I've only used Teraxatone witch I did like so I can't really answer your question. However, I thought I would chime in because this is a subject that has been on my mind lately. I'm in the middle of a cutting cycle right now, and I have been thinking about doing the same thing. Every year I use july 4th as the deadline to exeed my all time best shape. last year I got down to 5%bf but was kind of flat. This year i want to take it all the way and do it right. Carb loading, water restricting,and mabey some glycerol. These are all tools I want to employ, but I have yet to get the timing right. I would love to hear some input from those who have experience in this area too. My goal is to prep for a pic that i want to use for my avatar.
