Sorry, I don't know how. Chart shows very little activity for years, even though no dilution or name changes. They are real and solid company that has been working on building business. Backer has been supporting operation through private financing. I saw them make a profit, though small, but shows sales that could be turning point. If I'm right.... could be big move next qtr or b4 then. PPS has been between .01 and .02 for years so I didn't buy any cheaper than you can now. I am buying daily and spreading the word because I do think a run is coming. Once I get the word out and pps moves up I will back off my buying. All I can say is read the last 3 filings and if you think this is a otc scam play plz post so. I see potential buyout if product does well from new sales. bought on speculation, volume and those filings. gl
