Well, Mr. g101, I have to commend you for going right to the cruxity crux. I agree it's probably the most valuable question I could possibly answer about Kevin Levrone and I'm sorry that I can't answer it.
Even if you knew the stack it would likely do you no good and here's my opinion why (conjecture): the money and backing surrounding Levrone during his Weider tenure financed ungodly amounts of medical monitoring and customization to Levrone's particular physical makeup and hormone level. This kind of monitoring, adjusting and customization is far more valuable than the actual cycle itself. Levrone is a hyper-responder and his stack may have been more mild than you think.
Again, I don't KNOW this, but I do know that asking about Levrone's cycle is a waste of ink. I'm sorry if you think my answer was also a waste of ink, I did the best I could.
