now in my third decade of searching, theres no doubt
i have the biggest dick in melbourne 
... but i reakon there be a fair few prepared to step up to the challenge.
i havnt had 5-meo-dpt, or 2ct7 ( i think... unless unknowingly, very doubtfull.)
nobodies mentionned anything else ive not tried, except some pharmaceuticals that i may or may not have stolen from nanna's bathroom vanity draws in my teens. back then we used to inhale "no stick", it was like "pure and simple" only it sent you right off. that was '79...and now 20+ years later im still interested. i gave up acid about 5 years ago, and believe it to have been after about 350 tabs, and 100 drops(guestimate)... but thats just being conservative... and not something i do any bragging of.
not only have i given most stuff a go... i punished it hard (for example last year alone i ate over 150 mdma based pills!! and then some other recreationals.) and dont you dare flame me... im a successfull professional. retired estate agent. work for two well known community welfare organiseations, secretary for a stategic gaming society called GSIS......
anyways so after a thousand or more recreational drug experiences- ive still got it together... in the most part i'd say. yet some people will fall apart after 1. who knows how it affect your friends, i know ive lead the wrong people down this path on occassion, and believe me its no fun when your friends get all fucked up, or stuck into smack, or die. its hard to imagine, but ive always felt like superman... nothing gunna harm me.
