maybe I'm unclear on what you are trying to describe... first things first, you should get your post count up over 5 and ask again in the diy juice forum.
but meanwhile here's what I think is going on....
you have several bottles of e-juice that are 32mg nicotine, 100%vg, and double the flavor -- right so far?
you say the product is "harsh" and yet "flavorless" at the same time? This is the part where I got lost.
If you mix what you have 50/50 with plain PG you will get 16mg nicotine, 50%pg+50%vg, and half as strong tasting.
I guess I'm wondering why you describe it as "harsh" and "flavorless" (especially since you say it's double the flavor) at the same time.
