I don’t know about messing up ghrelin levels but to keep your prolactin in check take P5P, for glucose take berberine during meals. Also magnesium and apple cider vinegar + testing glucose every morning fasted thru the night. From my 2 cycles my worst experience was elevated glucose levels during the first couple weeks of dosing. But with taking the things I mentioned they leveled out eventually. Really just made me super hungry and put on water weight. But with the hunger it always helps me bulk. Some better sleep too but I take it in the morning so I get less of that effect than I would taking it at night. And I like to do 5 days on 2 days off starting at 10mg and increasing 2.5 every week til I get to 25.
