If you look this product up online, you will find a lot of praise for it because it used to have the Creapure seal of quality. You can still see the small Creapure logo up on the top right of Amazon's product thumbnail (the orange label is the old one; the label is now blue). Lesser quality creatine often contains toxic impurities due to incomplete synthesis. I bought this brand regularly because that logo meant it was chemically analyzed and guaranteed to be free of such impurities. I received a new shipment yesterday with fancy new label art, but the product no longer carries the Creapure logo. Be aware of this fact before you purchase this creatine. I returned mine because it was not what I expected.
