Enzyte is a controversial herbal nutritional supplement manufacture by Berkeley Premium Nutraceuticals of Cincinnati, Ohio. The manufacturer claims Enzyte promotes "natural male enhancement", which is a euphemism for penile enlargement, increased duration and firmness of erection and increased sexual stamina. However, its effectiveness has been called into doubt and the claims of the manufacturer have been under scrutiny from various state and federal organizations. The manufacturer's founder and CEO, Steve Warshak, and his mother Harriett Warshak, have been found guilty of conspiracy to commit mail fraud, bank fraud, and money laundering.
