@jigsaw - like I am saying below here: Marquis reagent is a type you can use and it is probably identical or similar to EZ test. Good idea by allium indeed. Other than that you can get things tested in the Netherlands or Spain (Energy Control), and MAPS may also do it for a hefty fee.
Other than this we cannot help you.
@rouss Scoff at it all you want, still we cannot pretend that we as a community can tell you what drug your unidentified blotter or powder is. What we can do is suggest ways to get actual info or suggested info on it for instance by using something like a Marquis reagent or other color indicator agent. Is that what you were asking about?
Yes we have a set of rules and we follow them. Other than that feel free to ask your questions. But we can't help it if you want to get something from BL that is not in the best interest of Harm Reduction.
Suppose we would allow people to suggest to others that what they have is indeed magic mushrooms, but actually they are poisonous. That would give a person a false sense of security, which is WORSE than not getting a conclusive evidence about your unidentified drug.
As long as you don't have enough ID information about it, you shouldn't take it and if you cannot get methods to identify for yourself you may even want to throw it away. Yes! That's better than taking something without knowing exactly what it is, unless you like russian roulette a whole lot. Sorry that we cannot reach through our screens and help you more adequately but you cannot expect to have PD/BL fix your issue magically.
On the shroomery there are experienced mycologists who, in the case of mushrooms, might be trusted to ID by photograph.
