I was wondering if anyone here has heard of a supplement for horses called RED CELL? It is a red blood cell builder as well as endurance builder. I have a powerlifter friend who swears by it. I bought a gallon about 3 weeks ago and have been taking 1 teaspoon/day. I have noticed after taking it, I get a pump like never before. Haven't noticed much increase in strength yet. It is not controlled and I'm not advocating anyone to use, just wondering if anyone has heard of it.
