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

To answer VendorMark: 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. 🙏
