I have been wondering for some time that when you are on a cycle of say 500mgs of test per week and your natural test shuts down does it still matter to boost testerone by doing legs and other big muscle groups that would normally boost your natty test?
I know that the big muscle groups are important to do and Im not asking that question I am just wondering what the logic is behind the natural test production shut down and if it can still be increased by building big muscle groups when on a cycle
