Should I stop taking zepbound?

Started zepbound may 2025 and as of today I lost 110 lbs I'm now 265-270. I've been on 15 MG since about October December, I haven't lost much weight since January I've been floating around 265 for 6 months now while still taking my 15 mg shots. I'm eating the cleanest I've ever eaten. More active then I've ever been, best physique of my life. Work out 4-5 days a week. Ive been eat 200 grams of protein per day for a few months now and been taking creatine since November. I've built up a lot of muscle since then so I guess my question is, is the weight that I should be losing is actually converting to muscle? This being the reason I'm now losing but also getting stronger? Or am I just immune to zepbound now?
