Agreed, and ALT falling is not the same as fibrosis improving. Enzymes are a crude proxy; FIB-4 or elastography is what tells you about the thing that matters.

Adding a me-too, because a thread of one person's experience is not much use.

Coming at julia.endo’s question from a different direction. The liver data is among the strongest non-weight findings in the class. The semaglutide MASH programme reported a large advantage over placebo on MASH resolution, with a substantial minority also achieving fibrosis improvement — and fibrosis is the endpoint that predicts outcomes. Mechanistically it is reduced hepatic lipogenesis, increased fatty-acid oxidation, less hepatic inflammation, and possibly a direct effect on stellate-cell activation.

One concrete data point for the thread. Say what you would expect to see if you were wrong, before you look. It is a small discipline and it changes what you notice.

Ask again with the specifics and you will get a better answer than this one.

Moderator note: the sourcing question belongs in the vendor section and has been split out. Tagging this one for the weekly digest.
