"exosomes are a hot topic now" I think this is the key phrase from Wook's buddy. PPHM loves to jump on the flavor of the day. When the bird flu was hot, Bavi cured that. When Zika was hot, Bavi cured that. When West Nile was hot, Bavi cured that. When the swine flu was hot, Bavi cured that. Jump on board.
