- Male adults volunteers (18-45 years old).
- Clinical history and physical examination demonstrating no organic or psychiatric disorders.
- The ECG and general blood and urine laboratory tests performed before the study should be within normal ranges. Minor or occasional changes from normal ranges are accepted if, in the investigator's opinion, considering the current state of the art, they are not clinically significant, are not life-threatening for the subjects and do not interfere with the product assessment. These changes and their non-relevance will be justified in writing specifically.

- Subjects with intolerance or serious adverse reactions to drugs or amphetamines, ecstasy and hallucinogen derivate, mephedrone or other cathinone.
- History or clinical evidence of gastrointestinal, liver, renal or other disorders which may lead to suspecting a disorder in drug absorption, distribution, metabolism or excretion, or that suggest gastrointestinal irritation due to drugs.
- Subjects unable to understand the nature, consequences of the study and the procedures requested to be followed.
- Subjects with positive serology to Hepatitis B, C or HIV.
