<unk>  (aka Carcalon, creatine, substance X, or drug X) is a disproven cancer treatment that is made available as an alternative cancer treatment. While the substance has been marketed as a cure for cancer, originally sold for thousands of dollars per dose in the 1950s and early '60s,<unk>  is not known to possess any therapeutic value. Attempts to analyze its composition have shown that<unk>  consists only of the amino acid creatine dissolved in mineral oil, and some samples sold as<unk>  consist solely of mineral oil with no other discernible ingredients. The American Cancer Society states: "Available scientific evidence does not support claims that<unk>  is effective in treating cancer or any other disease." According to the U.S. Food and Drug Administration (FDA),<unk>  has been linked to several dangerous side effects.
