The problem is what your missing when you don't get the appetite is the Ghrelin stimulation. It is the Ghrelin that makes your burn fat better and it also stimulates cognitive adaption to changing environments.
So you miss the awareness effects, one of the biggest positives over rhGH.
Besides the hunger goes away as soon as you eat, its not like it stays up all day.
I actually like having a way to control my hunger, I actually find I eat less overall.
The best way to boost the secretion is to add L arginine to the GHRP-2
Synergy of l-arginine and GHRP-2 stimulation of growth hormone in men and women: modulation by exercise
Remember GHRP-2 can effect prolactin. So its not all gravy either.
the reason to put more than one together is because each has its own saturation dose. you can get a bigger stimulation with less MCG by combining them. They have a very synergistic effect together, they both attenuate SS and spark GH secretion simultaneously.
