Can't help with shorting,don't know anything about it.The thing i am pretty sure of is aagp cannot be ignored.According to Ross Senior pktx is a small company selling it's product to very large companies.As for the cosmetic industry cell preservation is something they are not used to dealing with.This is why his approach to marketing has changed.As everyone knows pktx (as for now)is operating on limited funds.If all the things come to play that were discussed we should see an upturn pretty soon.We all are frustrated by the stock downturn.I'm still strong on the company,but time will tell.Hang in there.
