I am trying to understand how a muscle such as the bicep grows step-by-step. For example (but not limited to):
- How nutrients line up?
- Which are essentials?
- What exactly do they do?
It's hard to make sense of the process when potein, bcaas, glutamine, amino acids, complexe carbs, simple carbs, con-cret creatine, mono creatine, calories, weight gainer, pre, intra, post workout supplements all seem to promote lean muscle.
I'm looking for a physiological answer.
