got sent a gram as a free sample (real I am, don't know- a product of bdeing so 'notorious'!) from someone I know who is a vendor. Seems OK, well for old man type focus only, but has that capacity that it will not stop. Beer, benzos - it takes a fair bit to stop the analytical part of the brain to stop looking for patterns in EVERYTHING around you. It basically feels like long lasting, watered down MDPV (pornograph tendancies included in this). Don't think I'd actually ask for some if/when this gram is gone (it will, most probably - a sad indictment!) and I thought I was done with that. Tried ethylphenidate and that was OK, but the levoacetoperane (reverse ester of methylphenidate) is one I'd be willing to give a go (again); it has marginally better binding figures than methylphenidate and it appears people like methylphenidate, so it seems a natural candidate. Who knows, someone, somewhere may well be beavering away... (yes I've tried it and it was fun, but that was twenty odd years ago and like I've said, the subjective feel of stimulants has changed for me with age/(overuse))
