I have the same exact questions regarding Neville. I feel like he more or less uses the same plan for everyone but tweaks it a little bit here and there based on your stage and what supplements/medications you're currently on. That's just my hunch though.
Even if there's a 5% chance that his advice will help me, at this point I have to take that chance. I already ordered his A.C.E. and Licorice. I am really hoping that $300 initial consult is worth it.
