I was gifted this book last year
Certainly some fascinating concepts towards sports nutrition. While a lot of it may have been multi level marketing, there was some awesome pickups from it. For example, if you’re bulking - buy some maltodextron (super inexpensive) powder to add to your protein powder, if you work out hard for that 30-60 minutes, up to 220g of carbs can be taken in - spiking the insulin back up to regular levels to get you back into recovery. Ideally train twice a day with this. I used it, definitely works well, added some easy mass. Only issue is if you have it without doing a workout - the high GI content of it will make you fat if you spike your insulin so much.
There was a couple other amino acid supplement manipulations for improved growth hormone release, however from my experiment there wasn’t much difference between taking them or not if you were training twice a day and having the maltodextron and protein post workout.
Definitely some awesome supplement knowledge and nutrition knowledge in this gem
