How to test LSD?

How to test LSD: if you intend to use LSD (“acid”, first you need an LSD test kit to check it for adulterants. Pure LSD can be laid on any kind of blotter paper (or other material) and can’t be identified by appearence. To test LSD use reagent tests Ehrlich, Hofmann, Marquis and Mecke in single-use or multiple-use test kits. To detect all ingredients and estimate potency it’s required to use additional purity test kitsTo detect fentanyl or test for fentanyl analogs it’s recommended to use fentanyl test strips.

How to test LSD using reagent tests?

Watch our video on how to test LSD with Ehrlich reagent and Hofmann.

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 kitA positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.

SAMPLE RECOMMENDED LSD TEST KITS
LSD / DMT / tryptamines,
lysergamides, other indoles

How can I test LSD?

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.
  • Put it on a suitable testing plate, preferably a spot test plate or the bottom/underside of a ceramic mug (example). *If using single-use vials insert the sample and observe, as the reagent is already within.
  • Add one (or two) drops of Ehrlich reagent test (or other supplied) on the sample and wait for the results.
  • Check reagent test results with instructions.

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

Only if your tab doesn’t change color within 10 minutes (like this example):

  • To double check Ehrlich test result  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 Erowid.org.
  • IF HOFMANN DOESN’T REACT EITHER 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.

Next choose a purity testing kit. It enables you to detect all sample ingredients at once, however still requires reagent tests to identify substances.

  • To estimate amphetamine 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.

AFTER using an LSD test kit

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

FAQ

  • 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.
  • If Hofmann reagent doesn’t react, allow 5-10 more minutes for the reaction to develop. Hofmann test is known to react more slowly than Ehrlich reagent, so it’s safe to assume that even if in the first couple of minutes just the blotter turns blueishl that’s also a positive reaction.
Testing LSD with Ehrlich reagent and Hofmann

 

  • 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).

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.

How can I detect fentanyl?

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.

STEP ONE FOR TESTING FENTANYL POWDER / PILLS / SPICE

  • Dissolve 100-200 mg in at least 125 ml of water (half a cup).
  • Grab a test strip by blue end and insert it into the liquid, no higher than the blue 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.

HOW TO USE A FENTANYL TEST STRIP?

  • Check test strip results: a single line confirms the presence of fentanyl, while two lines (even faint) rule it out.

Next choose a purity testing kit. It enables you to detect all sample ingredients at once, however still requires reagent tests to identify substances.

FAQ

  • Faint line. Even faint second line result is enough to rule out the presence of fentanyl.
  • Injecting. If you inject you especially need to test each and every dose. It’s best to test the spoon (or cooker) residue every time before use.
  • Speed of the reaction does not indicate quantity nor purity. However, if you are having trouble interpreting your result try using a bigger sample or crushing it better before testing.
  • How many tests can you get from one test kit? A single fentanyl test strip is enough for one test.
