If anyone here can confirm how HgH is used that would be cool.
The reason I ask is because if Pettitte used HgH like he said he did, I believe it would have done nothing for him. I was under the assumption that HgH must be used every day to be effective. If he did it twice in '02 and once in '04, it would have no effect.
Now, whether he's telling the truth or not is a different story. But if you believe he used as he said he did, would it have any impact whatsoever?
