Heroin Testing kit
Can Only Afford One?
We recommend a single bottle of our Marquis Reagent. If the substance you are testing is Heroin a red-purple.
We Never Use Just One.
We've put together this custom package of drug testing reagents that test positive for Heroin. This kit is great for detecting those nasty adulterants that are often sold as Heroin. Testing with multiple tests will also help prevent false positives.
