I find that pretty hard to believe. I have had their ejuice a couple times, i won some on reddit when i was still there, when their company started. They sell concentrates for those liquids that i won, one of the was Fruit Hoops and it was made from common flavorings that i have on my shelf. This was long before they were doing anything in the DIY market.
Id be cautious in purchasing their stuff or relying on their CS for answer, as the DIY sub found out.
Thanks for the info @DrChud.
