I recommend doing some math on nic level, dilution, and $/mg before diving in with the MBV nic juice. They are really marketing to someone who wants to buy premixed juice at the nic level desired for the purpose of adding a little pure flavor concentrate. Sounds like you want to do the opposite; add a little nicotine to premixed and flavored juice. Compare with a true DIY vendor and you'll find you can get a lot more nic/$ and at a higher concentration so as not to dilute your flavor as much. You can also buy a $15 bottle (60ml of 100mg) that will probably last a lifetime doing what you're describing rather than the MBV bottle for $37 (236ml of 36mg) that will last a little longer. But do you need a bottle that lasts longer than a lifetime?
Just food for thought. I may be off the mark as to what your wishes are.
