For what it's worth, I spoke to Brian Wallace, the former COO, and he said the project is anything but a scam. He said the project is "legitimate" and even he, then no longer an employee, had lots of shares in the company which he did not intend to sell. PGRX may be a bad investment, it may be a high risk investment, and it may even be buyout potential investment, but it is most certainly not a scam.
