Well you didnt give me nearly enough info to help you, so i'll hit it from all angles...
If you buy it in a club, chances are it's cut to hell and back....and you can suck that whole 20 up, and it'd be like 10$ worth the Kata, if not less...dont buy from a club...end of story
Now overseas on the other hand, snag some USP grade, shit's 99.8 percent pure, so it's cheaper *alot* cheaper, more pure, and all around better than bottles, other than the fact that u dont get a science project, and you dont get to scrape the paste and watch it slowly form into what we know nad love as Ketamine Hcl...but hey...
And on a final note, Bottles arent powder, they are more expensive, but you get the neat little box and your science expiriment, for a mark upped price of anywhere between 70 - 100 bucks....
Have fun.
and dont buy from clubs.
