I second the olive oil and sunflower lecithin. My understanding is the lecithin is used in almost all pill rendering In pharmaceuticals. It makes the active ingredient uniform throughout the pill making process.
It also makes any cannabinoids uniform and homogenous throughout the oil. So that the dosage is uniform and you don’t get strong spots and weak spots. Aside from making it more bio available for the body by essentially emulsifying it into small equal droplets. It’s a must if you want to UP your game in oil extraction for edibles.
My long research concurred completely with MD buds that coconut oil and olive oil have the most carbons in their hydrocarbon chain. That directly makes more capacity in the 2 oils to hold onto more cannabinoid’s. Forget the butter; it has lower capacity and spoils too quickly.
I personally prefer the olive oil because it’s a liquid at room temp and has a longer shelf life without going rancid. And no one looks twice in a bottle of olive oil on the kitchen shelf. Coconut oil lasts a long time too but the solid state is much closer to room temp. And It can make it hard to work with for totally inexperienced users. If someone accidentally gets too high on their first time trying cannabis they usually never try it again. Especially people on the fence with trying it as medicine only (I share most of my harvest as finished olive oil and that has been my experience).
The example I have is a good mentor friend of mine had to go on a GI feeding port after surviving hacking out bad esophageal cancer. He was on a liquid diet and can only feed thru the GI stomach port. He liked to use my olive oil because he could shoot it right into his feeding port and it would not get clogged up like the coconut oil would.
Also, if you have people who really don’t want to feel intoxicated at all (left over prohibition guilt from the relentless brainwashing). The olive oil is super helpful because it can be easily cut with more fresh olive oil. I tell people if they complain that it made them feel loopy to cut it 50% with fresh olive oil. Then micro dose all day long. It’s really easy to do when using liquids versus solid-state coconut oil. The olive oil I can give somebody a plunger and say use 2 mL. That’s hard to do with the coconut oil. I am not hating on coconut oil, just loving the olive oil for it ease-of-use. I have used coconut oil plenty.
Sorry to cut in on your thread MDbuds. 
That’s just my five cents to add to the tab.
