I would strongly suggest potential investors stay away from this company. They have not put out a PR for over 4 years and no financial statements since their inception over 9 years ago. Tubercin has been out for like 30 years and has not amounted to anything.....STAY AWAY. OIMHO
PS I have no idea how the SEC can even have this company listed...they should delist it...however, I don't think you can even trade it
