Product Storage Guidelines

Please note these products need to be kept cool to maintain their potency. However, they are stable at room temperature for 5-7 days. If your product arrives warm, it is NOT damaged, as it was cold when it left our warehouse. For best results, keep all products out of direct sunlight.
