All one has to do is go back through two years of history here to see that this OTC blunder, is exactly what it is, a blunder. Do not go through just the message boards, look at the history. $GRST is just another B1EL look it up, over-promises never kept.
This has seen a lot of hope and hope has been crushed time and again. I do not like having a pessimistic view, but $GRST gives no one any hope of positivity.
I feel it like asking for questions on a test, you will not get them from me, you need to research facts for answers.
