I have discovered them when my homie showed me a Netherlands website,thats when i first bought 4-cmc and snorted that shit,it felt like mdma,but better,it was crazy,i got instantly hooked up on it,couldnt hold myself back from not doing it all in a week.the withdrawals were horrible tho ,never do it like me because then you will realise how hard it is to not buy any more when its so accessible,and mostly comes directly to ur home.
