SKU: STRP-FYL Category:


Fentanyl is an extremely potent opioid drug sometimes sold in place of benzodiazepines, heroin and other opioids. It can be pressed into tablets or sold as a powder and in its undiluted form a fatal dose is the size of a grain of sand. Fentanyl is regularly found in the US and Canada but much less common in Europe

This contains two single-use strips. This page contains adult content: Drugs.

The single-use strips are used by dissolving a tenth of a dose into a tablespoon (15 mL) of water and submerging the test strip to the line. The test will detect any amount of fentanyl which could have an effect. For powders which may not be evenly mixed, dissolve the whole sample into 100mL of water and perform the same test. You can recover the sample by evaporation. Please contact us if you get a positive result.

Lateral flow assays are able to detect a range of fentanyl analogues. Detects fentanyl at concentrations over 0.01 μg/mL. Detects 4-FiBF, Furanylfentanyl and Acetylfentanyl over 1ug/mL (sufficient to detect dangerous amounts). We do not sell the tests to detect in urine but they are able to do this.

As with all harm reduction techniques, testing does not guarantee safety – even pure heroin, MDMA, cocaine etc can be fatal. Make sure you don’t just test for the presence of fentanyl. Never take a full dose as your first dose from a new batch.
