sounds like its trying to come out of suspension. next you'll see small crystals.
Since I personally can't stand BB add Ethyl Oleate to it. If its only 20ml. only add 30% to it. It will help with the pain factor also.
it is really not supposed to be like that at all? it is in a amber vial and i havent actually sucked it out of the bottle to look at it. could it be the bottle? or is there something seriously wrong
You could try heating it up if its crashing , boiling water in a plastis tub and sit it in for awhile then swirl it , or as Big T said try adding some EO (lurv that stuff)its at research sites very cheap .
It will be more than likely painful if injected while crystalized but prolly no bunk .
