Harm reduction

The best way to avoid substance risk is to avoid drug use but that is not always possible. What always helps is nonjudgemental support and tools to improve safety – such as reagent test kits.

After years of research we are proud to present tests for over 800 psychoactive substances. Your safety deserves the best drug testing kit.

Frequently Asked Questions

What tests do you offer?

PRO Test kits help identify a substance and estimate it’s purity using just a tiny sample.

We offer both qualitative and semi-quantitative presumptive substance analysis test kits for MDMA, LSD, THC and 800+ other substances. Most of PRO Tests consist of colorimetric reagents similar to those used by the police, simple chemicals that change color upon contact with even trace amount of another substance. Reagents can be paired with TLC (Thin Layer Chromatography) kits to discover all ingredients and estimate amounts (potency). All PRO Tests are non-medical products, with the exception of repurposed fentanyl test strips.

For all PRO Tests you can find how-to videos (on product pages and Videos page), reference results web app and instructions (on product pages or in a booklet, also available as PDF both for reagents and for TLC.

QUALITATIVE TESTS

Those are mostly single-use / multi-use reagent that can indicate PRESENCE, but not QUANTITY. Mixtures can be detected with reagents only if adulterant causes a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit. With reagent tests you can:

1) Detect presence of a substance or confirm if it is not present at all
2) Detect most common adulterants even if the expected substance is also present

Multiple reagents are required to detect adulterants and increase analysis precision because there are more substances than colors.

Fentanyl tests strips on the other hand, if used correctly, can easily detect fentanyl even in the presence of other compounds.

All of the individual qualitative tests that we offer are: Cannabis (4-AP), Ehrlich, Froehde, Hofmann, Marquis, Mecke, Morris, Liebermann, Robadope, Simon’s, Zimmermann / Beam, TLC cannabis dye and fentanyl test strips. Reagents Mandelin and Scott have been discontinued and replaced by superior Morris reagent.

SEMI-QUANTITATIVE TESTS

These are the TLC tests to estimate NUMBER and QUANTITY of ingredients.

TLC purity tests separate a sample into different substances and also help estimate quantity. TLC tests don’t identify substances alone (unless you have an already confirmed reference sample) and work best paired with at least 1-2 reagent tests. At the moment you can precisely (with 10% error margin) estimate amount of cocaine, MDMA, THC, CBD and discover number of ingredients in 800+ other substances.
What drug testing kit do I need?
If you are new to drug checking we recommend one of our tailored per substance single-use tests (for 5.9€ with FREE worldwide delivery) or multiple-use test kits (about 20€ for 100 uses of several different reagents with free express shipping starting at 100€). If you want to know all ingredients and estimate potency add also a TLC purity test kit.

Reagents can indicate PRESENCE, but not QUANTITY. Adulterants can be detected with reagents only if they cause a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.

Cannabis (4-AP) – main test for THC / CBD, helps rule out synthetic cannabinoids

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

Froehde – main test for most powders, secondary test for ketamine and amphetamines, long shelf life

Liebermann – main test for most powders, secondary test for cocaine (detects levamisole)

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

Morris – main test for cathinones, cocaine and ketamine, can tell apart some novel dissociatives

Robadope – main test for primary amines, e.g. MDA, amphetamine or PMA

Simon – main test for secondary amines, e.g. MDMA, meth, mephedrone, methylone or PMMA

Zimmermann / Beam – main test for cathinones and benzodiazepines in geneal, detects also CBD

Reagents Mandelin and Scott have been discontinued and replaced by superior Morris reagent.

Fentanyl Test Strip to detect fentanyl, even if it is mixed in another substance.

To discover all adulterants and quantity pair reagents with a TLC Purity Test Kit. TLC tests enable you to separate sample into different substances and estimate quantity. TLC Purity tests alone don’t identify substances and are best paired with 1-2 reagent tests.

To test cannabis, we recommend the TLC Cannabinoid PRO Test. It doesn’t require additional reagents if you know whether your substance is THC or CBD dominant and shows all cannabinoids present and their ratios. A good combination or alternative is the CBD/THC Reagent Test Kit which can confirm whether sample is CBD or THC dominant, can rule out synthethic cannabinoids and helps compare CBD content of similar samples.

For all PRO Tests you can find how-to videos (on product pages and Videos page), reference results web app and instructions (on product pages or in a booklet, also available as PDF both for reagents and for TLC.
What are the expiry dates and storage requirements?
PRO Test kits will easily last you multiple years if stored correctly.

Single-use reagents last at least 3 years before any deterioration. Refridgeration not required. Keep out of sun in a cool dark place.
