Because the body naturally releases GH postworkout, under your theory eating postworkout would blunt this and hinder recovery (GH not present) and as bbers we know postworkout is probably the most important meal.
Sure we were meant to grow but that's only up to a certain age. After that we are done growing, we only recover. Naturally we don't grow like we do on PEDs, this is why I see a flaw in your theory. Those old theories were based on the natural hormonal system becuase we didn't have all the studies we have today on exogenous hormone use. We HAVE found out since then that exogneous hormones are not simply going to work like the natural process. Once we inject exogenous hormones we have disrupted this. The feedback loop alone will disrupt hormonal release, so thinking cuz you pin GH in the day that your body will release GH that night as you sleep is wishful thinking! Somatostatin levels will be high from the length of time GH levels were elevated which is 8-12hrs with exogenous HGH, why would the body release GH that night when it's been getting negative feedback for roughly half a day? You disrupted the process brother.
Just like After you inject test, its over for the natural production. And with slin and gh, it's the release of the hormone that is inhibited, not the activity. So when we inject them why would they not work? They are not being released, they are exogenous so inhibiting release is not a concern.
No argument brother, just food for thought.
