Content: 24 mlIsopentyl Nitrite - CAS 110-46-3What on earth could be even better than Amsterdam? Amsterdam Black Label! Black Label reminds one of Amsterdam Poppers, with which it indeed shares some similarities, apart from the name, of course. However, the differences between the two are much more striking. Amsterdam Black Label is infinitely more potent, having a stronger and longer-lasting effect than most (if not all) other poppers. And, let’s not beat around the bush: stronger + longer-lasting = better! By the way: Amsterdam Black Label not only works great, it even smells alright!
