Ipamorellin is a third generation GHRP. It's not necessarily superior - as it is said that GHRP-2 is more bang for the buck - but it is said to cause no motility or hunger issues. However, it does not cause as strong a GH pulse as the other two peptides. It's also more expensive. But you can find all this info readily available where I did - at datbtrue. It's worth going there to do your own research.
