To begin testing, scrap a grain of pill or powder and drop the reagent onto it. A positive result will show as a color changing reaction. No reaction is caused by Caffeine but also many other substances or lack of active ingredient. CHECK TESTDRUGS APPS –

Storage Instructions:

The reagents should be stored in a freezer, where they will last at least 24 months. Unfreeze/warm to room temperature before use. Keep the test away from the sun in a cool, dark place.


Most reagents are primarily concentrated acid with other potentially dangerous chemicals and are strong enough to burn skin and clothing. Keep out of eyes and mouth. Keep away from children. Always use in a well-ventilated area. Wear gloves (supplied) when handling the bottle and cap. Wear protective eyewear. Never point towards face etc. If you get some on you/clothing, then immediately wash with soap and water. Wash testing surfaces with soap and water as well. Dispose of any unwanted reagent down the sink with running water and Baking Soda (supplied), ventilate. Store all testing kits away from any heat in a cool, dark place between uses.

A positive or negative reaction for a substance does not indicate that it is safe. No substance is 100% safe.
