Has anyone injected lube into the bladder?

Title says it all I’ve seen a few videos and it looks satisfying

I am always careful about what I put into my bladder. I have yet to actually inject lube into my bladder but I will say that lube probably has made it into my bladder from inserting other things. It probably won't be bad for you anymore that other things just make sure that the lube you are using is safe for internal use.

Gives "ball bearing grease" a complety new meaning

I will say that when I inserted ball bearings into my bladder I didn't use lube on them because it would make it very difficult to get them in. However when I use sounds or a vibrator I used some to make it slide in easily and perhaps some made it all the way into the bladder but not any large amount.
