​The Pharmaceutical Crime Fighting Unit within the Ministry of Health recently confiscated counterfeit pills, named Sharkessence, which were being sold as a treatment for impotency. These pills were tested at the Ministry of Health laboratories and were found to contain 183 milligrams of Sildenafil (the active ingredient in Viagra) and 27 milligrams of Tadalafil (the active ingredient in Cialis).
These dosages are extremely high, since the maximum allowable dosage in a Viagra pill is 100 milligrams and 20 milligrams in Cialis.  Consupmtion of Sharkessence is dangerous and may be harmful to public health due to the high dosages of active ingredients in it, as well as due to the fear of the presence of other toxic substances in the pills. Furthermore, it is unclear under what conditions the drugs were manufactured, stored and transported to Israel, a factor which increases the risk of using them. 
The Ministry of Health repeats its warning against online drug purchases over the Internet or purchases from unauthorized marketers or couriers. This warning applies to impotency drugs as well. Drugs should only be purchased from licensed pharmacies.
