Repeated dosing study, 1996
A trial in six subjects found hexarelin and GHRH synergistic on first administration, but the synergy was lost when dosing was repeated over time. Reported in the cited paper.

Growth Hormone
Hexarelin
Hexarelin is a synthetic hexapeptide growth hormone secretagogue that produces the strongest pulse in its class. It also desensitises fastest, with the response falling within two to four weeks of continuous use, so protocols are cycled rather than run continuously.

Overview
What is Hexarelin?
Hexarelin is a synthetic hexapeptide growth hormone secretagogue that produces the strongest pulse in its class. It also desensitises fastest, with the response falling within two to four weeks of continuous use, so protocols are cycled rather than run continuously.

What the research reports
Reported benefits of Hexarelin
Outcomes described across the published Hexarelin literature and ongoing study. Read each as research context rather than a promised personal result.
- 01
Strongest GH pulse in class
Produces a larger growth hormone response than other peptides in the ghrelin receptor family, which is its defining pharmacological characteristic within the class.
- 02
Pituitary reserve testing
A 1999 cohort found the hexarelin test reliable for screening growth hormone deficiency, though unreliable for ACTH and cortisol reserve. Reported in research settings.
- 03
Cushing's differentiation
A 2000 trial reported the hexarelin test effectively separated Cushing's disease from alcohol induced pseudo-Cushing's syndrome. Reported in research settings.
- 04
Cardiac research interest
A separate research line explores cardioprotective effects through CD36 signalling that appear independent of growth hormone release. Reported in research settings.
- 05
Metabolic pathway research
Work describes CD36 and PPAR gamma activation linked to insulin resistance and lipid handling in metabolic disorder models. Reported in research settings.
Dosage and protocol
How Hexarelin is typically studied
Protocols use 100 to 200 mcg two or three times daily, cycled 2 to 4 weeks on and 4 weeks off because of rapid desensitisation. Figures describe study protocols, not a personal regimen.
- Route
- Subcutaneous injection
- Example range
- 100-200 mcg
- Frequency
- Two to three times daily
- Timing
- Empty stomach, 30 min before meals. Cycling is required by design.
Clinical evidence
Clinical evidence for Hexarelin
The published Hexarelin record, labeled by strength so you can see what is settled and what is still emerging.
Elderly response trial, 1994
A trial in 29 elderly subjects reported that adding GHRH or arginine restored the blunted growth hormone response seen with hexarelin alone. Reported in the cited paper.
SourcePituitary reserve test, 1999
A cohort of 19 patients with pituitary disease found the hexarelin test reliable for screening growth hormone deficiency but not for ACTH or cortisol reserve. Reported in the cited paper.
SourceInteractions
How Hexarelin pairs with other peptides
- GHRP-2 peptide
- Both act on the ghrelin receptor, so combining duplicates one target and compounds cortisol effects.
- CJC-1295 blend
- Synergistic on first dosing, though published work shows the synergy fades with repeated administration.
- Ipamorelin
- Same receptor family with a far lower side effect profile, so combining offers little practical gain.
- MK-677 oral use
- Stacking secretagogues raises IGF-1 and insulin resistance risk while desensitisation still applies.
Questions
Frequently asked questions.
What is Hexarelin?
Hexarelin is a peptide compound used in research settings. It is commonly studied for its role in growth hormone, and many researchers compare supplier quality, purity, and testing data before purchasing.
What are the research benefits of Hexarelin?
Hexarelin is often evaluated for its potential influence on signaling pathways, recovery support, and targeted research applications. Research interest varies by peptide, formulation, and study design, so buyers typically review purity, dose, and independent lab verification before choosing a source.
How does Hexarelin work?
Like other research peptides, Hexarelin is typically studied for how it interacts with specific biological pathways and receptor systems. In practice, the way it is formulated, dosed, and tested matters as much as the compound itself, which is why verified suppliers and transparent COAs are important.
Is Hexarelin for research use only?
Yes, products like Hexarelin are generally intended for research, laboratory, or educational use and are not marketed as approved human therapeutics. Always follow local laws, lab safety practices, and institutional requirements before handling or studying any peptide.
What should I look for before buying Hexarelin?
Key checks include verified COA data, peptide form and concentration, supplier reputation, stock status, and cost per mg. Comparing pricing and testing records side-by-side helps reduce the risk of buying an under-tested or misrepresented product.
