So i go to get my bottle for my weekly dose and when i go to pick it up it was on its side. Not a big deal but what surprised me was this dark spot on the side/bottom of the bottle. I thought it was on the outside but it wasnt. Its like this black residue had settled on the side/bottom and when i moved it, it would kinda float around till you really couldnt see anymore then seperate and go to botttom. If anyone has any info on this please let me know. Thanks
