Dual LSD Test Kit comes with 2 single-use reagents for „Acid” as well as its common adulterants. It is used to positively identify LSD, 1P-LSD, AL-LAD, ETH-LAD, ALD-52 and to rule out 2C-B, NBOMe, N3OMe, NBOH, NBF, DOx, and different, less predictable and less desirable, highly toxic dangerous drugs. Multiple reagents are required to detect adulterants and increase analysis precision.

The Dual LSD Test Kit instructions and apps feature over 100 substances. Each single-use vial contains 0,2 ml (4 drops) of a reagent. Glass protects reagents from light, plastic, and moisture to ensure prolonged shelf life. For extra-stealth ask us in the checkout notes to remove substance-related stickers and fliers.

SIN Dual LSD Test Kit consists of 2 reagents: Ehrlich and Hofmann (2 tests total). It’s best to use this set for LSD or DMT, but it’s also a good test for all lysergamides and tryptamines.

NOTE: Reagents deteriorate with time, especially if exposed to sunlight or not refrigerated. If you are uncertain whether a reagent will work, test it with a previously checked sample.

NOTE: Dual LSD Test Kit can only test the PRESENCE, not PURITY or QUANTITY of a specific substance. Always test under a strong light and using the smallest possible sample. Never open more than 1 bottle at once, if you make a mistake you might contaminate the reagents and spoil them. If a few reactions are happening at once, only the darkest one of them will be visible.

TL;DR: Here is an image with a quick cheat sheet how to use the LSD test kit, or check out more detailed guide on how to test LSD further below.

How to test LSD? Instructions how to use the LSD Test Kit. This is the same instruction chart for reagent tests Ehrlich, Hofmann, Marquis and Mecke as in the guide How to detect NBOMes or DMT test kit.

BEFORE using an LSD test kit

  • It’s RECOMMENDED to record the reaction to compare later

STEP ONE for testing LSD blotters / tabs / crystals

  • Take a (small) corner of your tab.
  • Carefully open a vial and using included spatula move the sample into the vial.
  • Wait for the results and check instructions.
  • Dispose of safely.
How test LSD with Ehrlich reagent and Hofmann test, how much LSD to use for testing
How to test LSD? Myth: Reagent test wastes a lot of LSD. In reality on the contrary, use the smallest samples possible to cut off. LSD is usually evenly distributed. Who can test less?

How to use an LSD test kit?

  • Check test results with Ehrlich test kit: if testing LSD the exact color of the reaction is not important – the test is of a yes/no type. It will go purple or pink if it is exposed to an indole compound like LSD, an analogue of LSD or a tryptamine. No 0.5cm² blotter can fit an active dose of tryptamine onto it.
  • NBOMe compounds and other phenethylamines (like 2C-B) will not give a colour change with the Ehrlich reagent.

STEP TWO testing LSD for adulterants

According to, LSD tabs are never ‘adulterated’ with something else besides the main component. Dangerous substances missold as LSD, like 25I-NBOMe responsible for many deaths, do not react with Ehrlich and Hofmann reagents, contrary to LSD and other lysergamides. Only if your tab doesn’t change color within 10 minutes (like this example):
  • THEN in addition to this it is good to use test kits Marquis, Mecke or Froehde. These do make the paper go brown but if there is something like DOC present then the liquid itself usually gives a pretty vivid green colour change.
  • In case of doubt that Ehrlich test result could be a false positive, use Hofmann reagent to test more specifically for LSD and tell it apart from other indoles. It’s more precise than Ehrlich, but reacts slower. Keep in mind that other reagents are much less accurate/reliable, according to
Ehrlich Reagent and Hofmann Reagent
Basic LSD reagent tests differences: Hofmann reagent reacts slower than Ehrlich. If blotter seems to turn blue/dark this is still a positive result and indicates the presence of LSD.

AFTER using an LSD test kit

  • OPTIONAL: Pour baking soda over a finished reaction to neutralize used reagents.
  • Wash testing surface under running water.


  • BITTER tasting tabs. Just because a blotter/tab tasted (slightly) bitter doesn’t mean that it wasn’t acid. Ink can be bitter but so are many other chemicals. Hofmann himself in his notes wrote pure LSD-25 has a slight bitterness.
  • False positives. To check if Ehrlich test result could be a false positive, use Hofmann reagent to test more specifically for LSD and tell it apart from other indoles. It’s more precise than Ehrlich, but reacts slower.
  • Speed of the reaction does not indicate quantity nor purity. However, if you are having trouble interpreting your result try using a bigger sample.
  • How many tests can you get from one test kit? A multiple-use test kit lasts up to 100 (5 ml) or 200 (10 ml) tests. Each drop equals one test. A single use-test kit contains 2 disposable ampoules (2 tests).

All LSD test results:

MARQUIS No reaction (charcoaling paper)
MECKE No reaction (charcoaling paper)
MANDELIN No reaction (charcoaling paper)
LIEBERMANN No reaction (charcoaling paper)
FROEHDE No reaction (charcoaling paper)
EHRLICH Pink > Purple > Blue
HOFMANN Blue > Dark Blue
SIMON’S No reaction
ROBADOPE No reaction
SCOTT No reaction
ZIMMERMANN No reaction

LSD test did not react as indicated? Watch out!
All test results are available in our instructions and TestDrugs apps.

How to check if reagent for testing LSD works?

  • Test any substance and compare color reactions with instructions. It’s easiest to use 5-HTP or melatonin with Ehrlich reagent, which should turn pink / purple or blue.
  • Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.

Reagents consist mostly of concentrated acid and are strong enough to burn skin and clothing. Keep out of eyes and mouth. Keep away from children. Always use in a well-ventilated area. Wear gloves (supplied) when handling the bottle and cap. Wear protective eyewear. Never point towards face etc. If you get some on you/clothing, then immediately wash with soap and water. Wash testing surfaces with soap and water as well. Dispose of any unwanted reagent down the sink with running water and baking soda (supplied), ventilate. Store all testing kits away from any heat in a cool, dark place between uses. The average shelf life of 1 year can be significantly extended by storing in a freezer (warm to room temperature before use).

A positive or negative reaction for a substance does not indicate if it is safe. No substance is 100% safe.

  14. eBay Buyer c***0

    Defective item, most of the bottles were empty! Seller is trying to sell air! 🙁

    SIN response: We are very sorry to hear you are having trouble with your purchase. The “proof” showed only NON-EMPTY vials, with enough reagent for the advertised single use. We refund any mistake if there is evidence, but in this case buyer seems to have confused single-use with multiple-use. Single-use vials are ALMOST empty, unlike the multiple-use bottles that are also available on separate listings.
