Ask the vendor if you can get a different ratio of PG/VG. If not, then it should be ok right out of the bottle. Probably sat on shelf for a while before shipping.
I get some mixed to order. I leave them alone, other than a shake or two once a day, in a dark place a week or ten days. NO! NOT there!

That allows the PG/VG and flavor to "meld". It also allows the nicotine to permeate the liquid.
Boiling speeds the process of alcohol evaporation. Boil with caps loose. Or, just remove the cap and let it sit. Alcohol is a volatile chemical. It evaps pretty quick.
You CAN invest a lot of money into ultrasonic, heated devices but, WHY?
Here's a way to test you juice without investing in a dripper: Buy one EVOD (or any BCC tank that's got a replaceable coil head), unscrew the tank, drop about 3 or four drops of juice on the exposed wicks. Screw it back together and take two to three hits. That'll give you an idea of how your juice tastes. Don't push it past 3 hits. You COULD burn out the wick. And get an awfully nasty hit too!
Keep on Chuffin'
