where can i watch all the series of nip tuck online?

Try this:

www.niptuckdownloads.com

Download Episodes Instantly. A Deeply Superficial Series Online

they have seasons 1-4.

you are being a pirate by doing this!

Why don't you just out and buy or rent them on DVD? It's illegal and against the law to do what you want to do.

You are breaking the law by doing this.It's illegal. It's illegal privacy. Movies,software,music are all "intellectual property" . This means that studios etc can fine you a lot of money.I know for movies on DVD it's $250,000 or 5 years in jail. Is is really worth that just so you can see them for free?
