GUIDE How to test Heroin (Opioids)?

How to test Heroin (opioids): if you intend to use a psychoactive substance first you need a test kit to check purity. Pure heroin can’t be identified by appearance. Check your sample with a single or multi-use heroin test kit.

Heroin tester

Single use heroin 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 heroin testing kits

Recommended multi-use Heroin Reagent Test Kit includes reagents Marquis, Mecke, Froehde and fentanyl test strips. Reagents are required to identify heroin or other opioids, while fentanyl test kit is irreplacable to detect presene of fentanyl, even if mixed in and present in trace amounts. To discover full ingredients and estimate heroin % pair reagents with the Full TLC Purity Test Kit. To detect fentanyl use the fent strips.

What are heroin test kit reagents used for?

SAMPLE	RECOMMENDED HEROIN REAGENT TESTS
HEROIN / CODEINE / O-DSMT / 2C-B / MDMA / MDA / METH/AMPHETAMINE	Marquis Mecke Froehde single-use heroin test kit multiple-use heroin test kit

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

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
Froehde – main test for most powders, secondary test for ketamine and amphetamines, long shelf life
Single use heroin test kit includes Froehde reagent
Multi use heroin reagent test kit includes reagents Marquis, Mecke and Froehde

Froehde reagent is the main test for heroin as it can tell it apart from codeine. It should not be used alone, requires Marquis and Mecke to confrm presence of specific opioids.

What is fentanyl?

Fentanyl is an extremely potent synthetic opioid with derivatives often from 50 to 100 times stronger than heroin. It is mainly responsible for the opioid epidemic overdoses. Fentanyl can be lethal even in doses invisible to a bare eye. It is often found in counterfeit medicine, opioid and non-opioid research chemicals or even common street drugs like cocaine.

When fentanyl is mixed with heroin, cocaine or other substances, it is never evenly mixed. Powder on one side of a baggy can contain no fentanyl, while powder from the other side might contain a lethal dose. It is extremely important to always test each and every dose intended for consumption.

How to use Opioids Reagent Test Kit?

GET ALL TOOLS

First, prepare a clean white testing surface – ceramic or glass is the best, e.g. bottom of a mug or a plate. Get your sample, reagents, a sharp tool / scoop and paper towels.

PREPARE SAMPLE, ABOUT THIS BIG -> ●

If testing a pill, powder or crystal, crush it finely. If testing a liquid, dry one drop on paper or clean ceramic surface. A bigger sample can cause a stronger reaction. You need a new sample for each test.

ADD ONE* DROP (OR PILE) OF REAGENT

Shake bottles hard before use, then tap firmly to shake down any reagent stuck in cap. Do not let a bottle touch sample or you will ruin the rest of the reagent. Use just enough reagent to cover a sample. If using crystals avoid air pockets by flattening crystals onto sample using a clean tool. *Do not combine reagents except for „A” and „B” bottles.

OBSERVE FOR UP TO 3 MINUTES*

Disregard any color change after 3 minutes. Do not overinterpret your results, consider that color change reaction is always fastest and most vivid in the part where biggest surface of reagent touches sample, compared to its edges. Over time reaction will degrade due to air contact. Take photos.

COMPARE RESULTS

Compare color change with instructions. 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.

Clean used reagent tools / testing surface with lots of running water and detergent, avoid contamination.

How to handle Opioids Test Kit?

Drug testing kits contain toxic and/or corrosive chemicals, strong enough to burn skin and clothing. Keep out of eyes and mouth. Keep away from children and animals. 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 lots of soap and water. Dispose of any unwanted reagent with running water, ventilate. Store reagents standing up and away from heat in a cool, dark place. The average shelf life of 2 years can be significantly extended by storing in a fridge or freezer (warm up to room temperature before use).

Reagents deteriorate with time or due to contact with air, especially if exposed to sunlight or not refrigerated. If you are uncertain whether the reagent will work, test it with an already confirmed sample.
How to test opioids for fentanyl?

Use fentanyl test strips (a fentanyl test kit)

METHOD 1

If testing a benzo/opioid pill, crush one in a plastic baggie 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.

STEP TWO How to test heroin 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 heroin purity pair a reagent test kit with the Full TLC Purity Test Kit.

How to test quality of heroin?

Qualitative TLC

TLC test works by separating substances present in a sample, each detected spot indicates a different substance.

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.

TLC Cocaine Purity Test potency scale

Reference adjusted from 66% pure cocaine with coffeine and ethenzamide. Due to UV-C light photo might not display correctly.

TLC MDMA Purity Test potency scale

Reference results ranging from 10% up to 100%, adjusted from lab confirmed pure MDMA hydrochloride sample

How to test quality of heroin?

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 use TLC purity tests?

Questions?

What is Full TLC Purity Test Kit for?

Full TLC Purity Test Kit includes best testing liquid and accessories for cannabinoids, cocaine, MDMA 2C-B but also suitable for ketamine, meth/amphetamine, opioids, phenethylamines, tryptamines and more. It is used to discover full ingredients and amount (%) of CBD, THC, MDMA, cocaine or 2C-B, DMT, LSD, ketamine, meth/amphetamine, heroin and to rule out caines, caffeine, cathinones, levamisol, PMA/PMMA or different, less predictable, less desirable, highly toxic dangerous drugs. Additional multi-reagent test kit is required to identify ingredients and increase analysis precision.
TLC purity test kits can detect NUMBER and AMOUNT of substances, but not their TYPE. Pair TLC test kit with reagent test kit to indentify ingredients. Reagents alone detect mixtures only if adulterant causes a darker color change than the expected substance.
What is included in Full TLC Purity Test Kit?

Full TLC Purity Test Kit includes instructions, gloves, 4 vials, 5 testing “cards”, jar, pipette, testing liquid (40 ml), 20 glass tubes, UV-C flashlight (4 AA batteries required, not included) and % rulers for CBD, THC, cocaine and MDMA. Each 1 “card”, 4 glass tubes and 4 ml of testing liquid equal 4 tests. Testing “card” can be reused untill fully used. Glass and metal protect testing liquid from air and moisture to ensure prolonged shelf life. High-quality caps and lid guarantee 0 spills.
TLC purity test kit for MDMA includes 3 testing liquid for MDMA, MDA, 2C-B, DXM, DMT, LSD, ketamine, caines, cannabinoids, caffeine, codeine, mCPP, meth/amphetamine, metoclopramide, paracetamol and other. It is best to use this test kit for cystals, powders, pills or plants.
How to use Full TLC Purity Test Kit?

GET ALL TOOLS
First, prepare a clean and well lit testing surfach. Get your sample, spatula, gloves, plastic vial, testing liquid, pipette, pencil, glass tube, wrapped esting cards, jar and UV-C flashlight. Next, carefully holding a testing “card” by only top edges mark 4 dots 1 cm apart from card’s bottom, sides and each other.
PREPARE SAMPLE
If testing a pill, powder or crystal, crush it finely. Weigh sample in a plastic vial and dissolve in testing liquid (or other solvent) using ratios mentioned in the booklet. Shake to dissolve. To big or too small sample can cause an inconclusive result.
ADD 1 MICROLITER TO CARD
In case of sediment wait a minute for it to fall down. Under strong light submerge end of glass tube to fill it with dissolved sample. Gently touch one of the marked dots on Testing Card to discharge sample and mark the spot with pencil.
INSERT CARD INTO JAR
Add 2 ml of testing liquid inside jar and carefully, paying attention to not touch the white side of Testing Card with sample, insert it inside jar. Close the jar and observe for about 25 minutes, until Testing Card almost fully soaks – but not any longer. Remove Testing Card from jar, wait for it to dry.
COMPARE RESULTS
Use UV-C flashlight to reveal results. Spots on Testing Card revealed by UV-C light circle using pencil. Each spot indicates a separate substance. TLC purity test kits can detect NUMBER and AMOUNT of substances, but not their TYPE. Pair TLC test kit with reagent test kit to indentify ingredients. Reagents alone detect mixtures only if adulterant causes a darker color change than the expected substance.
To reuse Testing Card do not apply reagent tests on it.
