I cant imagine the FBI having any interest in GH. The DEA? absolutely, the FDA for sure (HGH related). Various other branches of LE yes yes and yes.
We could easily sue GH right now our attorney has no problem with the information already on hand it is g2g/ With a lawsuit there would be court orders for all of his information that would be complied with by all of his information providers. I personally think it sounds like way more of a hassle than we've gone through so far - it sure would be for him.
So now what?

You gave us much entertainment.
You were our white knight that brought down the Villain.
Now he's bounced back and is continuing on his journey of deceitfulness and tomfoolery.
I for one would like you to go through the hassle of suing him. Although I just sit in the audience and enjoy the show. I have no idea what it would be like to be part of the production. Drama is not my forte.
I encourage you to bring him down the best you can. However I have two motives behind this.....one good and one not good but not bad either;
1) Look at all the people he's hurt.....he has it coming.

2) It would just be so goddamn funny.

You would be an internet legend in the bodybuilding community...that's for sure.
