Hexarelin: research, prices and suppliers

A synthetic hexapeptide from the growth hormone-releasing peptide class, studied in early clinical research on growth hormone secretion.

Sources and dates are stated with individual entries. This new presentation is not a complete re-investigation of all data.

Hexarelin is a synthetic hexapeptide from the GHRP (growth hormone releasing peptide) class, first pharmacologically described in 1994. It has been studied in clinical trials on growth hormone secretion in children, adults, and older adults, and separately in preclinical research on cardiac effects.

Evidence

In studies on newborn and adult rats, hexarelin triggered a pronounced and long-lasting growth hormone release, and was more effective than the related peptide GHRP-6 when given subcutaneously. Deghenghi R et al. 1994, Life Sciences, Bd. 54(18), S. 1321-1328, PMID 7910650
In a study of 60 people aged 5 to 81, the growth hormone response to hexarelin was compared across prepubertal and pubertal children, young adults, and older adults, with a markedly weaker response in prepubertal children and older participants. Arvat E et al. 1997, European Journal of Endocrinology, Bd. 137(6), PMID 9437229
In a study of 15 healthy men, hexarelin increased ACTH and cortisol, an effect that was enhanced by desmopressin (a vasopressin analog), suggesting vasopressin involvement in this side effect. Korbonits M et al. 1999, Journal of Clinical Endocrinology & Metabolism, Bd. 84(7), S. 2489-2495, PMID 10404825
In a rat model, hexarelin showed protective effects on the heart after ischemia-reperfusion that occurred independently of growth hormone activity and were attributed to direct binding to cardiac receptors. Locatelli V et al. 1999, Endocrinology, Bd. 140(9), S. 4024-4031, PMID 10465272

Frequently asked questions

Does hexarelin differ from ipamorelin

Yes. Both bind to the same ghrelin receptor, but hexarelin additionally showed a relevant release of ACTH and cortisol in studies, while ipamorelin is considered more selective for the growth hormone axis alone.

Was hexarelin studied in children

Hexarelin has been used in clinical studies on growth hormone secretion in children at different pubertal stages, within controlled research protocols and not as an approved medication.

Is hexarelin an approved medication

No. Hexarelin is not approved as a medication in the EU or the US and is offered exclusively as a research chemical, not for human use.

Questions about interpretation

What does the search “Hexarelin protocol” mean?

“Protocol” is often used to mean a regimen. This page explains research and documented listings. It contains no doses, cycles or instructions for human use. An online regimen is not scientifically validated simply because it is widely shared.
