Instructions for Testing Liquids & Powders
BTNX Fentanyl Testing Strips are an effective way to test powders and liquids for the presence of fentanyl. According to a 2018 John Hopkins University Study, BTNX test strips were able to identify analogues of fentanyl with 98% accuracy.
DISCLAIMER: THE ONLY WAY TO MAINTAIN ACCURACY IS TO TEST THE ENTIRE SUBSTANCE TO BE CONSUMED. TESTING A SAMPLE IS JUST THAT - TESTING A SAMPLE. FENTANYL COULD BE UNEVENLY DISTRIBUTED SO THIS IS THE ONLY WAY TO GET A RELIABLE RESULT
