Collection: Drinkcheck Wristband

Knockout drops are a growing problem. According to a US survey, 56% of women and 44% of men have experienced knockout drops.
It is estimated that GHB is used in 94% of cases
The knockout drop substance GHB (Liquid Ecstasy) is particularly dangerous. It cannot be seen, tasted or smelled. It takes effect after 15-20 minutes. For the victim, it feels as if they are "getting very drunk". A film tear lasting several hours is certain. The detectability is about 6 hours. Since GHB can NOT be recognised with the human senses, only a test can help.

Xantus is the world's first wristband with which you can easily and reliably test your drink for knockout drops. Several independent institutes and studies have scientifically confirmed its reliability. Patent pending.

Study results: 98.2% reliability

Lives already saved

Xantus has already been proven to have saved the lives of 21 women. The test has worked for them and saved them from drinking KO drops. The women have contacted us by email or social media, and we have had personal contact with all of them.

A tremendous success!

Every single one of them is important and we are delighted that we were able to help at the crucial moment.

Täter geschnappt

Two perpetrators have already been caught using the Xantus test!

The test was successful and the women were able to alert the police. Vials of GHB (KO drops) were found in the bags.

KO Tropfen in 94% ist es GHB

The substance GHB (liquid ecstasy) is used as a KO drop in an estimated 94% of cases, making it very popular and widespread.

Tasteless, colourless, odourless. Easy to dose. Inexpensive. The high dose comes very close to that of alcohol intoxication and matches the common description of the experience of KO drop victims.

Many substances are theoretically possible. However, almost all of them have properties that make them practically unsuitable. Some examples:

GBL has a strong, chemical, disgusting taste of its own.

Typical symptoms of ketamine are the "K-hole", melting into the ground, hallucinations and sometimes the feeling of "flying through the galaxy".

Since the 2000s, Rohypnol has had a bitter taste, turns the drink blue and leaves lumps. The symptoms are also soporific rather than "heavily intoxicating".

Water also turns blue

If it is pure water or rain, the test field will turn blue for safety reasons; the blue colouring of pure water and rain is a warning that the test field has been accidentally exposed to splashed water and cannot be used for another test. The test works normally with water based drinks such as juices, beer, wine etc.
