Not now - I used to for past batches and they held without fail while not having a reputation of causing much PIP, but with the current useage of less than ideal intermediates in the production of some AAS raws including Tren E & A affecting certain properties including their propensity to crash (it's that post you criticized me for when I mentioned long term raws storage), and having to ship them into the winter cold (not a concern for homebrewing obviously), I added 2% EO temporarily, though going up to somewhere around 25% BB should have the same effect. If I remember correctly, Colonial made his high concentration compounds including Tren Ace 200mg in MCT without adding extra solvents by raising the BB even higher than that, but someone check me on that.
