hexarelin vs ghrp

[ThorSF]

O.K. , so im definately a newbie and i am currently in over my head. I guess a few stats may help a bit.
I am 40 years old 5'10.5" 210 lbs. I shud around 190 (or used to be... lol). I am looking to add a little mass maybe 15 to 20 sustainable pounds and lean out and help this body feel better.

I'm thinking hgh might be the way to go. My research so far on this site has found these products. I don't know anything about them really.

I guess one helps your body produce your own? which might sound to be the better way, but then will your body ever start to produce eneough on its own without stimulation?
I have read that it can harm your joints but also have read it helps in healing them?
I am looking for a little advice to hopefully point me in the right direction. Hopefully I can answer alot of my questions by the time I figure out where to source it so I know what I need to buy along with all the accessories.
Thanks for all your help in advance,
thor
