There are not too many studies on long term AGHD(adult growth-hormone deficiency) a term you will hear more about in the next few years as they release long acting gh. I myself, would just stop and do what I normally do: get bloodwork, fix anything that is wrong on bloods. I would e careful as gh helps protect the joints/muscles producing extra collagen in the body. It may cause some issues with loss of strength, increased pain post workout, etc. Of course stimulating the pituitary gland by just powerlifting, high aminos , or secretogogues Mk677, sermorelin, -morelins could be used safely w/o any bad sides like acromegaly. I am wondering if you used thyroid or insulin or metformin during your long term use ? If not, your B/G levels would definitely contribute to a gut or distended belly (like you see in diabetics that don’t diet correctly). Just get bloods, keep an eye on things. I like using a waist trainer, watching sugar intake and a lot of cardio. I have seen distention reversed in BB before.
