Yes. There has been study on this subject.
Role of growth hormone (GH) in liver regeneration.
That is interesting. I would think that would have to be closely monitored by a doctor though. There are many therapies that can be helpful like glutathione therapy for instance...But GH therapy...I guess that might be the best thing actually. It is one of the options that maybe you could discuss with your doctor should you have issues with your liver.
It is good to know that the affects are positive and even regeneration. I do think this is something that could help so many who are suffering from liver issues. It is a shame that peptides are not accepted by mainstream physicians because so many could benefit their treatment.
