Switched to different

Hi, I’ve been using compounded semaglutide for 12 weeks now, just completed my 1st 4 rounds of 1mg weekly. And as I am with an online company, I get it sent monthly to me. Today I opened package and it is genuine Ozempic brand in the one pen. Should I be concerned about the brand change and side effects being different? My normal injection was a single syringe with the 1mg in it/. I’m a bit concerned.

Thank you
