EZ Test LSD and Indoles — Know What's on Your Tab
EZ Test LSD and Indoles is a single-use reagent test kit that detects the presence of LSD and other indole compounds in a sample within minutes. Drop a tiny amount of your substance into the phial, give it a gentle shake, and the colour change tells you whether indoles are present. It won't replace a full lab analysis, but it's the quickest way to check if what you've got is actually what you were told it is.
We've stocked these kits since the early days of the shop — they're one of the most-requested harm reduction tools we carry. A single phial costs less than a pint, and the peace of mind is worth considerably more.
Which Pack Size?
The EZ Test LSD and Indoles kit comes in three variants: a single phial for one-off testing, a 5-pack if you test semi-regularly, and a 10-pack for frequent use or sharing among a group. Each phial is good for one test — once the reagent reacts, it's spent. If you only need to check one batch, the single is fine. If you test throughout a season or buy from multiple sources, the 10-pack is the most practical option and works out cheaper per test.
| Variant | Phials | SKU | Best for |
|---|---|---|---|
| Single | 1 | SM0187 | One-off check |
| 5-Pack | 5 | SM0188 | Occasional testing |
| 10-Pack | 10 | SM0377 | Regular testing or group use |
Why Test Your LSD at All?
A reagent test for LSD is the simplest line of defence between you and an unknown substance. Blotter paper, microdots, and liquid drops all look the same regardless of what's actually on them. You can't taste the difference, you can't see it, and by the time you feel it, you're already committed for hours. That's the problem this kit solves — in about 3 minutes, before anything touches your tongue.
Here's the honest answer: most of the time, what people buy is what they think it is. But "most of the time" isn't "every time." Substances sold as LSD have turned out to contain nothing at all — or worse, compounds with a completely different risk profile. The EZ Test uses an Ehrlich-type reagent that reacts specifically with indole structures. LSD is an indole. Psilocybin is an indole. DMT is an indole. If the liquid turns purple, indoles are present. If nothing happens, whatever you've got isn't LSD.
One honest limitation you need to know: this test confirms the presence of indoles, not the absence of everything else. It will NOT react to certain dangerous adulterants like N-BoME compounds or DOB. A purple result means indoles are in there — it doesn't guarantee purity. For that level of certainty, you'd need a full lab service. But as a first-pass screen, this is the best tool under ten quid.
How the EZ Test LSD Reagent Works
The Ehrlich reagent reacts with indole alkaloids — a class of chemical compounds that includes LSD, psilocybin, psilocin, and DMT. When the reagent contacts an indole, the solution changes colour, typically shifting toward purple or violet within 1 to 5 minutes. No colour change means no detectable indoles in the sample.
Each sealed glass phial contains a pre-measured amount of reagent. You crack the top, add a small sample — a corner of a blotter tab or a tiny scraping is enough — reseal, and shake gently. That's it. No mixing, no measuring, no extra equipment. The reaction is visible to the naked eye. Compare your result against the colour chart included in the kit.
| Colour Result | Interpretation |
|---|---|
| Purple / Violet | Indoles detected (LSD, psilocybin, DMT, etc.) |
| No colour change | No indoles detected — substance is not LSD |
| Other colour | Possible reaction with non-indole compound — consult colour chart |
The reagent has a shelf life, so store unused phials in a cool, dark place. Direct sunlight and heat degrade the chemical over time and can cause unreliable results. We'd recommend keeping them in a drawer or cupboard — not rattling around in a festival bag for weeks on end.
How to Use the EZ Test LSD Kit
- Remove the sealed phial from its packaging. Check that the glass is intact and the reagent liquid inside is clear or pale yellow — if it's already dark, the reagent may have degraded.
- Carefully snap open the top of the phial. The glass is scored for a clean break, but handle with care — it's still glass.
- Add a very small sample of the substance you want to test. For blotter, a tiny corner (roughly 2mm) is enough. For liquid, a single drop. For powder or crystal, a pinhead-sized amount.
- Reseal the phial by pressing the cap back on, or cover the opening with your thumb (wearing a glove is sensible — the reagent is mildly acidic).
- Shake gently for 5 to 10 seconds and set the phial down on a white surface so you can clearly see any colour change.
- Wait 1 to 5 minutes. Compare the colour of the liquid to the included reference chart. Purple or violet indicates indoles are present.
- Dispose of the used phial safely. The reagent is a mild chemical — don't pour it down the sink. Wrap the phial in tissue, place it in a sealed bag, and bin it with household waste.
Testing LSD is a good start — but if you're checking multiple substances, the EZ Test Complete Drug Testing Kit covers a broader range of compounds in one package. For psilocybin-containing truffles and mushrooms, the same Ehrlich-type reaction applies, so this LSD test doubles as a basic indole screen. Pair it with the Marquis reagent test if you also want to screen MDMA or amphetamines.
Storage and Shelf Life
Reagent chemicals degrade over time, especially when exposed to heat, light, or moisture. Store your unused EZ Test phials in their original packaging, in a cool and dark location. A kitchen cupboard or bedside drawer works fine. Avoid leaving them in a car glovebox in summer — temperatures above 30°C accelerate degradation significantly. Properly stored, the phials remain reliable for about 12 months from manufacture. If the reagent inside has turned dark brown or black before you've added anything, it's past its best — bin it and grab a fresh one.
Frequently Asked Questions
Does the EZ Test LSD kit detect N-BoME compounds?
No. The Ehrlich reagent reacts with indole structures, and N-BoME compounds are not indoles. This is a known limitation of the test. If you suspect N-BoME contamination specifically, you'd need a Marquis or Mandelin reagent, or ideally a professional lab analysis.
Can I test gel tabs with this kit?
Gel tabs can sometimes cause false negatives or unreliable colour changes with Ehrlich-type reagents. The gel matrix can interfere with the reaction. For gel tabs, cut a very small piece and let it sit in the reagent for a full 10 minutes before reading the result. If still unclear, a second test or lab service is the safer bet.
How much of my substance do I need for one test?
Very little. A 2mm corner of a blotter tab, a single drop of liquid, or a pinhead-sized amount of powder is enough. Using more doesn't improve accuracy — it can actually make the colour harder to read.
Will this test tell me the dose or purity of my LSD?
No. The EZ Test LSD is a presumptive screening test. It tells you whether indole compounds are present or absent. It cannot measure concentration, purity, or dosage. Only quantitative lab analysis can provide that level of detail.
Can I reuse a phial for a second test?
No. Each phial contains a single-use amount of reagent. Once it's reacted with a sample, it's spent. That's why the 5-pack and 10-pack exist — if you test regularly, stock up.
What other substances does the Ehrlich reagent detect?
Any indole-containing compound will trigger a reaction. That includes psilocybin, psilocin, DMT, 5-MeO-DMT, and AMT, among others. The test confirms indole presence — not which specific indole it is.
Is the reagent liquid dangerous?
The Ehrlich reagent is mildly acidic. Avoid skin contact and don't ingest it. If you get it on your hands, wash with soap and water. Wearing gloves during testing is sensible but not strictly necessary for brief contact. Dispose of used phials wrapped in tissue inside a sealed bag.
How quickly do I get a result?
Typically within 1 to 5 minutes. Some samples react faster than others depending on concentration and form. If you see no colour change after 10 minutes, the substance likely contains no detectable indoles.
