There is already a couple megathreads about 6-APB (benzo fury is a bullshit name), but they are really cluttered. 6-APB sounds like it has potential to be a good substance, but at this point the majority of what is being sold as 6-APB is not really 6-APB but a mixture of random RCs such as NRG-1. I would wait awhile until legitimate sources are established before attempting to order any. I have also heard that the Marquis test will come up as purple/black if your 6-APB is real.
