i havent taken any...i dont think im going to either...
but some friends told me they were tripping for 10 hrs...which made me think it might be the real deal and not some other shitty chemical sold as acid...
as for it being weak i dont have a clue....you grow "immune" (cant think of the right word) to it extremly quickly so they may have started on half tabs then the next night done more...slowing building a resistance....maybe it is weak!....lol
but if you do decide to do any will you let me know what it was like..and i may have to try it if you make it sound good

And the tabs they have been getting are £5 a tab....which also made me dubious...my best mate sold this guy a 20 and he gave my mate a tab...just for nothing...
