Sure this seems like it would work- but it just seems impractical to me. The solubility of a steroid molecule in oil is markedly diminished when you remove BA-and there is no way of knowing (in practical situation) how much BA is removed, and how much of the steroid has precipitated. The solubility is affected by temperature, so it'd still be an unknown even if we had a ball park figure how much BA is removed when you combine X solution with Y oil, and shake for Z time. To me, simply mixing with another type of gear seems adequate. Also, buying T400 if you're going to "water it down" makes no sense to me at all; why not just buy some t200 or primoteston instead and avoid the hassle? Just my opinions.....
