orals only? hgh? some ai's?

hey guys, just wanted your input on what greg plitt's cycle might be or if he is just on hgh. definately looks like he was on hardcore cycle a few years ago from old pictures.

But he is smaller now and more fit for generall fitness magazines ect..

So what do yall think.

this is one of his more recent videos. https://www.youtube.com/watch?feature=player_detailpage&v=K_sjlodccYg#t=140

^^ the delts dont look that capped at all- but he looks good... hard to tell.
