Agreed, there is a paper on here that someone posted that showed the gains in increasing dosages for TRT therapy in older men. There was a dose response curve but they only went up to 600 mg/week in the study. The poster graphed out the continued dose response curve if it was continued on theoritical dosages.
If someone has a link to that article post it up, Im over trawling through this forum today
The graph is under Testosterone Enanthate on the steroid.com webpage. It shows a 15 percent increase in lean mass. The study maxed out with a 6 month 600 mg Test E cycle.
