I am at the age of fifty and have erection problem even my partner is in my bed

Welcome to older age. Do you take any medication, blood pressure, sinus, others, they can all cause this, and viagra would not be one of the largest selling medications if there was not a lot of people with this issue.

Plus it can be caused by various medical issues, sounds like time for a check up with your doctor.

It happens, Viagra will help.

If it makes you feel any better, the biggest users of viagra are now under 25 so to last until your 50 without needing it means you're doing well.

Hope this helps,
Louis.

They claim beta sitosterol is good
It is found naturally in many fresh green vegetables like green peppers.
Or you can buy beta sitosterol pills at GNC
Saw palmetto is suppose to contain beta sitosterol if it is a good brand but
The beta sitosterol itself is probably better.

Eating fresh green veggies you can't go wrong anyway even if it doesn't seem to help any.
