yeah bro the more advanced a user gets his or her understanding of feed times and what macro to feed on at what times. The influx of insulin from carbohydrates when and where do they need to be staged. Are you wanting to initiate catabolism and drop weight and sacrifice muscle? How to tap into short windows of catabolism and trigger a fat zapping cardio session. It's funny how a singular topic can be made to be understood very easily and if you really wanted to get detailed it can also be made into a college thesis paper. Thanks to all of the old school cats who told us do this or do that and we learned that those tricks worked even if we didn't understand why. Fast forward to years in the game and studying the actual reasons why fasted cardio melts fat. Or why HIIT can actually trigger EPOC and burn calories(fat stores)for well over 24 hours and in some studies it's been shown to burn for up to 38hrs.
The repairing of cells and oxidation of lactic acid from high intensity interval training all takes energy to make it happen. I did research a long time ago with my boy Cdaddy on the secret muscle building of lactic acid. It gets a bad rap but that shit is a precursor to blood doping if used properly.
AAS I've noticed can and will do some amazing things without a single minute in the gym if used with a razor sharp diet. Food is The single most anabolic substance we can put into our bodies. So just imagine what a workout program or matrix mixed with AAS and a diet fit for a specified goal can do. It's symbiotic. Connected, linked and exponentially proportional. The stars align and the sky is the limit bro. I love that shit.
