LSD QTest – The world’s first and only potency test kit for accurately measuring LSD contents in blotters and liquids

The potency of LSD blotters or liquids can vary tremendously. Studies have shown that many LSD products contain only half of the expected potency, or include other synthetic compounds like DOB or NBOMe. This is exactly why we developed the LSD-QTest, the world’s first scientifically validated do-it-yourself test kit for measuring LSD concentrations.


With this test, you can easily determine the potency of LSD-25 in liquids or blotters within minutes. Results are given as precise microgram (µg) amounts of LSD-Tartrate. Simply use a half blotter or one drop of your liquid to measure the exact LSD concentration. You can easily read the result by comparing your sample with the supplied color scale. The scale fits every blotter from weak to very strong and also tells you how much µg LSD is in one drop of your solution.



Key Features of Our Test Kit:

  • Rapidly know how strong your blotter/liquid is
  • Minimal sample required, user-friendly testing
  • Just test a small sample to know the potency of the rest
  • University-validated method
  • The only quantitative LSD test on the market

Frequently Asked Questions about the LSD-QTest


Do I need anything else to perform the test?

Everything you need is included in the box.

To prepare your sample, you only need the following, which you probably already have at home:


  • A scissor to cut your blotter in half
  • A pipette/dropper to measure a drop from your liquid

How much material do I need for the test?

You only need a half of a blotter or one drop of your liquid to perform the test. Liquid LSD tends to settle at the bottom of the vial, for reliable results it is important to shake/invert your liquid carefully before testing. The result will tell you how much LSD-25 is in the tested sample. Remember that if you test it from a blotter to calculate the total amount of LSD-25, you need to multiply the results you get in the color chart by two.


Does the QTest also work for derivatives such as 1 cP-LSD, 1P-LSD, or similar?

Our LSD-QTest is calibrated to  LSD-25 and measures its concentration. The test does not react to derivatives like 1P-LSD, 1cP-LSD, ALD-52 or ETH-LAD, or others. If your blotter/liquid contains only these, the test will not show any coloration.


What does quantitative test mean and how does the QTest differ from “classic” reagent tests?

Our QTests are more powerful than classic reagent tests. While reagent tests detect the presence of an active ingredient in a substance, our QTests quantify it. This means they determine the concentration of active ingredients in various psychoactive substances, such as in blotters or liquids.


What is the shelf life of the QTest,  and how should I store it?

Store the reagents at room temperature (35 - 68 °F) out of direct sunlight for a shelf life of at least 18 months. If possible: it is best to store chemical reagents chilled in the refrigerator.

Verification & Testimonials of the LSD QTEST


What others say about our QTest:

The functionality and the precision of our QTests have already been tested & validated by a lot of customers and third parties:


The Beckley Foundation, a forefront of global drug policy reform and scientific research into psychoactive substances supports our QTests straight from the beginning.


Psychedelic Passage compares the results of our rapid tests with laboratory tests from Energy Control International (a long-standing drug-checking program in Spain) for identical samples and comes to convincing results:

  • LSD-QTest Result: We determined that the color was much closer to the 50ug color range than the 25ug and concluded that the sample likely contained about 40ug of LSD-25. 
  • LSD Lab Test Result: The lab test indicated that our sample contained 43ug of LSD tartrate.

The QTest where officially validated & approved for the federal drug-checking program ALIVE in the federal state of Thuringa (Germany).
