Regarding hearing from the horses mouth. I heard a semi-funny story today. One pro ask another pro how the hell he made his recent insane gains. The answer was: ask my trainer. Which is pretty much same as saying you'll never know.
Sounds like Phil and Hany do not talk about their regimens to anyone, not even other pros. Close friends like Skip may be an exception. Which is understandable knowing how gossip and shit talking spreads.
There are no secrets of course, but no one wants others to think their gains are due to drugs.
