GHRP-6 vs MK-677
Which should you choose? Here's what you need to know.
The short answer
GHRP-6 and MK-677 are both growth hormone peptides, but they work differently. A growth hormone releasing peptide that acts on the ghrelin receptor to stimulate GH release and significantly increase appetite. Also called Ibutamoren. Taken orally rather than injected, it tells the body to release more growth hormone. Technically a secretagogue, not a peptide, but sold alongside them everywhere.
