Appeared on the UK scene only this week. No real info as yet beyond the merest handful of anecdotal reports from those lucky enough to have had a sample previously from the vendor when they were looking at bringing it in. Shorter acting version of 5-APB, maybe about half as long for peak, some say more straightforwardly stimmy, some say has similar psychedelic effects to 5-APB, seen a comparison to methylone though not as cathinoney in feel, either way similar euphoria and entactogenic properties, all very vague. More than that very little, as you'd expect at this point. Some interest in it, will see how it compares but expensive at the minutes, silly expensive, will wait for prices to fall as more comes available.
