I am only assuming that the breakdown of the test in Sust is the reason giving for taking so much. I have heard that test is test, but cyp and e at gram you would only be getting around 200 mgs of each, which is basically 400 of the long ester and round 150 of the short prop ester. My Sust has about 5 diffrent blends in it, just trying to get the most out of it.
