ThermaFreeze TZPC - Pumped & Dumped I bought this stock on accident when the news about dry ice shortages began circulating. My buy was based on an internet article that recommended this "dry ice stock" but many found out that TZPC is not a dry ice manufacturer and has no realistic solutions for vaccine storage and transport. With no news or reports about the company during the time of the pump it can be assumed that many people poured money into this stock thinking they were investing in a dry ice manufacturer but there were not.
