Compound results versus Mounjaro

My insurance recently started denying my coverage for Mounjaro. While waiting on my doctor’s office I ordered from Fifty 410. I was steadily losing 3.5-4.0lbs per week. I gained 2.5 my first week on bud and this week leveled back out. Has anyone else stalled when switching? The pharmacy is having me take my injections twice per week. I am at 5mg and I was on 5mg of Mounjaro.
