theres no vg or pg in it at all.....its all peg-200 and peg-400....which is what people vaped-harmlessly-before morons pointed out that these are components in some antifreeze...and you can't drink antifreeze......of course, you aren't drinking it.....
and i don't use bho, i don't like the thought of it, i was speaking more from a consistency viewpoint, but i'm sure you would have no problem getting bho to dissolve in the peg mix.
you can either use a hot water bath or just put your container in the microwave about 8 seconds, stir vigorously, if it does't all dissolve, give it about another 5 and stir till it does, it takes quite a long time to settle out, and just a good shake or two gets it mixed back up.
i'm thinking about getting an emulsion blender, pretty sure if you hit it with one of those fresh out of the microwave it would never seperate at all
the consistency of the peg is quite thin, but the concentrate you add to it thickens it up quite a bit. wax-liquidizer says 2 ml to a gram of concentrate, but i've found three works a little better, may not be quite as potent, but it also doesn't gum up my coil in a couple of days
