Simply don't worry about this if your test levels are normal.
Is normal for GH and test to be higher in the between meal phases of the day than after meals because between meals there simply isn't the anti catabolic stimulus of food... so when a person feeds, levels of those hormones naturally go down because they aren't needed for an anti catabolic purpose or to liberate fatty acids from storage to provide energy - food is more anti catabolic and anabolic compared to the slightly elevated levels of those hormones in an unfed state, and provides more energy than lipolysis in an unfed state does...when fed the body becomes anti catabolic and anabolic despite those hormones dropping because food is more anabolic than normal and natural levels of those hormones.
Similar thing where some people make a big deal about not taking a pwo feed becuase such a feed suppresses GH output... yes it does, but the only reason GH is elevated without the feed is because the body is trying to fight catabolism until it gets fed, and there's no anabolic advantage of trying to rely on that GH because it's far less anti catabolic or anabolic than simply eating something.
What Pillion is talking about is basically the processes involved in the simple cycle of muscle homeostasis, is not something to stress unduly about.
