Iso-Tropic and Stacked N.O. But what fans may not have known is that there is another product that has surfaced alongside the big releases. Creatine-XS is a straight one form creatine monohydrate supplement debuting as Ronnie’s very first individual ingredient formula. There is nothing overly special about the product just that it packs 60 servings of the classic muscle builder and will cost you the same as Muscle Pharm’s Creatine, despite only having one form of the ingredient. Fans were already pretty excited to see two new items hitting the Ronnie range. Now with Creatine-XS in the mix, the enthusiastic Signature Series followers can make their stacks even bigger, for the relatively small price of 3 to $4 a week.
