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 in the published research.

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.
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.

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 synthetic hexapeptide growth hormone secretagogue, studied for producing the strongest GH pulse in its receptor class and for fast desensitization with continuous use.
Hexarelin vs Ipamorelin, what's the difference?
Both act on the same ghrelin receptor family, but Hexarelin produces a stronger GH response with a less favorable side effect profile, while Ipamorelin is studied as more selective, with minimal effect on cortisol and prolactin. Compare Ipamorelin pricing.
Does Hexarelin research include dosage information?
PepLookup doesn't publish dosing guidance for any compound. The Evidence section on this page cites the actual published studies, the appropriate source for research protocol design.
Does PepLookup sell Hexarelin?
No. PepLookup is a comparison tool. We list publicly published prices from suppliers so they can be compared side by side. Every order is placed on the supplier's own site.
What forms does Hexarelin come in?
