I think you've got that backwards darkhalf. 6 is less likely to raise prolactin and cortisol. 2 is stronger but tend to raise prolactin and cortisol to the higher end of the normal range. 6 makes u hungry. 2 not so bad.
Are u holding water? I added hexarelin at night and held five lbs of water. Some people say ghrp-6 makes them hold water. I stopped for a couple days, made sure my diet was in check, and everything is back to normal.
