for maximum protein synthesis to actually occurr not just facilitate , max levels of protein intake are required for this "magic to happen" regardless of the steroids anabolic and hypertrophic mechanism. its like building a house, you can have a bunch of workers but if you have no supplies ( food + training stimuli ) how will this house be built? the workers in theory would stand idle past a certain point. it may make the protein you are already consuming more efficient, but that is one of the building blocks required. I used to do hardly any carbs and eat 1.5g kcal per day and take grams of compounds in my 20s. Now I eat 2.5k calories and take a fraction of that and grow way more efficiently and quicker, safer , permitting they are clean calories and bloodwork/cardio is adequate
I have taken 2-3gs at a time of total compounds and had less results then in my 20s , then i do now with hrt dose test, some orals, insane workouts, and force feeding clean food, just my 2 cents, your body needs stimuli to respond to, not just AAS brother, its like doing a ton of coke in 1 night, after a certain point you dont even really get high anymore, just experience the nasty sides.
