Has anyone independently verified a BCH a GLP-1 receptor agonist batch COA?

Asked 1 Jan 2026Modified 7 months agoViewed 4k times

What I am working with: BCH · a GLP-1 receptor agonist.

This has the shape of a fact but I cannot find its origin.

What I found instead were three secondary sources all citing each other.

Can anyone point me at a primary source, or confirm that there is not one?
