The physical testing materials in the Test Kit do not expire, and the Shake is shelf stable and does not require refrigeration. Simply verify the expiration date printed on your Shake bottle before consuming. However, once you register your Test Kit a lab order is created and your samples must be completed and submitted within 5 months. If samples are submitted outside of this window the lab may encounter issues with processing your samples. If you have any questions about taking your Nutrition Test, or cannot complete it in time, please Contact Us.
