Jerginsa,
I doubt you need to be in any hurry. Seems to me this stock isn't going anywhere materially higher anytime soon - can't see a reason for it. Maybe as results from these trials draw much, much nearer, yes, I can see a mini run from, say $1.50 to $2.25.
We'll all have a chance to purchase shares for far less than Al Mann did this last go round. If we're really lucky, perhaps we can buy them as cheaply as OPC will.
Good luck and hang in there. It's a matter of time, but, unfortunately, still plenty more of it!
