In your case, which was also mine, your body stopped producing new proteins by amino acids to be joined into new muscles fibres, since a few years already.
You can literally kill yourself into the gym and eat amazing amount of macro nutrients but the only thing you will achieve is to make bigger your own proteins... not to make new ones.
To answer your question, yes with aas you can either increase the size of your own proteins or make new ones.
Think it like this:
Testosterone and all derived substances:
You have a building and can, with those aas, increase the floors of it only.
HGH
You can build new buildings over the one you already have.
Hope I was clear.
So, either you want new floors or a new building, Good Luck with your cycle.
