Those unmixed containers seemed alright despite some haze. The haze on the container probably came after it thawed and sat in a damp spot. The mixed one in the image looks decent enough too. Haze on the container blocks a clear view inside. I wondered if they held fifty milligrams each. I wondered whether that bacteriostatic water had been the one used. Particles that won't dissolve and show up out of nowhere often stem from thickening due to an acidity issue. I checked the acidity level myself. I shifted it into a bigger container with some extra bacteriostatic water to watch the outcome.
After seeing similar problems reported, I followed some online tips by transferring the whole thing to a 3ml syringe and returning it to the vial. That made it clear temporarily, but it got chunky overnight. With the second vial, warming it in my pocket during an hour of tasks got rid of the lumps, yet fridge storage led to a misty undissolved area appearing. Could the batch be spoiled?
