I was comparing cheaper semaglutide brands and got confused

I've been seeing different semaglutide brands available at different prices and I am trying to understand what patients should actually compare.

A lower price is obviously attractive, but I don't know what evidence or information matters when deciding whether two products are comparable.

For people who have researched or switched between semaglutide brands, what questions did you ask? Did you look at approvals, manufacturer information, clinical evidence, or discuss it with your doctor?

I'm interested in understanding how people evaluate options beyond just the price difference.
