Hexarelin (5mg) Research Peptide: A Potent and Stable GHRP for Growth Hormone & Cardioprotection Studies
If your research investigates growth hormone (GH) secretion, cardiovascular protection, or neuroprotection, Hexarelin (5mg) research peptide offers a precisely defined and well-characterised synthetic tool. Hexarelin (also known as Examorelin) is a synthetic hexapeptide that belongs to the growth hormone-releasing peptide (GHRP) class. As a potent agonist of the growth hormone secretagogue receptor (GHSR-1a), it mimics the action of the natural hormone ghrelin to stimulate the release of growth hormone from the pituitary gland. However, unlike many other GHRPs, Hexarelin is distinguished by its enhanced metabolic stability, oral bioavailability, and unique ability to exert direct cardioprotective effects independent of GH release. This makes Hexarelin (5mg) research peptide a valuable tool for laboratories investigating endocrinology, cardiovascular biology, and neuroprotection.
At Wuhan Top Miracle Peptides, we supply high‑purity Hexarelin (5mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to ≥98% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into GH regulation, cardioprotection, and neuroprotection begin with uncompromising quality.
What Is Hexarelin and How Does It Work?
To fully appreciate the research potential of Hexarelin (5mg) research peptide, it is essential to understand its biochemical design, enhanced stability, and the distinct mechanisms by which it exerts its effects.
The Synthetic Hexapeptide
Hexarelin is a synthetic hexapeptide (six amino acids) with the sequence H-His-D-2-Methyl-Trp-Ala-Trp-D-Phe-Lys-NH₂. Its molecular formula is C₄₇H₅₈N₁₂O₆, and its molecular weight is approximately 887 Da It has a CAS number of 140703-51-1.
The peptide incorporates two D-amino acids (D-2-methyltryptophan and D-phenylalanine), which confer enhanced resistance to enzymatic degradation compared to other GHRPs like GHRP-6. This structural modification results in a longer duration of action and the ability to be administered via multiple routes, including oral, intranasal, and subcutaneous.
Mechanism of Action: Dual-Pathway Signalling
The biological activity of Hexarelin (5mg) research peptide is mediated through two distinct but complementary pathways:
1. GH-Releasing Activity via GHSR-1a
Hexarelin acts as a potent agonist of the growth hormone secretagogue receptor (GHSR-1a), a G-protein-coupled receptor expressed in the hypothalamus and pituitary. By binding to this receptor, Hexarelin stimulates the synthesis and pulsatile release of growth hormone from the anterior pituitary. In comparative studies, Hexarelin has demonstrated stronger GH-releasing activity than GHRH and is slightly more effective than GHRP-6. Moreover, it shares a synergistic effect with GHRH when administered together.
2. GH-Independent Cardioprotective Actions via GHSR and CD36
Beyond its endocrine effects, Hexarelin exerts direct, GH-independent actions on the heart and blood vessels. It binds to both GHSR-1a and the non-GHSR receptor CD36 in cardiac tissue. Activation of these receptors triggers protective signalling cascades that:
-
Inhibit apoptosis (programmed cell death) in cardiac and skeletal muscle
-
Reduce oxidative stress and inflammation
-
Improve cardiac systolic function and reduce malondialdehyde production
-
Protect cardiomyocytes from ischemia/reperfusion injury
Research Note: Enhanced Stability and Bioavailability
When compared with ghrelin, Hexarelin is chemically more stable and functionally more potent. This stability allows for research applications that are not feasible with the unstable natural peptide ghrelin, including oral and intranasal administration.

Reconstitution & Handling Protocol for Hexarelin (5mg)
Proper reconstitution of Hexarelin (5mg) research peptide is critical for maintaining its structural integrity and biological activity.
Step 1 – Preparation
-
Bring the sealed Hexarelin vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.
-
Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.
Step 2 – Vial Sanitisation
-
Wipe the rubber stopper of the Hexarelin vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.
Step 3 – Reconstitution
-
Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 5 mg per 0.5 mL of diluent, yielding a 10 mg/mL stock solution.
-
Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.
-
Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.
Step 4 – Aliquoting & Storage
-
Immediately after dissolution, aliquot the reconstituted Hexarelin into single‑use sterile vials.
-
Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles, as peptides are susceptible to degradation.
-
Once thawed, store at 2‑8°C and use within 7 days.
