for a skinny guy trying to gain weight and muscle mass, currently on igf lr3, I know Mm677 increases appetite which is great what other factors dose it have? And is it a good Combo for my current stack.

Hey looking for for feed back, I'm Joel Im 6,1 180 pounds Naturally skinny and athletic, I'm currently running these two Peps while eating good. Should I add anything or what advice do we have to put on as much possible muscle.
