OP here — wow, did not expect this much response! Thank you all for the thoughtful replies on Peptide Sciences quality.
To answer marcus_mpls: 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. 🙏
Relevant to Peptide Sciences quality was — here is my latest bloodwork comparison:
Key improvements: A1C 7.6% → 5.5%, triglycerides 205 → 105 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.
100%. My provider said the same thing about Peptide Sciences.
Certified reference materials, analytical reagents, and research-grade standards for peptide verification. Trusted by laboratories worldwide.
Shop Reference StandardsSlightly tangential to Peptide Sciences quality but hannah_MT reminded me — does anyone have experience combining this with metformin?
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.

This is exactly right. PurityPaulOR articulated what I have been trying to explain to my doctor for months. The Peptide Sciences quality aspect is the most important factor.
