GHRP-2 will make you hungrier. But that is just masking the problem. You need to figure out which compound is doing this to you. It's difficult to diagnose this issue because you stopped two things you were running and then added mast, so it really could be any of those three changes that screwed up your appetite. Or a combination of all three changes. My only advice would be to start next cycle with only compounds you are familiar with and then add one thing at a time to see how it affects you. If you make too many changes at once, you will just be guessing.
An equation like the expectations-augmented Phillips curve also appears in many recent New Keynesian dynamic stochastic general equilibrium models. In these macroeconomic models with sticky prices , there is a positive relation between the rate of inflation and the level of demand, and therefore a negative relation between the rate of inflation and the rate of unemployment. This relationship is often called the "New Keynesian Phillips curve". Like the expectations-augmented Phillips curve, the New Keynesian Phillips curve implies that increased inflation can lower unemployment temporarily, but cannot lower it permanently. Two influential papers that incorporate a New Keynesian Phillips curve are Clarida , Galí , and Gertler (1999),  and Blanchard and Galí (2007).
