Mk677 is definitely effective but In the opposite of gh. Mk makes you hungry af and gain weight like crazy.
The difference between most grelin peptides and hgh is the hunger.
Ipamarelin is the cleanest peptide as far as hunger and prolactin.
Gh takes a month or two to clean up your abs in my experience.
Ipam may be a little slower but it's a cleaner compound than gear or sarms.
If you want to mix it with cjc 1295 dac or no dac it will compound the effects.
At one point I was running mk677 hexarelin and cjc 1295 dac together. The hunger and fatigue was insane. I longed a bunch of crazy peptide cycles on prohormone forum
