i know im a tottal newb at this and all but this doesnt effect my awesome research skills as a student lol on Wikipedia i know i know Wikipedia the best information site in the world but it can be informative and can lead you in the right direction sometimes with the references but anyways sorry for your friends condition and heres what Wikipedia says about ghrp:
"GHRP-6 may also affect the central nervous system by protecting neurons as well as increasing strength in a way very similar to the way certain steroids in the Dihydrotestosterone family do."
however i dont know much about ms either since im a computer science and computer engineering major(s) but i do know ms affects the cns central nervous system and ghrp can do good things so im told thru reading and my own research im sure the references will point you in the right direction if you have time to read i have posted them below i would go to local library or campus to research much better sources that are paid for that are unavailable to most of us hope the references help bud
hell id just try it cant hurt right? but it would deff be a prolonged study
