Honestly, there is something different in the bottle that I got. I've been vaping bobas for a long time, and never ran completely out of it. I've cleaned all my atties and tried a host of different devices, something is definitely different. Still tastes yummy, but it's slightly off. Even dig out some new old stock LR boge atties and the old roughstack to give it a try. Every week it seems to tone down, I guess BB may just need to steep now.
Have you tried Gamel or have any around?
