Clinical perspective on Is 98% purity actually good or should I:

I have managed over 200 patients on GLP-1 therapy and this topic comes up frequently. What the data shows — and what I see in practice — is that the medication works best as part of a comprehensive approach.

For this specific question, I would recommend: getting comprehensive baseline labs first.

Reading this thread on Is 98% purity actually hits close to home. Night shift nurse — I started at 275 lbs and felt like I would tried everything.

11 months on tirz and I am a different person. Not just the 50 lbs lost — my energy, my mood, my relationship with food. All transformed.

If you are on the fence about Is 98% purity — take the leap. It was the best health decision I have ever made. ❤️

This is exactly right. lori_vegas articulated what I have been trying to explain to my friends for months. The Is 98% purity actually aspect is what made the difference for me.
