Slightly tangential to How to read a Certificate but jason_sac26 reminded me — what is the latest on the oral formulations?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.

Relevant to How to read a Certificate of — here is my latest bloodwork comparison:

Key improvements: A1C 7.6% → 5.5%, triglycerides 217 → 117 mg/dL, hsCRP 8.0 → 1.1 mg/L. All on tirzepatide for 9 months.

The inflammatory marker drop is what impresses me most. Consistent with the SELECT trial's cardiovascular findings.

Want to share my personal experience related to How to read a Certificate of since I think it might help others in a similar situation.

I started my GLP-1 journey in March 2025 at 288 lbs with metabolic syndrome. My telehealth provider prescribed semaglutide 0.25mg to start.

Now, 6 months later: I am down 38 lbs, my labs have normalized, and my sleep apnea has improved dramatically. The How to read a aspect specifically was something that made a big difference in my journey.

This forum was my go-to resource throughout.
