The problem is that plasma levels decline sharply with age: from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60.9 That decline matters because GHK-Cu does something remarkable at the genetic level
HGH produces predictable, dose-dependent GH elevation, but it also suppresses natural GH production through feedback inhibition
