Lybalvi question

Does anyone know the difference between Lybalvi
Which is apparently olanzapine and sampidorphan combined compared to just olanzapine. Is it just a hunger/weight gain thing or is there another chemical? Thanks

Has anyone tried both? Has it worked?

I hear that the weight loss is usually not so significant with Lybalvi but I could be wrong.

I don’t know too much about this drug either
It’s brand new
