Indestructible (2009)

A man with horrible psychological problems snaps and goes on a short murder spree before being gunned down by the local Sheriff and his deputy. What should be the end of the story is only the beginning as an ambitious doctor decides to test his latest experimental drug on the body of the man. In a Frankenstein-like twist, the drug works all-too-well, and the man comes back, now with super human strength and is near indestructible.
