What does "Research Use Only" mean?
Research Use Only means exactly that: intended for laboratory and research settings only, not for human or animal use, consumption, diagnosis, treatment, cure, or prevention of any disease.

As a vial of lyophilised (freeze-dried) powder, sold for laboratory and research use only.
