Just curious why you are using GH and ghrh's at the same time? How are the results you're getting? Maybe someone more knowledgeable should chime in on that one. As far mixing everything together, I'd say there is no problem. Personally I would separate my GHRH and GH several hours apart at least, but that's just me. To me it just seems like you would benefit more by having your levels elevated for a longer period of time.
