Think all creatine is the same? It’s just not so anymore. Some greedy companies are using less pure sources and flooding the market with inferior, ineffective creatine.

They manufacture creatine under patent 5,719,319 and are the only producer of creatine that has registered a drug master file on creatine with the FDA. Pfanstiehl creatine is kosher certified and they utilize state of the art HPLC analysis. This analysis coincides with their zero tolerance for impurities and by-products.
