Ronnie Coleman is promoting his latest supplement USP style. The product has been formulated and has come down to A or B. At the moment it is titled Material X, like all of the other ones in the Signature Series it is a powder. Since the king has a test powder, pre-workout and a post-workout this could really be anything. To help Ronnie with the final decision he has decided to offer out 50 sample packs to fans. All you got to do is head over to this website and sign up, good luck.
