its from london, hopefully it is that strength, shall report back once tested
Plenty of liquid in London - not all from the same source by all accounts, but accounts could be wrong. All standard strength (100 ug /drop ) and clean from what I've been told or experienced myself.
I wouldn't personally be confident about differentiating 100ug from 120ug myself, but it's certainly all in that ballpark.
Beware Bromo-Dragonfly blotters that are about. I'll explain in further detail soon.
None of the popular prints though.
Is it not soon enough for that further detail yet SG?
