Mark McGwire's brother drops a dime on him...

Some brother this jizzbag turned out to be.

A new book proposal, submitted by the admittedly estranged brother of Mark McGwire, claims the former major league slugger used both steroids and human growth hormone during his career.

In the proposal, first reported Wednesday on Deadspin.com, Jay McGwire alleges that Mark used Deca-Durabolin and that he introduced Mark to performance-enhancing drugs in 1994.

My brother could shoot somebody in cold blood in my house and I wouldn't turn him in...and believe me, that could actually happen!!!
