Test is test. The only difference betweem the esters is how long they take to be absorbed from the injection site into the bloodstream (the half-life).
In the bloodstream catalaze enzymes strip the ester away and leave free testosterone which is what activates the androgen receptors. Therefore the androgen receptors have no idea what ester USED to be attached to the test molecule.
So, as long as you know the half life of the product you're using and choose a dosing schedule that provides even blood levels (this may require front loading for high half-life products); the same results can be obtained with any test ester.
In most cases, my recommendation is to stick with enanthate since it is the least expensive per mg of test. If you're only doing a short cycle, want the test out of your system fast, have a high tolerance for pain, and don't mind daily injections, then test prop is the best choice.
