Fentanyl and fentanyl analogs are highly potent synthetic opioids a hundred times stronger than heroin or more. They are largely responsible for the dramatic increase in drug overdoses worldwide. Fentanyl overdoses have been linked to counterfeit pharmaceutical pills (painkillers like Vicodin or Percocet and benzodiazepines like Xanax or Valium among others) that contain fentanyl, as well as fentanyl-laced cocaine, heroin, and MOST other substances.

If you did not obtain the substance from YOUR PHARMACIST, then it MUST be tested for fentanyl at this point.

IMPORTANT: When fentanyl (or a fentanyl analog) is mixed with heroin, cocaine or other substances, it is *never* mixed evenly. Powder from one side of a baggie may contain no fentanyl at all, yet powder from the other side may contain a fatal dose. It is important to test every bit of the substance you intend to consume, before you consume it.

Please use fentanyl test strips along with our spot kits / separation kits in order to thoroughly evaluate your sample. Fentkits are specifically designed to detect fentanyl and its analogs. They cannot detect other dangerous adulterants.

 

ABOUT OUR FENTANYL TESTING STRIPS

Our fentanyl testing strips have been thoroughly evaluated by a team of researchers at the University of California San Francisco as well as at our own laboratory in the European Union. They are capable of detecting incredibly small amounts, even traces, of fentanyl along with many of its known analogs – including acetyl-fentanyl and carfentanil.

These kits (along with every other kit on the market) have limitations. There is no method available today capable of detecting every fentanyl analog. The version available on this site covers the most common and dangerous versions – more than any other on the market.

Our strips have been verified to positively identify the following:

Fentanyl — 200 ng/
Carfentanil — 1,000 ng/ml
Butyryl Fentanyl — 700 ng/ml
p-Fluoro Fentanyl — 200 ng/ml
Acetyl Fentanyl — 150 ng/ml
Furanyl Fentanyl — 500 ng/ml
Valeryl Fentanyl  — 700 ng/ml
Ocfentanil  — 250 ng/ml
3-Methyl Fentanyl  — 500 ng/ml
Remifentanil  — 70,000 ng/ml
Sufentanil  — 100,000 ng/ml

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. Five different strips from three different manufacturers have been evaluated by UCSF. Four did not detect carfentanil and one set of strips from a Chinese manufacturer did not work at all. DO NOT TRUST TEST STRIPS THAT DO NOT CONTAIN BOTH ANTIBODIES. THIS IS INCREDIBLY IMPORTANT.

 

TESTING COCAINE, MDMA, KETAMINE, AND OTHER NON-INJECTED SUBSTANCES

Method #1 – Testing everything you intend to consume

The BEST method for testing non-injected substances—including powders, crystalline or tablets—is to test every bit of the substance you intend to consume. This requires dissolving the whole sample in water first. You can still consume the sample by drinking the water or you can let the water evaporate and consume the substance later. Evaporation could take anywhere from a few hours to a few days, depending on heat and humidity, but will not effect your substance.

 

 

  1. Place all of the substance you intend to consume into a shallow glass or ceramic cup. (Tablets or crystals must first be crushed into a powder.)
  2. Add enough clean (preferably distilled) water into the cup to COMPLETELY dissolve the crystals or powder.
  3. Stir thoroughly with a clean spoon or other utensil.
  4. Hold the blue end of the test strip and insert the other end into the liquid, NO HIGHER THAN THE BLUE LINE.
  5. Allow the liquid to travel up the strip into the test area. (This takes about 15 seconds.)
  6. Set the strip down on a flat surface and wait about two minutes. See “Interpreting The Results” below.

Method #2 – Testing the residue inside your baggie.

CAUTION! This is NOT the best method for testing cocaine or other non-injected substances. The best method is to test every bit you intend to consume as described above. However, we are including this method here because we recognize that some people may not have the ability each time to dissolve all of the substance they intend to consume in water. This method has a higher chance of producing false negatives. (See “The Most Important Thing You Need to Know About Fentanyl” above.)

 

 

  1. Fill your baggie with clean (preferably distilled) water and swish it around to dissolve the residue.
  2. Pour the liquid-residue into a shallow, clean glass.
  3. Stir to dissolve any crystals or clumps.
  4. Hold the blue end of the test strip and insert the other end into the liquid, NO HIGHER THAN THE BLUE LINE.
  5. Allow the liquid to travel up the strip into the test area. (This takes about 15 seconds.)
  6. Set the strip down on a flat surface and wait about two minutes. See “Interpreting the results” below.

Method #3 – testing heroin and other injected substances

If you inject, you need to test every time you do so. The best method is to test the residue from your spoon or cooker. After preparing your shot, set the needle aside and wait to inject.

 

 

  1. Add a small amount of clean (preferably distilled) water into the spoon or cooker. (1 millimeter or 1/4 teaspoon is enough.)
  2. Use the bottom end of a clean needle to swish the water around inside the spoon or cooker
  3. Hold the blue end of the test strip and insert the other end into the liquid, no higher than the blue line.
  4. Allow the liquid to travel up the strip into the test area. (This takes about 15 seconds.)
  5. Set the strip down on a flat surface and wait about two minutes. See “Interpreting The results” below.

TESTING MDMA

If there is too much MDMA in a tested sample, it may return a FALSE POSITIVE for fentanyl. To make sure this does not happen, test a dose of MDMA (100mg) in at least ½ cup of water.

INTERPRETING THE FENTKIT TEST RESULTS

One red line on top is a POSITIVE result for the presence of fentanyl or one of its analogs. Two red lines is a NEGATIVE result – this is what you want. No red lines (or one red line on the bottom) means the test is invalid. (Usually this happens because the liquid did not travel far enough up the testing strip.
