PMMA in the glans is a no go. No reputable Dr. would inject
PMMA in the glans, too vascular.

HA is a waste in the glans, unfortunately. As others have stated, it doesn't last long. And you probably will barely be able to tell it's there, unless you inject alot of it, which would be very pricey for something that likely lasts months, not years.
I had 2 syringes in the glans in May 2024 and barely noticed anything, then another 4 syringes in September 2024, figuring I should surely see some results. Barely perceptible, for sure not worth it. I want it to be worth it, I really do (just like all of you I'm sure) but it's just not in my opinion. On the plus side it wasn't any more painful than shaft treatments and there's no aesthetic issues.
