Update 10/20/2019: A new metastudy done by scietists from Italy and the UK reviewed several non-surgical and surgical approaches to increase penis size and evaluated their risks. The results are fully in line with out own and support the statement that penis surgery and almost all of the devices and pums sold for enlargement present a high risk and very limited results.
Even worse, many of these pills contain undeclared substances to make buyer believe the product works. There are hundreds of different so called penis enalrgement pills on the FDAs official “Tainted Sexual Health Products” warning list, including some very well known and popular pill brands. The hidden drug ingredients are often Sildenafil (Viagra), Tadalafil (Cialis) or Vardenafil, subtances used to treat erection problems, short ED (erectile dysfunction). While these prescription only drugs can help patients suffering from ED, they can also have dangerous side effects and interactions, especially for people taking certain cardiac drugs. In the worst case, they can cause heart attacks, there are several verified actual deaths related to dubious penis pills. Don’t risk your life and stay away from enhancement pills, no matter how tempting the advertsing or fake reviews sound. My advice: Go for effective natural training instead.
However, after more than a century of generally dubious and sometimes lunatic penis enlargement attempts, there's still not much you can do. Sure, there are lots and lots of supposed options out there -- penis pills, creams, brutal stretching exercises, horrific-looking devices, and penis surgery. Almost none of it works. The few approaches that can work often have modest benefits and serious side effects. How serious? In some cases, erectile dysfunction-serious.
