I know that it's verboten to discuss sources on this site. This question relates not to any particular source. It seems that powders are rather in vogue these days, although I have heard that customs are on the lookout for them. Buying poweder would seem to be a simple and economical way to go but my concerns are as follows. Number one, most come from China and China imports seem to be under the gun at present. Number two, the typical amounts, 10,000 mg or more, would have to be construed as dealer amounts. Number three, with all of our focus on terrorism, including white powders, i.e., anthrax, powders would seem to be a risky proposition all the way around. I was just wondering if anyone would care to express their opinions on this.
