What's the best way for penis enlargement? Medicine or surgery? I want 8 inch penis.

What you want and what you get from life is often a mismatch. And in this case, it's a completely unrealistic dream! No medicines or surgeries exist for such enlargement, so please don't fall for all the fake scams on the internet. Please appreciate your junior - as long as it rises to the occasion, there's no benefit of having a bigger one.
