What “Research Use Only” Really Means
The phrase is a regulatory category, not a quality claim, a safety statement, or a loophole.
Research use only describes the intended use a seller declares: laboratory or scientific research, not diagnosis or treatment. It is a statement about permitted commerce, not about purity, sterility or effect.
Three things it does not mean
It does not mean a product has been tested for identity or purity. It does not mean any regulator has reviewed it. And it does not mean an approved medicine is being sold under a different label.
Why documentation matters
Because the category imposes no analytical requirement, documentation is the only signal available: a dated certificate of analysis, from a named independent laboratory, tied to the batch identifier on the vial.
