Has anyone independently verified an MKM semaglutide batch COA?

For reference: MKM · semaglutide.

Somebody stated this to me confidently and I would like to check it before repeating it.

I would accept a well-reasoned negative answer over a poorly sourced positive one.

How well supported is this claim?
