This is a database compiled by the Human Performance Resource Center, a federal program that keeps track of health issues affecting members of the U.S. military. The database shows products with DMAA on the labels that the center said are still available online. It was provided to the AJC on Oct. 23. Because four soldiers have died after using DMAA products, the issue is one the HPRC has monitored closely. Program administrators say they attempt to update the database monthly by checking web sites.
