I would NOT want to see these peptides used orally. They are meant to be the response to grhelins released in response to changes in energy status within the gut. They are not meant to be absorbed and taken up in the gut. This is my opinion (take as such).
I would NOT recommend using hexarelin, it fucks up sleep patterns. Sleep is essential for proper induction and utilization of growth factors. This is fact, verfieid in the biomedical literature (I have cited it elsewhere on this forum).
I withhold comment about ghrp-6. I have some reservations; I would need to see evidence that it can applied in a pulsate delivery, as normally occurs. The receptors it binds to are not meant to be hit for many hours with this peptide.
