I like the convenience of mk but really have to watch the bloat. Ghrp has less bloat but the multiple inj are a pain in the ass. I do feel mk has stronger affects than ghrp2@3xdaily. Clinical trials in AD patients showed a 60% increase in igf at 6weeks and a 72% increase in igf after 1 year while using 25mg mk-677. It was also shown in younger men to increase stage IV sleep by 50% and REM sleep by 20%. All in all I find mk to be superior to ghrp/cjc with the exception of high dosed ipamorelin.
