it's because it's citric acid was used and is why cheap, easy to get, food grade citric acid isnt used. i think it is also heavier then the hcl salt, and because theres not a great deal of info on mescalin citrate, it will be hard to dose. then again, sometimes thats half the fun ya? hahaha
citric acid is actually not any safer/more dangerous then hlc acid when ingested in such small amounts. i mean, your stomach is full of hlc acid, and that is assuming you didnt clean your final product up. hlc salt is a whole lot easier to clean the exess hlc acid out of it seems, because from experience, acetone seems to disolve citric acid. that sucks...
