Drake and Josh. Hope that helps :)
Hemlock Grove is pretty bromancy...
Here..
Boy Meets World. Burn Notice. Memphis Beat.
The best televised 'bromance', in my humble opinion, is the one lived by JD and Turk from 'Scrubs'. They are open and unabashed about their status as long-time best friends, which is a refreshing departure from the usual tropes followed by male characters in television shows.
Alternatively, you may want to try Supernatural, although the fact that the two characters are actual brothers may disqualify that particular series from the 'bromance' category.
Entourage provides the greatest bromance the world has ever witnessed. Running from 2004 to 2011, Entourage follows the life of Vincent Chase, a rising film star aiming to conquer Hollywood. Vincent is accompanied by his brother Johnny, and best friends Eric and Turtle, and together they find themselves in all sorts of weird situations, usually involving cars, women, and too much partying.
Entourage provides fun, laughter and plenty of drama, but most of all, it delivers a truly believeable bromance.
