What a certificate of analysis actually proves
A COA is a lab report on a sample, commissioned by the seller. That is worth something, and it is worth considerably less than it is usually taken to mean.

Regulatory movement, what the research actually establishes, and changes to how this site works. Positions in this category move, every compound page carries the date we last checked, and when one changes it gets written up here rather than quietly edited.

The label is a legal position, not a quality grade. It says nothing about what is in the vial, and that is the point of it.
GLP-1 compounds: the gap between the trials and the vial
Semaglutide and tirzepatide have large phase 3 programmes behind them. What those programmes tested was a manufactured medicine, not a vial bought under a research label.
