Just 3 mg is enough to kill 1 person. It is best to not consume or at least reduce your intake of any substances containing Fentanyl.


Fentanyl Test strips by BTNX are the gold standard for at home testing for Fentanyl. Each test strip will come individually packaged and no additional equipment is required. All you need to simply do is dilute the powder or liquid with water, insert the strip, remove and wait 5 minutes.










Each order shipped from FentStrips.com comes with complete and comprehensive instructions on how to use them safely and effectively.


Some key tips to remember:


  1. Make sure to keep strips in packaging until ready to use

  2. Do not touch the end of the strip that will be inserted into the diluted solution to avoid contamination

  3. When possible use sterile water - this will reduce the instances of inconclusive results

  4. Test twice! Test until you get 2 conclusive results. Even though Rapid Response Fentanyl Testing Strips are >98% accurate, the more conclusive results the better

  5. Wait the full 5 minutes - a reaction with the reagent should be clear quickly but it could take up to 5 minutes
