Flualprazolam powder is a white, crystalline solid that is soluble in water. It is a derivative of Alprazolam, which is a commonly prescribed anti-anxiety medication. Flualprazolam powder is considered to be much more potent than Alprazolam, and it has a shorter duration of action. This means that the effects of Flualprazolam powder can be felt more quickly and will last for a shorter period of time.
