Shreholders sometimes complain that PTK could do a better job of keeping their shareholders informed of their progress ..   Tetro Bio Pharma certainly does a good job of that,, 4 NR s last week with many more to come..  TPB  is finally coming back to life and getting pretty exciting for shareholders with huge vloume days recently  as they are getting closer to some of their goals with a lot happening in the next few months proving that volume does proceed price..  It makes investing in small caps fun again...
