Containing MPA as an active ingredient, Synthacaine is a stimulant known to trigger bouts of euphoria, and is sold here in its pure form (98%). The purity of Synthacaine is key to its effectiveness in research, with the unadulterated powder being a legal substitute for cocaine. As such, it is useful for comparable research into the effects of that controlled substance on the dopamine receptors. Synthacaine is strictly for in vitro application only, and is sold by VohLabs for the purposes of research alone.
