Quick answers

What is Ipamorelin and what is it used for in research?
Ipamorelin is classified within the GH Secretagogue group. Pentapeptide GHS. Acts on GHS-R1a without appreciable effect on cortisol, prolactin, or appetite at standard research doses. Research applications focus on the pathways outlined below. All references on this page describe published research only, Ipamorelin is supplied for in-vitro and laboratory use, not for human consumption.
How does Ipamorelin work?
Primary mechanism: Selective ghrelin-receptor agonist; GH-specific with minimal cortisol or prolactin effect. Downstream effects depend on dose, timing, and the biological system under investigation. Receptor binding and post-receptor signalling for Ipamorelin remain areas of active study, and several proposed effects are supported only by preclinical data.
What is the typical Ipamorelin research dose?
Published research protocols for Ipamorelin describe per-dose ranges of 200–300 mcg × 2–3 / day, with a weekly total near 4–6 mg, administered 2–3× daily sc. Typical cycle: 12 weeks on / 4 off. These ranges reflect the literature and are not dosing recommendations for any individual.
Where can I buy Ipamorelin in Thailand?
Ipamorelin 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 Ipamorelin 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 Ipamorelin?

Ipamorelin is a research peptide in the GH Secretagogue class. Selective ghrelin-receptor agonist; GH-specific with minimal cortisol or prolactin effect. It is studied at per-dose ranges of 200–300 mcg × 2–3 / day (4–6 mg weekly), administered 2–3× daily sc over cycles of 12 weeks on / 4 off. Supplied in Thailand by Thailand Peptides, Bangkok-based, research use only.

Pentapeptide GHS. Acts on GHS-R1a without appreciable effect on cortisol, prolactin, or appetite at standard research doses.

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

How does Ipamorelin work?

Ipamorelin is a selective agonist of the growth-hormone secretagogue receptor type 1a (GHS-R1a, the ghrelin receptor). It stimulates GH release with high specificity and, unlike earlier GHS peptides such as hexarelin or GHRP-6, without clinically meaningful elevations of cortisol, prolactin, or ACTH at research doses. This selectivity profile is the primary reason ipamorelin is the GHS of choice in contemporary research protocols.

Receptor binding affinity and post-receptor signalling for Ipamorelin 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.

Ipamorelin pharmacokinetics

Half-life
Approximately 2 hours after SC administration in healthy subjects.
Bioavailability
Rapid SC absorption with GH response peaking within ~30–60 minutes.
Route of administration
Subcutaneous injection, typically 2–3 times daily in research protocols to mimic physiological GH pulsatility.
Metabolic clearance
Proteolytic degradation; predominantly renal excretion of fragments.

Ipamorelin dosage & protocol

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

  • Per dose: 200–300 mcg × 2–3 / day
  • Weekly total: 4–6 mg
  • Frequency: 2–3× daily SC
  • Cycle: 12 weeks on / 4 off

Ipamorelin injection & handling

Reconstitution
Typical research prep: 5 mg vial + 2–3 mL bacteriostatic water, yielding ~1.67–2.5 mg/mL.
Storage
Lyophilised powder at −20 °C; reconstituted solution refrigerated and used within 4 weeks in published protocols.
Sites used in the research literature
Subcutaneous abdomen is the most common site; alternate sides to reduce local irritation.

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

Stacking Ipamorelin

Commonly referenced pairing with Ipamorelin: CJC-1295, Tesamorelin. 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 Ipamorelin 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.
