I have two bottles of Stan QV 100 both look legit(stickers, holograms, snap top exact same on both) the only thing is one takes a lot longer to settle then the other. They both mix with no clumps and settle fine. One just takes a lot longer. It seems like it has more powder in it. Both bought at the same time and at the same place. I should have payed a little more attention. We are planning on doing best 2 out of 3 paper, rock, scissors to see who ends up the longer settling winny lol. Just wanted to get some opinions and experiences if any. Batch numbers match the Qv site and each other. Gotta love Mexico.
