this is a great question i would like to know as well timing is everything i would assume, there is no way guys like evan and kuclo are geneticly gifted there is some time of dosing eating or training protocol those guys follow to become monsters.
You know the average HRT dose is 150-200mg test per week, but why do you think some endo's prescribe only 50mg and some prescribe even 400mg ?
after all they are all trying to hit the same sweat spot of test levels for healthy individual,
it's because different people respond differently.
now it doesn't mean that Evan and Steve are prepping with 500mg of test for major pro contests, but one thing for sure is that they will get way more out of this 500mg than you will ever dream of.
