How to tell of purity

[snafu]

^ Again.. not really true

If you send it into ED they just tell you WHAT is in it, not how much, or how pure it is. Unfortunately, there's no real way to check for purity in the American market. Only the Dutchies with their free test centers have that perk.

My mistake, dancesafe won't, but if you're in Switzerland, Streetwork will tell you, or testing facilities in the Netherlands. Or you could get your very own GC/MS machine, but that's out of the question for most people.
