Hi, azhad is a well known italian brand and i'm pretty sure no harmful stuff is in their eliquids. I'm italian and i never heard(well, it should be "read" as i'm talking about italian vaping forums) of dyketones and stuff about azhad.
Also their liquids are tpd compliant so they should be safe from known harmful elements such as diketones.
I'm not a big fan of straight tobacco juices but i love the caribbean(tobacco with pineapple and coconut)
Ps:if you like tobacco eliquids and you have access to italian eliquids, probably you should check out the brand la tabaccheria.
