So, I just got out of prison for a manufacturing charge in March of this year, went in April 2016. One pot condensed ammonia via pseudo, the two batches tested in my case came back 94 and 95 quality on the gc/ms... Obviously, it doesn't get much more pure than that.
Not tooting my own horn, it was a stupid fucking thing that cost me a big chunk of life, but I share that to say this: I dabbled a bit (read: relapsed) a couple months after I came home, and the potency and duration were among the most intense I'd ever had. What's more, the price was so cheap, I honestly can't see how ANYONE made money selling it...
But it wasn't the same. The shit was so caustic, so utterly destructive to every system from the moment of introduction to the body, it was impossible to sustain. Side effects presented almost immediately after the rush subsided, to the point that nothing about the experience was enjoyable, which of course did nothing to negate the compulsion to redose. After twelve hours I felt/looked like a hospice patient, after 24 I was praying for death like one, too.
The old stuff wasn't like that. I could bust a gram down 10 ways and make sure no one blinked til the sun came up, or slam the whole thing myself, wig out for half an hour, then embark on a twelve day journey (redosing, of course) before eventually crashing. Not safe, smart, or in hindsight particularly even enjoyed, but the point is the potency was there without anywhere near the rapidly presenting toxicity you get with today's shit. Add to that it's a crap shoot from crystal to crystal, one might send you to the psych ward, one might be totally bunk, and one might send you to the grave thanks to the fent that had no business in there in the first place...
Yeah, I'm good. I'm no better than anyone else and I still enjoy the occasional escapade, but not when the price of admission is poisoning myself and being aware of it the entire time.
Stay safe, or a much as possible out there, y'all.
