Yes, I have added more BA to crashed stuff to get it back into suspension, but, a 10ml bottle of juice only has roughly .3ml of BA in it to begin with. If you added 1ml more of BA, even to a full 10ml bottle, thats gonna be some painfull shit (remember, it is the BA in test prop that does all the hurting), although it probably would hold suspension very well.
you know what helped for me, when i would bake it i would leave an 18 gauge pin in the stopper and that would let some of the BA evaporate during heating. i hated having to reheat the crashed gear every week, the added BA was a good solution and the pain was no different really. it was painful before so whats alittle more at that point.
