DJ, I am curious how you are basing your 17” expectations. It appears to be nothing more than idiotic wishful thinking. You do know that even a boatload of gear won’t make you explode like the Incredible Hulk in a few weeks, right? Even people with freakish genetics and tons of gear take many months or years to put 2” of lean on an arm, and you obviously have sub par natural muscle genetics and sub par response genetics.
