Among them, the security of CS is much better than CN, and the irritability is more intense, and Oc, pherom is pure natural, non-toxic preparation, so they are widely used as the preferred stimulant. Sometimes two stimulants are used in combination, as some research institutions have considered that the composite stimulant has integrated several stimulants and better safety.

Solvent requirements

are mainly used to dissolve the stimulants and other components, and the carrier used as the stimulator injection.
