What Is Hexarelin? A Research Primer
Hexarelin is a synthetic growth-hormone-releasing hexapeptide in the ghrelin-receptor agonist class. Sold for laboratory research use only.
Hexarelin (examorelin) is a synthetic hexapeptide growth-hormone secretagogue related to GHRP-6. It binds the ghrelin receptor and has also been characterised as binding the CD36 receptor. It is offered strictly as a research-use-only compound.
What makes hexarelin distinct
Hexarelin is a six-amino-acid peptide structurally related to GHRP-6 and GHRP-2. It is unusual in its family for binding a second receptor, CD36, in addition to the ghrelin receptor.
Research-use status
- Pharmacological class: ghrelin receptor agonist
- Published literature is mostly animal and cell work
- Sold for laboratory research use only; this page does not summarise effects or uses
COA and verification considerations
Because research compounds are unregulated, the certificate of analysis is the single most important thing to check. For Hexarelin, a trustworthy COA names the testing laboratory, reports HPLC purity (typically 99% or higher), confirms identity by mass spectrometry, and, for injectable-format material, includes endotoxin and sterility results. A batch or lot number that matches the product, a recent test date, and a working verification portal are strong positive signals.
What to check before buying
- Is a named third-party lab shown, not just a claim of testing?
- Does the COA lot number match the batch you are buying, with a recent date?
- Are purity and identity both reported, ideally with endotoxin and sterility?
- How does the vendor rank on our published, testing-led formula?
Frequently Asked Questions
How is hexarelin different from GHRP-6?
The two are structurally related hexapeptides with different sequences. Hexarelin also binds the CD36 receptor, and vendors list the two as separate products.
What should a hexarelin COA show?
A named third-party lab, HPLC purity (99%+), mass-spec identity confirmation, and endotoxin/sterility data for injectable research material.
Does affiliate status affect its ranking?
No. Vendor rank is determined only by our published methodology.
