Scientifically speaking, I am not so much a fan of PLUG, I think FCEL has all the right stuff, been with that for over a decade.
They're all good I guess, if you know how they trade.
Apparently NWBO is delaying their 10-Q and taking too long so I exited that one, right/wrong, looks bad.
Can always get more.
One thing to note when we ever report is whether or not there is any indication of auxiliary products that seemed to make a difference. Synergistic Adjuvants, and jump on those.
