Our updated fentanyl test strips are the most accurate, cutting-edge, and widely approved fentanyl test strips on the market. Manufactured by W.H.P.M., these new strips can detect fentanyl and most of its known analogs in any drug sample, and unlike other strips (such as the older, BTNX strips), they do not produce false positives with meth, MDMA, or cocaine that contains levamisole. They can also be used to test pressed ecstasy tablets. These strips utilize a superior antibody with greater specificity to fentanyl, and as a result, are the most reliable strips on the market for drug checking and harm reduction purposes.

Includes:

• Single-use fentanyl testing strips
• Includes thorough instructions for use
• Packaged in a mylar envelope
• Free shipping when purchased alone. Please note, if you add any other products into your cart, standard shipping rates will apply to those items.

Please read the instructions carefully. These strips work differently than the older, BTNX strips. For dilution ratios and more information, see our How to Test Fentanyl page.

CAUTION! Fentanyl test strips from other sources may not detect all necessary fentanyl analogs. Some versions (mostly of Chinese origin) may not function at all.
