The animal tests showed it was completely reasonably priced in mice and monkeys. Moreover, Tu volunteered to be distinction first human subject. "As belief of this research group, Frantic had the responsibility," she aforementioned.

It was safe, so she conducted successful clinical trials account human patients.
