Shambles

You won't be buying uncut amphetamine cos nobody sells it cos it's unstable and unsafe. It evaporates extremely rapidly and is caustic as fuck. Not safe to handle. You will find loads of shitey "base" paste that the dealer will swear blind is "pure". Smell and taste will be awful (cat piss is the usual comparison - should make yer eyes water even through a baggie) but is the same for even the worst quality speed. Only way to be sure (other than labtesting it) is to sample it. Or get somebody who is more familiar with speed to sample it. It should be insanely strong if it's even vaguely decent. A gramme should keep one person awake for a week or so. If not it's nowhere near pure but that's not to say it's not decent cos very few people would go near high-quality speed. I used to sell extremely pure speed and was frankly a pain in the arse. Almost all punters are so used to weak shit that they wouldn't buy it unless I cut the shit outta it for 'em 
(obviously this was many (many) years ago - i've not bothered with speed in the last 10-15years cos the quality is uniformly appalling imo, ime, etc,etc)
