I just had a longer private conversation with Liska, he answered all my questions diligently, based on that I'd say he is a fine feline fella!
Given I am not a reputable, long term member of this site, nor would I be a high volume customer, that is very appreciated!
Regarding to my suggestion to list the ingredients for all your merchandise on the website and vial itself:
IMHO, if this would catch on, the amount of harm reduction across the sport would be very high as this would make people more aware what they put into their body, if they knew what solvent and the actual amount for some of the compounds, they would probably think twice.
Accountability for sources would increase if it came out that they put in more, or worse more toxic, solvents into the finished oil.
I'd rather take underdosed gear than not knowing that I am taking guaiacol, or at least not knowing how toxic it is.
