Don't get me wrong for a all day event having Dave talk id go for hell 50 bucks maybe no questions hes a smart guy and I'd like to hear what he has to say.. For 750 I can get any training cert in the country. Which you can do something with..
A training "cert" is one thing.
Knowing how to use advanced bodybuilding supplements, at high levels? That's very valuable. A guru that knows how to do that is worth their weight in gold.
I don't use gh, igf, insulin, etc, and if I did, I sure wouldn't want a "Trial by error" phase or reading a bunch of broscience, differing all over the place. I'd sit down with someone HIGHLY knowledgable on the stuff, and learn it. It could save a life. Again, not the world for me, but the shit people are running today at the top levels is very high. Contest cycles and week-of prep? Palumbo is smart when it comes to that stuff, no doubt about it.
We've seen what bad trainers/"gurus" can do to some of the upcoming stars. Over-bulking or hospital trips.
