You never specified what your goals is... so fuck, i can tell you any one of them go great with test because thats a fact!! GW501516 is the one i recommend no matter what but as far as the others, it depends on what your goal is..
GW501516 is generally going to be the first sarm I recommend on any cycle. As Dylan said, without knowing your goals, it is simply a guessing game because they all would stack very well with testosterone
