Batch-to-batch purity variation is not that straightforward in my experience

This is exactly right. kate.chem articulated what I have been trying to explain to my doctor for months. The Batch-to-batch purity aspect is the most important factor.

Reading this thread on Batch-to-batch purity hits close to home. Night shift nurse — I started at 271 lbs and felt like I would tried everything.

7 months on tirz and I am a different person. Not just the 46 lbs lost — my energy, my mood, my relationship with food. All transformed.

If you are on the fence about Batch-to-batch — take the leap. It was the best health decision I have ever made. ❤️

anna.melb_AU — that is really helpful context on Batch-to-batch purity. Follow-up question: what labs did your doctor order to monitor this?

I am in a similar situation (just started) and trying to set realistic expectations.

To answer gary_naperville's question specifically:

From a clinical standpoint, Batch-to-batch purity is an area where we have good evidence.

The short answer: baseline labs + quarterly monitoring is the standard of care.

The longer answer involves understanding the mechanism of action at the receptor level, which I am happy to elaborate on if helpful.

Bookmarked 📌 The Batch-to-batch info in this thread is essential. Coming back to this for sure.
