get some MDMA and some MDA and try them out and compare results. Use a simon's and mandalin test kit to be sure.
but be prepared for the come down, it can be quite brutal. I think the brown euros from a few years ago contained a solid dose of mda.
The Brown euro's? I didn't think they were all that great
The Brown euro's? I didn't think they were all that great, the white moons the previous year or the year before kicked the shit out of em. Never had crystal/powedered MDA though, but I've had MDA pills numerous times, and I must say, MDMA is still my favourite but splash some MDA in with the mix and the night is all rise baby allllll rise
