I would agree with Paul1959. As guys age, using Viagra or Cialis, is almost always required. Especially if you start taking hypertension drugs or other medications. Having used all three ED drugs and now on Injections, I prefer the Trimix Injection. In my case, it always works and with an extremely low dosage, I don't have to worry about
side effects. I'm hard in 3 to 5 minutes every time.
