GUIDE How to test LSD?

How to test LSD (Acid): if you intend to use a psychoactive substance first you need a test kit to check purity. Pure LSD can come in the form or blotters, gel tabs, sugar cubes or crystals and can’t be identified by appearance. Check your sample with a single or multi-use LSD test kit. 

LSD tester

Single use LSD tester available with free shipping. This test gives the least amount of information and should be used with extra caution. Read about more advanced tools further down.

Recommended LSD testing kits

Recommended multi-use LSD Reagent Test Kit includes reagents Ehrlich, Hofmann, Marquis and Mecke. Ehrlich and Hofmann are required to identify LSD, while Marquis and Mecke help identify the adulterant in the case of absence of LSD. To discover full ingredients and estimate LSD % pair reagents with the Full TLC Purity Test Kit. To detect fentanyl use the fent strips.

What are LSD test kit reagents used for?

SAMPLE RECOMMENDED LSD REAGENT TESTS
1B-LSD / 1V-LSD / 1P-LSD / DMT / 5-MeO-DMT / 
OTHER LYSER GAMIDES AND TRYPTAMINES / METH/AMPHETAMINE
 

Reagent tests indicate presence of a substance, therefore can either help confirm presence of the expected compound or help rule out certain cuts.

  • Ehrlich – main test for all indoles, e.g. lysergamides and tryptamines but also 5-HTP and more, secondary test for cocaine
  • Hofmann – main test for lysergamides and tryptamines, more precise but slower than Ehrlich
  • Marquis – main test for most powders, secondary test for ketamine, mephedrone and psychedelics
  • Mecke – main test for most powders, secondary test for cocaine, ketamine and mephedrone
  • Single use LSD test kit includes Ehrlich reagent
  • Multi use LSD reagent test kit includes reagents Ehrlich, Hofmann, Marquis and Mecke

Ehrlich reagent in the main test for all indoles, such as LSD or DMT but also other lysergamides, tryptamines, even melatonin, tryptophan or 5-HTP. Hofmann reagent helps narrow down indoles to LSD or DMT. Reagents Marquis and Mecke help detect adulterant in case LSD is not present and also can test other compounds.

How to test LSD gel tabs?

LSD gel tabs can severly interfere (cause false positives) with Ehrlich reagent, therefore it is required to focus on Hofmann reagent to test LSD gel. More information in our article here: How to test LSD gel tabs?
 

How to detect NBOMe?

Basing on lab analysis data (source: drugsdata.org) If Ehrlich and Hofmann confirmed presence of LSD you can assume there is almost no change an adulterant, like NBOMe or DOC is present too. That doesn’t make sense to dishonest dealers financially. In case Ehrlich and Hofmann ruled out presence of LSD, follow up with Marquis reagent and Mecke and check for any instant and vivid color change.

STEP TWO How to test LSD purity %?

To discover all adulterants and estimate quantity pair reagent tests with a TLC (Thin Layer Chromatography) Purity Test Kit. TLC purity tests alone don’t identify substances and are best paired with at least 1-2 reagent tests. Thin Layer Chromatography is one of classic substance analysis methods. It works by separating different compounds depending on their solubility in chosen TLC testing liquid (eluent). To precisly estimate LSD purity pair a reagent test kit with the Full TLC Purity Test Kit.

How to test quality of LSD?

 
Qualitative TLC:

TLC test works by separating substances present in a sample, each detected spot indicates a different substance. In case of LSD you can detect iso-LSD (iso-n,n-diethyl-d-lysergamide) and other degradations products, as well as phenethylamines like NBOMe and DOC. Source: Analysis of Preparations Containing LSD (N,N-Diethyl-d-Lysergamide) by Robert J. Martin and Thomas G. Alexander in Journal of the A.O.A.C, vol. 50, no. 6, 1967).  

 
  • You can use an already confirmed sample for reference – if both compounds show up at the same height on the TLC “card” that indicates they can be the same substance.
  • You can use any substance for reference after establishing their relation – if substance X shows up twice as high on the same testing “card” as substance Y, you can expect them to keep that ratio.

How to test quality of LSD?

 
Semi-quantitative TLC:

TLC 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 and often different testing liquids (eluents).

  • One spot indicates a pure substance. If your sample fully dissolved in testing liquid and only one spot was detected on TLC then your substance is pure. Trace amounts of impurities might not be detected, do not rely on TLC for fentanyl testing – get also fentanyl test strips

How to test LSD for fentanyl?

Use fentanyl test strips (a fentanyl test kit)

Fentanyl test kit instructios

METHOD 1   

If testing a blotter or gel tab put it in a plastic baggie. If testing a pill crush it in the baggy and dump out the powder.  Then add 10 drops of water into the baggie and mix well. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.

METHOD 2

Mix 100 mg of sample in 200 ml of water. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.

COMPARE RESULTS

1 line = fentanyl, 2 lines = no fentanyl. Faint lines also count. Ignore fentanyl tester results after 5 minutes.

To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.

Check all PRO Test guides how to test drugs.

 

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