I have been using GHRP/GHRH peptides for quite some time and love the results. The effects I've noticed are better sleep, feeling of well-being, fat loss, skin improvement. I decided to try out MK-677 because as it's a growth hormone secretagogue as well I thought that I would get similar benefits, and it's way easier to dose it because of the long half-life. Injecting 3x times a day is a pain in the ass. So I tried MK-677 yesterday before bed but couldn't fall asleep after that. It felt like my BP increased. I am not sure if my body simply has to get used to it because I found it pretty annoying. I will probably dose in the morning or midday from now on because the time of the day shouldn't make a difference as it has a long half life of 24hrs. Do GH pulses get weaker after about 8 hours? If yes then it would probably be better to dose before the bed.
