I agree with @cyclopath. MCT, in my research and experience, is the best carrier oil. It allows the greatest bioavailability of any oils that I have come across. Some research argues that LMCT provides more benefits, but it was only one study that I came across which said that. I have seen Grapeseed oil used as well. While sunflower lecithin will seep up intake, it is not required to bring the crude or distillate into solution.
Technically, you could add a single drop of carrier oil and that would provide you with maximum saturation. It will be highly viscous and difficult to work with, but the maximum potency of the oil is only limited by the potency of your crude or distillate. I have made oil as high as 400mg/mL, but that was for high dose, terminally ill patients. Why it would need to be that high for the general public is beyond my comprehension.
Please make sure to use decarbed product as well.
