What UI is this?

[Panzero]

Does anybody know from what UI does this health bar comes? Been searching for hours but nothing.

No idea, but if it's not from one of the popular UIs here (Duxa, Vert, etc.) your best bet might be to wade through all the UIs on https://eqinterface.com/. The site is for live EQ, but some of the custom UIs work on P99, and whatever UI that screenshot is from is likely on there.
