Product Overview
Hexarelin 5 mg by Peptide Hubs
Hexarelin 5 mg is a lyophilized growth hormone secretagogue research product manufactured by Peptide Hubs and supplied as a 5 mg/vial powder in a 2 mL vial.
Hexarelin Injectable
Hexarelin 5 mg contains hexarelin, a synthetic hexapeptide that acts as a growth hormone secretagogue (GHS) and ghrelin receptor agonist . Hexarelin is structurally related to GHRP-6 and was developed as a more potent GH-releasing peptide. It is one of the most effective GH secretagogues in terms of the magnitude of GH release, though it is also associated with rapid desensitization compared to other GHRPs .
Hexarelin stimulates endogenous GH release through activation of the ghrelin receptor (GHS-R1a) in the pituitary and hypothalamus . It also has unique cardioprotective properties that appear to be independent of GH release, mediated through CD36 receptor binding . The peptide has been studied in clinical settings for diagnostic purposes, including assessment of GH deficiency and cardiac function .
Hexarelin is not FDA-approved for any human indication in the United States. In non-medical bodybuilding contexts, it is commonly referenced for GH release, though its rapid desensitization profile limits extended use. The FDA has documented serious adverse events including death associated with GHRP-6, a structurally related compound, and has raised concerns about the lack of characterization data for GHRP-related substances .

Formulation
Lyophilized Powder
Hexarelin 5 mg is supplied as a lyophilized (freeze-dried) powder in a 2 mL vial. Reconstitution with an appropriate solvent is required before use in research contexts.
Product Profile
Hexarelin Profile
Hexarelin is a synthetic hexapeptide with a molecular weight of approximately 887 Da and the amino acid sequence His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2 .
Ghrelin Receptor Agonist
Hexarelin belongs to the class of growth hormone secretagogues (GHS) that stimulate GH release through activation of the ghrelin receptor (GHS-R1a) . This mechanism is distinct from GHRH analogs such as CJC-1295, which act through the GHRH receptor. Hexarelin is considered one of the most potent GHRPs for GH release, but it also produces significant cortisol and prolactin elevation compared to more selective compounds like ipamorelin .
Unlike other GHRPs, hexarelin has been studied for cardioprotective effects that appear independent of GH release. Research has shown that hexarelin protects cardiac tissue from ischemia-reperfusion injury through CD36 receptor binding, suggesting a direct myocardial mechanism . This unique property has generated interest in research beyond GH secretion.
In non-medical bodybuilding contexts, hexarelin is commonly referenced for GH release, but its rapid desensitization profile is well documented. Repeated administration leads to diminishing GH response within days, which has implications for research protocols .
Defining Characteristic
Potent GH Release with Rapid Desensitization
Hexarelin is distinguished by its high potency for GH release and its unique cardioprotective properties, but it is also known for rapid desensitization compared to other GHRPs . This profile makes it distinct from ipamorelin and GHRP-2.
Hexarelin 5 mg vs Other Peptide Hubs Preparations
Peptide Hubs offers several growth hormone secretagogues for research. Within this lineup, Ipamorelin is a more selective GHRP that produces GH release with minimal effects on appetite and cortisol, and it does not exhibit the same rapid desensitization as hexarelin .
For research focused on GHRH receptor pathways rather than ghrelin receptor pathways, CJC-1295 No DAC represents a different mechanism of GH stimulation. GHRP-2 is another ghrelin receptor agonist with a somewhat different activity profile and less desensitization than hexarelin .

Dosage & Usage
Hexarelin 5 mg Dosage & Usage
The information below is provided for educational reference only. Hexarelin is not FDA-approved for any human use in the United States. Its use for any non-medical purpose falls outside approved indications, and no established human dosing regimen exists for bodybuilding or performance contexts .
Typical Dosage Ranges
Because hexarelin lacks FDA approval and published human dose-finding trials for non-diagnostic applications, there is no medically established dosage range for research or bodybuilding contexts. In non-medical research communities, reference ranges are derived from community convention. Commonly referenced ranges are 100–200 mcg per injection, administered 1–3 times daily .
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Standard research protocol (non-medical) | 100–200 mcg | 1–3 times daily |
| Combined with CJC-1295 (non-medical) | 100 mcg hexarelin + CJC | 1–2 times daily |
| Upper range (non-medical) | 200 mcg | Once daily |
Community protocols commonly reference dosing in a fasted state, typically before bed and/or post-workout to align with natural GH pulses. Due to hexarelin’s rapid desensitization, cycles are typically limited to 4–6 weeks.
Reconstitution & Handling
Hexarelin 5 mg is supplied as a lyophilized powder and requires reconstitution before use. A 5 mg vial reconstituted with 2 mL of solvent yields a concentration of 2.5 mg/mL (2,500 mcg/mL), meaning a 100 mcg dose would require drawing 0.04 mL (4 units on a U-100 insulin syringe).
Reconstituted solution should be stored refrigerated at 2–8°C and protected from light. Avoid repeated freeze-thaw cycles.
Stacking & Cycle Considerations
In non-medical bodybuilding contexts, hexarelin is sometimes combined with GHRH analogs such as CJC-1295 No DAC for potential synergistic GH release through parallel pathways . Cycle lengths are typically limited to 4–6 weeks due to desensitization, followed by a 4-week break.
For research comparing different ghrelin receptor agonists, Ipamorelin offers a more selective alternative with less desensitization and reduced cortisol/prolactin effects .
Important
Individual Response Varies
No human dose-response data for therapeutic outcomes exists for hexarelin in non-medical contexts. All dosage information is derived from community convention and should not be interpreted as medical guidance.
Safety & Information
Hexarelin Safety Information
Hexarelin is not FDA-approved for any human use in the United States. The FDA has documented serious adverse events including death associated with GHRP-6, a structurally related compound, and has raised concerns about the lack of characterization data for GHRP-related substances .
Important Safety Information
Hexarelin has not received FDA approval. The FDA’s 2023 review of peptide safety data documented serious adverse events including death associated with GHRP-6, a structurally related compound, and noted immunogenicity risk from impurities and aggregation .
As a peptide administered parenterally, hexarelin may pose immunogenicity risks. The FDA has raised concerns about the lack of characterization data for GHRP-related substances, including critical data on impurities, aggregates, and endotoxins .
Important
Non-Medical Use
Hexarelin is marketed as a research peptide, but it is not FDA-approved for any human indication. Non-medical use falls outside approved indications and carries documented serious risks associated with related compounds .
Potential Adverse Effects
Hexarelin is known to increase cortisol and prolactin levels alongside GH, unlike more selective GHRPs such as ipamorelin . This broader hormonal effect may be relevant in research contexts. Increased appetite is a documented effect of hexarelin, though less pronounced than with GHRP-6 .
Rapid desensitization to the GH-releasing effects of hexarelin is well documented, with diminishing response after repeated administration . Community discussions also mention potential water retention, joint stiffness, and numbness/tingling in extremities, though these reports are anecdotal.
Conditions Requiring Medical Evaluation
Given the documented serious adverse events associated with related compounds and absence of long-term safety data, any consideration of hexarelin use should involve consultation with a qualified healthcare professional. Individuals with a history of cancer or strong family history of malignancy should exercise particular caution due to theoretical mitogenic concerns with GH/IGF-1 signaling .
Monitoring During Use
No established monitoring protocol exists for non-medical hexarelin use. Clinicians evaluating patients using GH-related peptides should consider monitoring IGF-1 levels, blood glucose, and potential injection site reactions .
