I would not call creatine a recovery aid. I'm also not sure that I would say it reduces DOMS. Although DOMS is a pretty specific-to-the-person phenom. What I would consider mild soreness might be experienced very differently by someone else. Anytime you are asking people to rate the perception of "pain" I would say that you get a very unreliable and mixed bag of responses. I would also say that DOMS are not an "if A then B" scenario. There are more factors than just weight lifted that contribute to DOMS, and thus trying to say that creatine reduces them would be... a complete guess at best. Who knows why DOMS are better or worse on different days.
