well one member here told me that for and adult to have the same test levels as a natural guy my age they would need t be one about 400mg a week. so maybe if you are still yougn and you do proper pct and do a high fat diet like anabolic diet, body opus diet, modified atkins diet....just some kind of carb rotation that allows for high cholestrol... i think one MAY be able to at least keep some of the gains
big thing though is muscle mmory, like whe luke wood shrank way down when he was sick, but only a couple months back on and he was return to normal size
