irech77,
If you add 8.75ml's of 100mg Nic base to your 120ml bottle of 12mg Bubbas, you will end up with 128.75ml's of 18mg BubbasPer the ejuice me up Calculator
I suggest you download the ejuice me up calc,,,,, there is a tool bar on the top left which allows you to combine Nic strengths to calculate a final MG of Nic
WOW good to see ya Matt been awhile
Cheri are you sure its a 120ml bottle because if it the big green bottle from alien visions those are 100ml bottles FYI and I second the ejuice me up calc
