LSD Identification Guide

This guide is intended to be used in situations where a Test Kit is not available.

Please arm yourself with these powerful tools to insure the maximum safety and legitimacy possible, there is much more information about our kits at the bottom of the page.

Crystalline LSD is invisible to the naked eye unless you are dealing with hundreds or thousands of doses. It also lacks a smell and taste unless it is very concentrated. As you might imagine, these characteristics make it very difficult to identify.

LSD Hoffman Blotter

 LSD Blotter

Taste: Legitimate LSD blotter will be tasteless in the vast majority of cases. It is possible for there to be enough LSD on a blotter to taste slightly metallic or bitter, however this is extremely unlikely. Therefore, if it tastes bitter, fruity, or like anything at all, there is a good chance that the active substance is not LSD.

*A common opinion is that the ink on blotter is what makes it taste bitter. This is technically possible, but rare. DO- and -NBOMe chemicals also taste bitter… so why would you chance it if it ‘s LSD you’re trying to identify?

“If it’s bitter, it’s a spitter”

Size: A normal size LSD blotter is around 1/4 inch square and and 3-5 times the thickness of a dollar bill. This will hold an active dose of LSD, but an active dose of most other substances will not fit. Many of these substances will come on wider and thicker blotter paper and even sponge in some cases.

DOB LSD Blotter

Too large and too thick: DOB blotter

“If it’s larger than 1/4 inch square, beware”

Liquid LSD

Taste: Again, LSD is tasteless unless it is highly concentrated. Liquid LSD is usually a mixture of the crystalline substance and either distilled water or alcohol, which both lack a bitter flavor. If your sample has a taste, especially a bitter one, it may indicate the presence of another substance.

Color: Properly refined LSD is colorless and so are distilled water and alcohol. If the liquid sample has a color to it, this is an indication that it may be something other than LSD or that the LSD used was quite unrefined.

Viscosity: A mixture of LSD and distilled water or alcohol is relatively thin. If the sample is thick or syrupy, this is an indication that it has a large amount of another substance dissolved into the liquid. It is very unlikely that this substance would be LSD due to the very low dose required.

Other forms

LSD comes in a variety of other forms, such as geltabs, microdots and sugar cubes.

Types of LSD

Geltab – Microdot – Sugar Cube

These forms of LSD, due to their size, could be made up of any number of substances.

They are very difficult to identify without further testing.

To Be SURE Test it

LSD Test Kit

When using this kit, the sample will turn a bright pink in around 5 seconds if it contains LSD.
