can i run Hexarlin in a sust/deca cycle?

im totally new to peptides and have never done them. I know i was approved at a special doctor for HGH but my insurance wouldnt cover it and thats where that ended! But a good source has come open to me for peptides and i got 3 bottles of Hexerelin that is labeled, weight 2ml vial. I could get several others but read good things about Hex. Im just started a sust/deca cycle and was wondering if i could incorporate the hex into it somehow to help my stomach inflammation problems and help with gains. I have read up on peps but theres so much out there about this and so many different views, I just figured you guys alwasy have good answers and i trust you!thanks
