Is MK-677 The Best Legal HGH Alternative?

[Auris]

All know that MK 677 Ibutamoren (Ibutamoren Mesylate) is a powerful supplement that you can use to improve your health to include metabolism, strength, longevity, bone density, and cognitive ability. But my question is, Is it the alternative of HGH? Or Something like that? Is MK need PCT in cycle?
