yea, whatever you do dont mix a 100 ml bottle if it turns out nasty then you trashed it all. also remember adding anything to a 12mg base will bring the nic level down some more.
wizlabs is the best place for nic
Make sure you download the ejuiceme up calculator, its free and once you understand it works perfect.
i get labwear (vials syringes and stuff) from wiz.
the flavor apprentice and lorrains oils is where most of the wiz flavors come from
when i order flav's from TFA i usually also order pg and vg.
the best thing to do is get a small bottle of 100mg. mix it down real quick using ejuice me up to about 36mg and then you always have ready base to whip something up.
I know it seems tedious, but mixing small bottles until you find recipes you like is the best way, i dont know how many 10 ml bottles hit the sink in the past and so glad it was a small amount.
if you are interested in DIY you should check out the DIY forums. lots of tips, tricks and recipes ...........
in the end when you start finding recipes you like it gets dirt cheap, i can mix my Double caramel candy ry4 for like 1.20- 1.60 a 50 ml bottle
