they not tell the real name of the chem so it cant be banned so fast...thats the thinking behind ..... and for moment works...probably the vendor it self dont know which compound is ku in reality....and probably change drasticaly from batch to batch.....thats the new strategy of rcs producer.....sad that they didnt thaught to it before, when good rcs were still unbanned..... Now they found a valid strategy but the best synths are gone.
ps tried only ecu... bu.... apip .... md pep and new a pvp analogand yes there are some activ ones but for me as smoker the taste is horrible....... but i love the taste of hexen and nep....... a phip is unsmokabel too by my opinion its so sweat
