Salvia only lasts like 10 minutes, and it depends on the strength of the extract. I work with glassworkers and botanists, whom can get me 60X strength. I can get you some of that, but that shit s CRAZY insaneo strength. they shit at most head shops is the 12X stregth. ussually thats the expensive, they sell the lower 4 to 8X, to most people, and the 12X you have to ask for. No one carries the crazy 60 shit like i tried before. you will more than liely vomit.
