alot of you who are into rc's have probably noticed some vendors offer the choice of chinese or eu stock. alot of people will say they are the same product since the company who has suppliers worldwide all share the same synthesis. i figured that made sense. but i have noticed ordering the same chemical, from the same supplier (highly reputable), but getting the chinese stock was a few dollars less, but seemed different to the eu stock of the same chemical. now they both were about the same thing, offering the same effect, and i couldnt tell any noticable difference in potency, however, they tasted completely different and even had slightly different textures to the powder. i am still unsure about this, and any experienced rc enthusiasts that would like to shed some light on this query, would be great.
