Sermorelin and GHRP-2

Ghrp-2 200 mcg when wake up
Sermorelin 300 mcg before bed.

Any issue with the doses outlined above? I see up to 500 mcg Sermorelin is the top end of "recommended". Is more better?
Any issue with choosing GHRP-2 over GHRP-6?

How long before cycle to start this routine so as to maximize cycle impact?

Thank You

I hear 300-350 people get great results with sermorelin

I've used both ghrp and I'm always hungry anyways lol
