Easily MDMA, before I completely played it out and it lost it's magic. Still the best drug I have encountered when it was good. (And btw, it was good for YEARS before it stopped being fun)
A close second was my first Mephedrone experience. Shortlived, but amazing nonetheless. Waves of euphoric rushes.
Surely has 2 be Crystal MDMA .
Alot cleaner than most uppers / stimulants .
Did some about a year ago, lovely not to intense . I usually can't stand uppers apart from the odd pipe tis is due to doing loads as a kid and feeling those nasty comedowns .
But i will always make an exeption 4 some pure MDMA i have IVed it and that was unreal .
Also i ve mixed it with a bit of H and IVed that wicked combo.
Almost forgot H and cyclazine that was a long time ago don't see that about at all round here now
oxycodone puts me in a land of beauty. something about sitting in the woods playing my guitar increses my euphoria.
