i'd go with a single ester test, more bang for your buck. sources always charge more for sust, and i have no idea why. comes in the same size vial and same concentration as enanthate, but they charge more....hmm... when in fact i've heard a lot of UG labs sust blends are just test e or c mixed with prop. you really think a UG lab will go to all lengths to get powders for the goofy ass tests? i wouldn't think so.
also, what everybody else said.
