I have searched around quite a bit through this website and several others looking for an answer to this question:
Lets say you have two individuals completely identical height,weight, ect, neither of them have ever trained before. Both are 25 years old the only difference one has a Total Test level of around 600 and the other has a test level around 800. They both begin to to workout doing the same exact lifting program, diet, ect.
Will the individual with test levels in the 800s have the ability to put on significantly more size and build more strength short term 3 months and long term 1 year than the individual with test levels in the 600s? Or is a 200 difference in testosterone not significant at all?
