Thanks for the information. I intend to use them for mixes that I make but I feel need a little more flavor. That way I can add a drop or two without effecting the overall nic mg. I think I’ll make a tiny bottle of each just to get an idea of their taste but I mainly got them for an add-in flavor boost. I thought more people would have tried these but I guess it makes sense being priced so high. Kind of hard to try them when the smallest bottle is $20+, and you have no idea if it’s good. Well I’ll report back with what I learn from them.I tried a few of them a couple years back and they are really strong. I would start at way less than 1% for almost all them. Most probably 3-4 drops per 10ml. I will say this and its just my opinion, they are hard to work with because of the concentration and they take some time to steep. The same flavors can be had under the name "lotus flower" at ECX.
