Hi Greg,

Its hard to say how many drops this would be as there are different size droppers on the market. But the general rule of thumb is the use of Terpenes to flavour e-liquids is usually 1% – 5% of terpenes max to be added to the vape liquid.

For example: At the lowest suggested level of 1% content for example you would add 1ml of Terpenes to approx 99ml of other liquid, so the 2ml bottle you would add to 198ml. At the highest suggested level of 5% you would add a 10ml of Terpenes to 190ml of liquid.

Hope this helps 😉
Regards Jess.
