Post steroidal breakdown.
From GeoffShackelford.com, here is a quote from a story yesterday:
Brian Greenspan, a Canadian attorney for Galea, later confirmed that Woods received treatment from Galea but that it was plasma-rich platelet treatment and did not involve human growth hormone.
"He did not receive Nutropin [a form of HGH]," Greenspan said. "In fairness to Tiger Woods, he received only one of the four treatments."
