I think 'NO'.
I have been doing research about various penis enlargement methods; from my research I don't think there any method which can help men to increase their penis.
I don't think any exercise, surgery, pills or device can increase our body parts.
Most of the products and methods are fake and non effective.
However I got chance to interact with some customers, who bought products from online.
They tried almost all methods and done every surgery also.
They desperately need bigger penis because they partner left them because of the small penis and couldn't satisfy their partner while doing sex.
Few agreed that they could increase one or two size by taking herbal or natural pills for long time.
Not only they increased size but they had sex for long time.
I asked them which product is most effective.
They said that 99% products are no effective and doesn't have any effects as well as any side effects.
Since there is no side effect no one complain about that because this is really embarrassing issue.
According to them we have to check the ingredients of the each product, some herbal ingredients can make some difference if we take without default.
Before buying any herbal pills, check authentic review site which can give details about the ingredients and success stories also.
I still feel that chances are very less; however herbal pills can make small difference.
If we take some good pills for long time, I am sure that penis enlargement is possible, but never try any surgery, exercises or devices which can even impotence also.
