We searched ClinicalTrials.gov, the US public registry of clinical studies, and found no registered interventional human study for Hexarelin.
That is not the same as saying it does nothing. It means nobody has formally tested it in people and registered the result. Absence of evidence is not evidence of absence — but it does mean any claim about what Hexarelin does in humans is not resting on registered human research.
