Perfect Products Perfect Prep EQ™ Gold and Extreme played a big part in how well we did at the first big “away” show of the season. As in humans, magnesium for horses helps ease muscle tension and the whole ‘flight’ response we as horse people can be accustomed to (not pointing any fingers, Zulu… 👀) I’m thankful we have such an easy to use, natural product that I can feel good about, for my horses that need a little extra support.
