Medically approved devices?
So I come across adverts or penis extenders or stretchers that claim to be medically approved by FDA blah blah but what is the truth to such claims? Is there anyway to see proof of this FDA certificate? Without this the claim is nothing but b.s.sales talk. Is there a stretcher or extender that is the most popular due to a possible FDA certificate? I am trying to look for one that could be the most widely used due to its reputation for being safe. So is there any true FDA validated ones?
Also what is generally better between hanging weights and a penis extender/stretcher? I am a newbie and am exploring all options. I am a little skeptical of jelqing so possibly want to start with a device with minimal stretching then gradually increase over time. Also do you have to use for 1 day then stop for a day then use again? What is the process on average?
