as in these << ones on my avatar?
I had tabs from a few different sheets of these and they were all medicore/good/great.. so if they are the old ones they should be OK

however you never know, they could be a new batch, so take one first to stay safe..
i am very interested in these Hofmann originals, sure hope they make it to manchester.. although 250mcg sounds a bit too high... im no acid expert; the first time I tried it was in 2006, but from what I have read 250mcg on a single blotter seems extremly unlikely.. one bit of net evidence is the
Erowid LSD blotter index with lab analysis of tabs from the 70's and 80's (when they were supposed to be stronger?) and NONE of them are over 100mcg per tab ??
please correct me as I could be getting something very wrong
