Male Ultracore Several studies have been conducted on whether male enhancement pills for enlargement (not sexual enhancement) work as advertised. Not surprisingly, most of these tests have been critical, since none of the third-party tests performed on many of the popular pills have shown ANY objective improvement test. However, what was a surprise were some of the ingredients that were found under the microscopes of several of the laboratory tests performed by universities and impartial laboratories alike. For example, at the University of Maryland, several pills were found to have dangerous levels of toxins, including, but not limited to, E. coli, fecal matter, lead, pesticides and more. The California Institute of Flora published SIMILAR results ... arguing that the study of U of M was a weak anomaly.
