PPA isn't that hard to get - yeah, the FDA has pulled it, but youcan still order poundsof shit shit for pennies a gram from overseas sources... trying getting a workable amount of cyanogen bromide ..
As for why we don't see it more - it's not horribly complex to make, but if you have the setup to make Ice, then you could also make some REALLY GOOD METH... when the costs of the two are compared, and you factor in the work-load, the meth is more profitable...
Sales are another problem... we made Ice a total of two times, and it was a bitch to sell because NO ONE know what 4-MAR was ... we would try to explain, but it didn't matter.. we sold almost our full batch to one guy and explain EVERYTHING, even rpitned out documents... well, 3 days later I over-heard him selling it as "Ice, yeah, it's like refined meth" .. people just don't understand the chemistry behind their drugs ... from then on we stuck to meth, asthe profit margin was higher - still, for a club or party, 4-MAR is FAR BETTER IMO! Easily worth the extra 25% ..
