BB's affect on Half life

[zmurphy]

Any guesses on how the concentration of benzyl benzoate affects the half life of AAS? I would assume the more BB the shorter the effective half life as it thins out the oil, but I'm not sure. TestU half life is listed as 20.9 days in tea oil and 33 days in castor. Nebido is TestU in castor oil with 50% BB and Bayer itself says the half life is 53 days which is almost twice as long. Pharma TestE can be had from basically 0% to over 30% BB. With it being such a large portion of the total injection volume there has to be SOME effect one way or the other.
