To redissolve crashed aas, you must warm the aas to the point that it will redissolve.... To do so with the label intact, you will want to use a 'dry' method(meaning putting it in a mug of water that was brought to a boil is not the way to go... That's the easiest way to do it). You can put it in an oven, with a vent needle in the stopper(of course, this means you must break the seal on the cap.... ), you will want to warm it slowly, with the oven at 200-250 degrees. it will take 30+ minutes to get the oil in the bottle to temp... at this point, you will want to shake the bottle for a couple minutes at a time(using a pot holder or towel to handle the bottle, it will be hot)... put back in the oven and repeat this process til the aas is completely clear, with no crystals at all(this can take quite a while.... depending on the potency of the aas, and how bad it is crashed).... Your best bet is to call your buddy, and have him look at the bottle, so he sees that it is what it is supposed to be, then boil a mug of water, and drop the bottle gently into the mug of water, let sit 10 min, shake, repeat.. till it is fully dissolved again... this method is much quicker than the oven and does not require 'venting' the vial.... This may make the label come off, but as long as you let your buddy inspect it, and see what you are doing with it, he shouldn't have a problem with still taking the bottle....
good luck
