back in the 60's, most of the acid came in pills. 250ug and 500ug standard. pharmaceutical shit. now, though, if you buy acid in a pill, you'll probably get various combined drugs that really are not LSD at all.
Yea, he's right... but you could get a pill of lsd nowadays but it's called a microdot. It's a pill so small that it sort of just looks like a really small circular cut out of a piece of paper... You can see pictures of microdots here: http://www.erowid.org/chemicals/mescaline/mescaline_info2.shtml That's an article written to show why mescaline doesn't come in microdots, I just posted it in another reply but now you get to see how big a pill of lsd is in modern times.
If it is prest in a pill form or in a gel-cap; it could be one of the many kinds of, Tryptamines (Psylocibin) or Phenethlamines (Mescaline) type Reasearch chemicals floting around. I hear/read; there has been in some cases, 5-meo-amt (A research chemical)placed onto blotters or onto sugar cubes and sold as LSD. Becarful! The taste is very bitter! There also is a new chemical floating around called "Bromo Bragonfly" the dose of this one is 100ug per hit, no dought this will be found in liquid form or on blotters etc... this one last a good 24 hours! and is very trippy! Dose s-low if it don't glow!
Yes, it called a microdot. http://www.erowid.org/chemicals/lsd/lsd_images.shtml EDIT: whoops, someone beat me to it.
I read somewhere that drfly can be active in even smaller doses than 100 ug's, but anywho I'll probably wait til a few more guinea pigs try it before I do... :H
