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

A huge success!

Each and every one of them is important and we are delighted to have been able to help at a crucial time.

Two perpetrators have already been caught using the Xantus test.

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

Several independent institutes and studies have scientifically proven the reliability of the test several times, with a reliability of 98.2% according to the study

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".

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.
