I've got some N-CAT and M-Butylone on order for either tomorrow or Monday, so I'll give some feedback on both. Further to other posts I have a sneaking suspicion that N-CAT might be the same compound as NRG-2, but that's OK because I don't mind NRG-2. It's fresh in my mind, having done a little last week so I'd be able to report any similarity. I do wish they'd tell us what it is though. I'd feel a proper buffoon telling the St John's Ambulance man I have no idea what I just ate.
Had some MDAT last week, which proceeded to make me feel sick and do my biggest, most urgent shit of the century so far. Not recommended (unless you like doing massive unexpected shits, of course).
