Does insulin come from China?

Could you please clarify if insulin, a hormone produced naturally by the pancreas in humans and some animals, is sourced from China? Is there a misconception that insulin, which is critical for managing diabetes, is exclusively or primarily manufactured in China? Are you asking about the origin of insulin's discovery, production methods, or perhaps the sourcing of insulin medications on the market today? Understanding the context of your question would help me provide a more accurate and informative response.
