BB or castor, which solves more?

Of course hormones :) The sense of this question is that I must balance between my mixture of the carrier.
Think of it this way, BB increases the solubility of the oil.

At the same time however, there is a point where the oil can no longer dissolve any more BB you know. Im not sure what ratio this happens at with castor oil - may be very high Im not sure.
you alos have to think that some people have a bad reaction to castor
oil. its use back in the day was for anti toxins to fluse out the body
so if injected it will sever the same purpose.

i have not used or seen it in sometime but is it not a very think oil as well
