Ipamorelin

Ipamorelin (CAS 170851-70-4, sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2) is a synthetic pentapeptide that selectively agonises GHS-R1a (ghrelin receptors) to stimulate pulsatile GH release. Research consistently distinguishes it from earlier GHRPs by its selectivity — GHRP-6 significantly elevates cortisol and appetite; GHRP-2 is more potent but raises cortisol; Ipamorelin produces robust GH pulses with negligible off-target hormone co-secretion. Downstream research areas include IGF-1 elevation, lipid metabolism, protein synthesis, recovery, and sleep quality. For research use only.

GHRP-6 (first generation) stimulates GH release but also significantly elevates cortisol, prolactin, and hunger — making it difficult to study isolated GH axis effects. GHRP-2 (second generation) is more potent for GH but still raises cortisol substantially. Ipamorelin (third generation) was specifically developed for receptor selectivity — it produces comparable GH output with a much cleaner hormonal profile. This makes Ipamorelin the preferred GHRP when researchers need isolated GH pulse data without confounding cortisol or prolactin variables. Not for human consumption — for research use only.

Ipamorelin and CJC-1295 trigger GH release via different receptor systems with no overlap. Ipamorelin is a GHRP — it mimics ghrelin and binds GHS-R1a to initiate GH pulses. CJC-1295 is a GHRH analogue — it binds GHRH receptors to amplify pulse amplitude and extend duration. Because they work on separate systems, using both produces synergistic GH output significantly greater than either alone. We offer this combination as the pre-blended CJC-1295 + Ipamorelin 10mg — Australia's most widely used GH peptide stack. Not for human consumption — for research use only.

Reconstitution: Draw 1–2mL of bacteriostatic water into a clean 31G insulin syringe. Inject slowly down the inside wall of the Ipamorelin vial. Gently swirl until fully dissolved. The solution should be clear and colourless. Common concentration: 1mL BAC water = 10mg/mL; 2mL = 5mg/mL. Storage: Lyophilised — store at −20°C for up to 24 months. Reconstituted — refrigerate at 2–8°C and use within 28 days. Protect from light. Our BAC Water 10mL and Insulin Needles 31G are available for a complete setup.

Ipamorelin is legal to purchase in Australia for legitimate laboratory research purposes. It is not currently listed as a scheduled substance under the Therapeutic Goods Act or Poisons Standard when sold for research use only. Purchasers must be 18+ and confirm research-only use. It is not TGA-approved for human consumption, therapeutic, or veterinary use. Our Ipamorelin 10mg is independently verified at 99.0% HPLC purity with full COA documentation.

Ipamorelin is studied as a selective agonist of the ghrelin/growth-hormone-secretagogue receptor (GHS-R) that, in research models, stimulates growth-hormone release with minimal effect on cortisol and prolactin — a selectivity that distinguishes it from earlier secretagogues. This profile is central to its research interest. Not for human consumption — for research use only.

GHRP-6 and GHRP-2 are earlier growth-hormone secretagogues that, in research models, can also raise cortisol, prolactin and appetite signals. Ipamorelin is studied as a more selective alternative with a cleaner GH-release profile. They are distinct research tools targeting overlapping but non-identical pathways. Not for human consumption — for research use only.

Ipamorelin is studied for stimulating growth-hormone release in a pulsatile pattern that research suggests resembles physiological secretion, as opposed to a sustained elevation. This pulsatility is a frequently examined variable in growth-hormone-axis research models. Not for human consumption — for research use only.

Ipamorelin (a GHS-R agonist) and CJC-1295 (a GHRH analogue) act on two different receptors of the growth-hormone axis, so research examines them together to study potential complementary stimulation. This rationale underlies the combined CJC-1295/Ipamorelin product (/products/cjc-1295-ipamorelin). Not for human consumption — for research use only.

Ipamorelin is a selective growth-hormone-secretagogue (GHRP) research peptide, occasionally written Ipa, and is frequently paired with CJC-1295. For in-vitro research use only.
