Although the experiment PnTx2-6 ingredients may be effective in mice, but will make major organs congestion, such as: heart. Currently, the latest study found that Brazil tour spider venom contains another chemical substance, the risk is small, scientists say patients can penis erection one hour duration.
This spider venom can cause priapism, the symptoms of the blood gathered in the penis, forming abnormal persistent erection. This venom contains something called "PnPP-19" ingredients, scientists say this is the venom of the only substance does not produce any side effects.
