Quick answers

What is Hexarelin and what is it used for in research?
Hexarelin is classified within the GH Secretagogue group. Hexapeptide GHS. Stronger acute GH-release profile than ipamorelin but with greater cortisol/prolactin impact. Research applications focus on the pathways outlined below. All references on this page describe published research only, Hexarelin is supplied for in-vitro and laboratory use, not for human consumption.
How does Hexarelin work?
Primary mechanism: Potent ghrelin-receptor agonist; strong acute GH release. Downstream effects depend on dose, timing, and the biological system under investigation. Receptor binding and post-receptor signalling for Hexarelin remain areas of active study, and several proposed effects are supported only by preclinical data.
What is the typical Hexarelin research dose?
Published research protocols for Hexarelin describe per-dose ranges of 100 mcg × 2–3 / day, with a weekly total near 2–4 mg, administered 2–3× daily sc. Typical cycle: 4–8 weeks. These ranges reflect the literature and are not dosing recommendations for any individual.
Where can I buy Hexarelin in Thailand?
Hexarelin is supplied by Thailand Peptides, a Bangkok-based research-peptide supplier. Orders are placed directly via WhatsApp to the Bangkok research desk, no cart, no account, no forms. Pricing and shipping are provided on request. Open a line with the research desk →
How fast can Hexarelin be delivered in Thailand?
Same-week delivery across Thailand is standard for orders confirmed within business hours (GMT+7, Monday–Saturday). Bangkok metro deliveries typically arrive within 1–3 business days; other provinces within 3–5. Regional Southeast Asia shipping is available on request.

What is Hexarelin?

Hexarelin is a research peptide in the GH Secretagogue class. Potent ghrelin-receptor agonist; strong acute GH release. It is studied at per-dose ranges of 100 mcg × 2–3 / day (2–4 mg weekly), administered 2–3× daily sc over cycles of 4–8 weeks. Supplied in Thailand by Thailand Peptides, Bangkok-based, research use only.

Hexapeptide GHS. Stronger acute GH-release profile than ipamorelin but with greater cortisol/prolactin impact.

Published and preclinical data are summarised below; dose ranges shown reflect protocols in the research literature and should be interpreted accordingly.

How does Hexarelin work?

Hexarelin is a synthetic hexapeptide GHS that activates both the ghrelin receptor (GHS-R1a) and CD36. It produces a strong acute GH response, typically higher peak than ipamorelin, but also elevates cortisol, prolactin, and ACTH to a greater degree, and chronic dosing shows GH-response attenuation (tachyphylaxis). This profile is why ipamorelin is usually preferred for sustained research protocols.

Receptor binding affinity and post-receptor signalling for Hexarelin remain areas of active investigation; several proposed effects within the GH Secretagogue class are currently supported only by in-vitro or rodent data, and should be interpreted accordingly.

Hexarelin pharmacokinetics

Half-life
Approximately 55–70 minutes after SC administration in clinical studies.
Bioavailability
Rapid SC absorption; acute GH peak typically within 15–30 minutes.
Route of administration
Subcutaneous injection; early studies also used IV and intranasal routes.
Metabolic clearance
Rapid proteolytic degradation with predominantly renal excretion of fragments.

Hexarelin dosage & protocol

Reference protocol for Hexarelin (research context only, drawn from published literature):

  • Per dose: 100 mcg × 2–3 / day
  • Weekly total: 2–4 mg
  • Frequency: 2–3× daily SC
  • Cycle: 4–8 weeks

Hexarelin injection & handling

Reconstitution
Typical research prep: 5 mg vial + 2 mL bacteriostatic water, yielding 2.5 mg/mL.
Storage
Lyophilised powder at −20 °C; reconstituted solution refrigerated and used within 2–4 weeks.
Sites used in the research literature
Subcutaneous abdomen; frequent dosing benefits from site rotation.

Handling notes reflect methods used in published research protocols, not medical dosing guidance.

Stacking Hexarelin

Commonly referenced pairing with Hexarelin: GHRH analog. Stacking rationale should be grounded in complementary mechanisms, not additive speculation; interactions at shared receptors or enzymatic pathways should be accounted for. Both compounds in a Hexarelin stack are supplied by Thailand Peptides on the same order via the Bangkok research desk.

Contraindications

Active malignancy. Additional caution is warranted in individuals with hepatic or renal impairment, endocrine disorders, or concurrent pharmacotherapy affecting the pathways described above.
