The AP is reporting that Andy Pettitte’s father got the HGH he supplied to his son from one of the pitcher’s ex-high school teammates.

Kelly Blair, who owns a gym in Pasadena, Texas, was the source of the substance, the New York Daily News reported Sunday.

Pettitte, who has admitted using HGH in 2004, told congressional attorneys that he received it from his father, Tom Pettitte, whose has had serious health problems. In his deposition, Pettitte said his father got the drugs from a trainer at a gym where he worked out but did not identify the trainer.

The Daily News reported that Blair sold HGH and steroids to customers at 1-on-1 Elite Personal Fitness. Blair did not respond to the newspaper’s requests for comment.

Weird. Even stranger is the fact that Pettitte got the HGH from his daddy.
