Purity - Aquire LSD reagent test?

[SpaceKitten]

Posted this at another forum but didnt get any real answers that helped my friend so i hope someone here can help SWIM


A friend of mine has a few diffrent kind of blotters that he wants to make sure for 100% is LSD,
I know posting/asking sources URL's is understandable a no no ,so ihope
im not crossing a line here.
swim know of Erlich's reagent test and have googled for vendors, found one really expensive UK one ,one cheap UK,though he was unable to confirm if it was possible to order as a private person, and a couple of cheaper US ones, Only one mentions selling to law enforcements only and not shipping internationally
The cheaper UK one was for about xxx pounds for 10 test, but swim isnt sure about the safety of ordering from this site.
He is for obvious reasons a bit concerned about ordering such an item, and any help on aquiring such a test at reasonable price, safe and preferable within the EU,
swim knows of blacklight test too, and has access to both DOM and DOC and maybe DOI so i guess he'll be able to compare if theres any glow/ diffence as soon he gets a blacklight.
but help on gettting proper test would be much apprecieted.

Would URL's for sites selling these kinds of test but not any legal entheogens/rc's etc be against the rules ? since its about harm-reduction?
