TPA DRY4 needs a full four weeks of steep time imo. I usually mix at 10 percent for stand alone or 8 percent when mixing in other flavors. Mixed at about 5 percent I can vape a little of it fresh but not much.
My latest bottle was evidently from a bad batch. It's clear as water, doesn't have much smell, and tastes very weak. It doesn't sound like you have a bad batch, because at least you're smelling something, but you might want to read this thread, just in case you haven't seen it. http://www.e-cigarette-forum.com/fo...nging-weak-sauce-what-gives.html#post13939221
