Actually I thought it was like 10cc's of air to kill.
BUT Ive seen plunty of time where people have injected a vien and lived.. but its not recomended. Ive seen studies from the 60s and 70 where small amounts where given direct to viens. If memory serves the problem wasnt enough binding going on in the blood so even long esters were filterd out before it could be used.
For one oil does not mix with water!! I think you should hypothetically try it and tell us about it. lol
I would say using suspension would fix this... but i cant imagine the particals would be fun swiming in your viens... if anything i would see if you can get acetate. In very small doses. Quick ester and pretty thin oil too. May avoid the clumping... ya no.. hypthetically.
