I have 5 bottles of premium strawberry milk that's pretty weak. (I know but it was on sale) I also have strawberry milk flavor from 2 different companies. I haven't tried either yet. My question is whether or not I can add the strawberry milk flavor to the premium bottles and if so how much? The bottles are all 60ml. If I have to I can vape them as is but I'd really like a stronger flavor. Thanks for any help or advice.
