My testosterone propionate does something wierd too, it came out perfect but after it sat for 2 days, it had some crystals on the bottom, not too many though. My bro told me to give it a hot bath and then draw it up once the crystals dissapated, but they never fully went away. My bro said this was fine and not much is lost at all. My next bottle was cloudy so I do the same thing, give it a hot water bath before every shot, so far so good!
