Realistic.... $6 - 8, so many variables, lots can happen. Only good test results and file for FDA: $5-7. FDA approval and actual sales..... Depends on the sales numbers, 1mil... $10 more than a mil and continuing sales in EU, 20+ with maybe a much higher initial pump on all this. Downside, plenty of them, any issues with testing, further delayed testing, run out of funds again, more dilution. Not receive FDA approval, this stock goes pink.
