** This product is highly perishable, and is kept refrigerated to ensure its maximum freshness. iHerb ships this item in an iced Styrofoam package, yet a small portion of its potency may be lost while in transit. Therefore, we recommend using an expedited shipping method, and placing your order during the first part of the week. If your order is placed on Monday through Wednesday before 1pm PST your order will be shipped the same day. Otherwise your order will be held until the following monday for shipment. Also if you order on Thursday by 1:00 pm (PST) it will be shipped if you have chosen a next day shipping method. Orders placed on Friday will be held and shipped out on Monday. If that is a problem, you might consider purchasing a stabilized form instead. Note to International Customers: iHerb is unable to ship this product in an iced, insulated package for destinations outside of the United States. Thus, we strongly recommend that you purchase a stabilized form as a substitute.
