I came here ready to say there wasn’t any evidence that links HGH use with an increase in red blood cell production…
HOWEVER, I asked chat gpt just to be sure and it looks like increased IGF1 could be linked to higher hemoglobin. Very interesting considering my hemoglobin is always high and I also always have high IGF1 levels (it was 313 when I wasn’t on any HGH at all).
Chat gpt says:
“There is some evidence to suggest that higher levels of insulin-like growth factor 1 (IGF-1) may have a positive association with hemoglobin levels. IGF-1 is a hormone that is produced in response to the secretion of growth hormone (GH) by the pituitary gland. It plays a role in growth, development, and various metabolic processes.
IGF-1 has been found to have stimulatory effects on erythropoiesis, which is the process of red blood cell production. It can enhance the production and maturation of red blood cells in the bone marrow, leading to an increase in hemoglobin levels.
Several studies have observed a positive correlation between IGF-1 levels and hemoglobin levels. For example, a study published in the Journal of Clinical Endocrinology and Metabolism in 2012 found that higher IGF-1 levels were associated with higher hemoglobin levels in healthy adults. Another study published in The Journal of Clinical Investigation in 2005 reported similar findings.”
