i'm convinced Wade used GH.   we see how bodybiulders' hands grow.  We see Barry Bonds head and feet size increase.
And we see Wade's jaw growing.  In a huge way.  Asymmetrical manner as well.  Just as his body has become super muscular and stronger/faster - after knee injuries - as he passes age 30... just as he's better than he was a decade ago... 
that jaw growth, sorry, I'm convinced.  And lebron blew up in muscle when he arrived in Miami too/  
and the end of last season, he started shrinking.  Probably got OFF the gh when the MIAMI clinic with A-rod and frends got busted.  Come to think of it, they got busted right before the 2013 season.  Wade missed 1/3 of the season injured and sucked in the playoffs.  Lebron was completely tired and weak by playoffs.  Bosh had no muscle, no balls.  I'm betting the Big 3 lost their connect before the 2013 season, and that's why they lost so badly to the spurs.
