Thanks for sharing this, VendorMark. A few questions about your Master verified experience:

  1. What dose worked best for you?
  2. How long before you noticed appetite suppression kicking in?
  3. Did your endo have any specific recommendations about Master verified?

I am in a similar boat and trying to learn from others' experiences before my next appointment.

Clinical perspective on Master verified vendor directory Q2:

I have managed ~150 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.

OP here — wow, did not expect this much response! Thank you all for the thoughtful replies on Master verified vendor.

To answer lori_vegas: yes, I am on compounded sema from a 503B pharmacy.

Quick update: things are still going well. Thanks again for the evidence-based discussion — this is exactly why I posted in a science-based community. 🙏
