I would never pay for a prep coach. I have heard of guys paying Farah $3 K for their prep. This doesn't even include drugs!
I understand that a prep coach makes your life easy, but jeeze, doesn't this take away some of what bodybuilding is about. $1,500? $3,000? That's 10-20 Kits of high quality hgh!! Besides, shouldn't we all be striving to learn our own bodies? Shouldn't we want to learn what food and training methods effect us the best? Isn't bodybuilding supposed to be a learning process?
I don't think there is anything wrong with sending people photos and getting feedback, making adjustments and seeing how they effect you according to that feedback, but to pay someone all that money for it... sorry, no way. I started an offseason progress thread on here about 2 weeks ago. I got 5+ pages of feedback for the cost of $0. I prefer that price, thank you.
