Okay. went to the candy store and got the super concentrated stuff. Coffee and vanilla. Mixed 50 / 50 with my juice and i dont taste anything??
The coffee and vanilla flavorings are so dark almost black. That okay?
Hi redroush. Your story makes me raise one or two eyebrows
Many extracts and concentrates are NOT for vaping. Concentrates with oil may prove ill for your health, since the human lungs have no function to secrete the oil, once it's down there. The reason why you don't serve (pea)nuts to toddlers and small kids.
And - the mix you have, and the coloring, doesn't sound right....

Don't use it, imo.
To be fully safe, visit a website that have DYI-equipment on the list.
A list of supplier can be found
here. Five to fifteen percent of flavour in the mix should do it - depending on the flavour. It's easy to add somne more flavour - it's much more difficul to take it out

Vanilla and/or coffee are good "blenders" for almost everything.
Good luck.
