Early on, Poliquin and those guys were using horse creatine from the livestock suppliers because of the cost. I wonder what the mix was on that, most were creatine and dextrose mixes before they became popular. That was one of the little secrets, BCAAs, DMSO, Creatine, Trenbolone, and a bunch of other things all came from the feed stores.
Not really all that interesting, but a little bit of history.
