Shipments containing probiotics will be released Monday-Wednesday. 2nd Day Air shipping is recommended. We will not automatically restrict your shipping choices, and will honor the method selected. However, please understand that failure to select an expedited shipping speed verifies that you are assuming full responsibility for the condition of the delivered product.
