Nonetheless, is it still not known as GH Gut?
Please could you link to some research that backs up what you've just said above, because everything I've read has indicated that it's not clear what causes GH gut - whether it's the GH, slim, igf or a combination of all of them. As far as I'm aware there have been no tests done which provide a conclusive answer. I am happy to be proven wrong if you have the information available however.
In particular, the fact that there have been cases cases of researchers claiming that "gh gut" has been experience by those on GH ALONE due to the growth of internal organs and connective tissue makes me really question whether it's just slin and igf that causes the gut.
