I work out hard and have been for years. In pretty good shape for my age and still doing all of the compound exersizes, etc. I have been reading about Diesel Test Pro and would like to try it, but thought I'd seek some advice before I purchase. Would I benefit at my age? I tried T911 and had some good results, as in more intense workouts for the first two weeks. After that it seemed to level out. I tried Stoked and had minimal results. What I am looking for is basic...will it do for me what is says it will do? Will it come close? Diet is good and I get plenty of rest.
