I've ordered lots of MDMA in the past, but never MDA. Wanted to try this so I ordered 1 gram from goingpostal on AlphaBay.
In short, what I got was: great stealth, and top quality MDA.
I had the MDA lab tested (as I always do with all drugs I use or share). This came out at 83% which is the maximum possible purity for MDA. So this is absolutely top quality stuff and definitely deserves a 5/5 rating.
Didn't use the MDA just yet, so I'm curious to find out (and also if there's a big difference with MDMA).
You're in for a treat. I have some karmasyndicate mda which is great stuff. Read up on dosage though, you use less than mdma.
