How to test FENTANYL?
GUIDE How to test fentanyl?
How to test fentanyl: reduce risk by using a fentanyl test kit to rule out presence of this dangerous adulterant. Fentanyl can be even 100 times more potent than morphine and therefore is easy to accidentaly overdose on. Fentanyl can be mixed in any kind of sample and can’t be identified by appearance. To detect fentanyl or test for fentanyl analogs use the fentanyl test strips. To test other substances use reagent tests, simple chemicals that indicate presence of a substance by reacting with different color change to different substances. To test you need just 1 drop of a reagent and a small sample, about this big -> ●. To detect all ingredients and estimate potency it’s required to use an additional substance purity test kit.
Reagents presumptively indicate PRESENCE, but not PURITY or QUANTITY. Use different reagent tests to improve accuracy and to detect adulterants – 90% of adulterants will react with 1 out of 3 tests and 95% with 1 out of 5. To detect all ingredients and estimate potency it’s required to use an additional purity test kit. A positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.
How can I test fentanyl?
Short instructions:
BEFORE using a fentanyl test kit
- It’s RECOMMENDED to test each and every dose. Because of extreme potency (microgram range) fentanyl is never evenly mixed in. One part of a baggie can be fentanyl free and another lethal.
Fentanyl testing instructions
- Dissolve 100 mg in at least 125 ml of water (at least 1 ml/mg).
- Dip the test strip no higher than the thick line.
- Wait up to 15 seconds water moves up the strip.
- Check results in 2 minutes.
- Consider using the TLC Substance Purity Test Kit to double check possible adulterants and estimate potency.

STEP ONE How to identify fentanyl?
What is fentanyl?
Fentanyl is an extremely potent and dangerous synthetic opioid, often mixed in street drugs and deadly.
BEFORE using a fentanyl test strip
- It’s RECOMMENDED to test each and every dose. Because of extreme potency (microgram range) fentanyl is never evenly mixed in. One part of a baggie can be fentanyl free and another lethal.
How to test fentanyl powder / pills / spice with a fentanyl test strip?
- Dissolve 100 mg in at least 125 ml of water (half a cup or at least 1 mg/ml).
- Grab a test strip and insert the white end into the liquid, no higher than the thick line.
- Wait until liquid starts visibly moving up the test strip (up to 15 seconds).
- Put the test strip away on a flat dry surface and read the result in 2 minutes.
- Check test strip result: a single line confirms the presence of fentanyl, while two lines (even faint) rule it out.

STEP TWO How to test substance purity?
According to the EMCDDA and drugsdata.org fentanyl is most often found in opioids and sometimes in stimulants, like cocaine, MDMA or meth/amphetamine.
Choose a purity testing kit. It enables you to separate sample into different substances and estimate quantity, however still requires reagent tests to identify detected substances. To discover all adulterants and quantity pair reagents with a TLC (Thin Layer Chromatography) Purity Test Kit. Purity tests alone don’t identify substances and are best paired with 1-2 reagent tests.
TLC Purity Tests:
- Qualitative: One spot indicates a pure substance. TLC test works by separating substances present in a sample in order to reagent test them individually. You can also use an already confirmed sample for reference – if both compounds show up at the same height on the TLC “card” that indicates they are the same substance.
- Semi-quantitative: TLC also helps estimate quantity (potency). The bigger the size of the detected spot, the bigger the amount of measured substance. Note that different substances need different calibrated rulers.
TLC Purity Test potency scale
- To estimate sample purity (number of ingredients and their concentration) use the Substance Purity Test Kit.
- To precisly estimate MDMA purity use the MDMA Purity Test Kit, which in addition includes a calibrated plastic ruler.
For full TLC (Thin Layer Chromatography) instructions read our guide how to test drugs purity.

HARM REDUCTION
A positive reaction does not indicate if the substance is safe. Remember to avoid mixing with other drugs, take care of yourself and take breaks. Ketamine can be habit forming and is known to cause bladder damage in those cases, therefore regular use can be particularly dangerous. Learn more at erowid.org.
