Compounded vs Brand Question

I just switched last Wednesday from name-brand Zepbound to compounded tirzepatide with L-carnitine and things feel a little different. It doesn’t seem like it’s as strong (if that makes sense) as the name brand. Why you ask?

I am having some food noise today, I noticed both my knees are a little achy when going down the stairs, and I feel extremely hungry today. These things were nonexistent when on the name brand. And to top it off my weight loss is less than a “normal” week. I’ve been pretty consistent since the very start.

Has anyone else experienced this when switching?Could this just be a fluke week? Or is there that big of a difference between compounded and name brand?

It’s not enough to make me switch back to name-brand, just wondering if this is a typical transition.

Thanks in advance!
