The liquid nicotine alchem currently makes they have branded NicSelect, and the nicselect site is an informational site from alchem about there product and where vendors can order wholesale, not retail.
The nic has coa's of every batch and is extremelly pure, like e.g. chemnovatic and nudenicotine(going by there coa's) and one of the plants in india got inspected by the fda back in 2012 and declared as acceptable by them.
There have previously been reported strange tastes/smells like rubbery and such, but I believe that they have come over this issue now. That was reported to be related to the different kinds of
tobacco used, as opposed to e.g. just stems, and also what "stuff" the
tobacco draws up through the soil etc.
The nic is not as neutral like e.g. chemnovatic's(vapers tek/inawera/pink-mule and own-brand), but has a pleasant nic taste and smell i.e. woody/nutty/damp-
tobacco'y.
If you're interessted, then I quoted a reply about there quality from the vice-precident of alchem, back in the latter posts of the nicotine comparissons thread...
