Registered clinical trials

Studies registered on ClinicalTrials.gov that list GHRP-6 as an intervention. Studies that only measure the molecule as a biomarker, or use it only as a comparator or background arm for another drug, are excluded. A registration describes a planned or completed protocol; it does not report a result. Active studies are listed first.

No registered study naming this compound was matched. This is a documented gap in registry coverage, not proof that no study exists.

Human intervention studies

Selected studies in which participants received GHRP-6, with their indexed or reviewed study type. Check the original article for the formulation, population and controls. Studies that only measured the molecule, or used it as a comparator, are listed separately below and are not counted as intervention studies.

Preclinical research, reviews & other publications

Animal studies, laboratory experiments, reviews and other indexed papers answer different questions. A review is secondary evidence; a case report does not estimate how often an outcome occurs.
