Please note, there is a difference in these flavors and in Lorann type oil concentrates.  This IS NOT as powerful as the oils.  The reason for this is they are not a thick lorann's oil based.  They are the waterish  based flavor concentrates that our factories use to produce the flavors we normally get in our eliquids.  This means that unlike lorann's you'll need more than a drop or two for your flavoring when mixing yourself.
