To use Quick Luck, do not break the safety seal until the day of your drug test to prevent bacteria growth. On the test day, warm the urine between 94°F and 100°F using the included heating pad. If needed, use the heat activator powder for quick heating. Shake gently after adding the powder to mix well. Attach the heat pad to the bottle, hide the bottle discreetly on your body, and use the flip-up spout cap to pour into the testing cup during the test.
