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 Tests help identify a substance and estimate its purity using a small sample, approximately this big -> ●

We offer both qualitative and semi-quantitative test kits for the presumptive analysis of cocaine, LSD, MDMA, THC, and 800+ other substances.

QUALITATIVE TESTS (for identification)

These are tests for checking the PRESENCE of a substance, but not its concentration (POTENCY) or PURITY.

Colorimetric identification tests can only detect an adulterant if they react with a more characteristic (dark) color than the expected substance. To increase the accuracy of the test, it is crucial to always use several different reagents from the kit.

Test strips, when used according to the instructions, can detect substances even in trace amounts.

SEMI-QUANTITATIVE TESTS (potency and purity)

These are tests for estimating concentration (POTENCY) and PURITY. The difference is that purity testing also detects impurities in addition to concentration. Potency and purity tests should be used after tests for identification.

Colorimetric concentration tests change color depending on concentration, should be used after identifying substance and ruling out cuts.

TLC purity tests allow you to separate different substances in a sample and estimate the quantity. TLC tests do not identify substances on their own (unless you have a previously confirmed sample for comparison) and work best when combined with colorimetric reagents.
What are the differences between tests for identification?
To compare reagents, check the table below. A ➕ sign indicates confirmation of the expected substance; at least two are recommended. A ➖ sign indicates exclusion of specific admixtures. A blank field indicates no use.

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 mixed in another substance.

Nitazene Test Strip to detect nitazenes, even mixed in another substance.

Xylazine Test Strip to detect xylazine, even mixed in another substance.

Reagents for identification can indicate PRESENCE, but not QUANTITY. Mixtures can only be detected with reagents if the additive causes a darker color reaction than the expected substance. Test strips can detect PRESENCE in any sample. To detect all components and estimate their quantity, combine the test strips and identification reagents with a TLC purity test.
What are the expiry dates and storage requirements?

The avarage best before data for our products is 2 years after purchase. Multi-use reagent bottles can be frozen or kept in a fridge to extend their shelf time, but it is not required. If you choose to chill reagents, make sure to thaw and warm up to room temperature before use.
