Hey,
Check out this thread. I know its about GHRP-6, but from the 2nd page onward Grunt76 and the gang talk about mixing it up with hex and get into dosages and combinations.

Basically, GHRP-6 and Hex are both hexapeptides and do work in a somewhat similar fashion. (there are some differences in action as well)...
Personally, I decided to go with CJC since it is long lasting GHRH. The benefit in my eyes is that you dose less frequently, instead of multi times per day like ghrp/hex (sure, some do once a day). Also, the biggie for me si that CJC does not spike Cortisol and Prolactin like the hexapeptides do. Hex and GHRP raise cort and prolactin along with GH, CJC does not. This was especially important to me since I wanted to run something through PCT. Dont need any more cort or prolactin there
Anyhow, My 2 cents...
Take Care
