Ipamorelin is a synthetic pentapeptide referenced as a selective agonist of the ghrelin / growth-hormone-secretagogue receptor (GHS-R1a) — a GHRP-class research peptide, and the cleanest standalone GHRP in the literature. Elite AU Peptides supplies it strictly for in-vitro and laboratory research use only — not for human or animal consumption, not a therapeutic good, and not TGA-approved. No muscle, performance, or human-use claim is made about it.

What research is Ipamorelin associated with?

Ipamorelin was introduced and characterised by Raun and colleagues (European Journal of Endocrinology, 1998) as the first selective growth-hormone secretagogue — with a selectivity profile that, unlike older GHRPs, did not significantly cross-activate the ACTH/cortisol axis in their research models. The receptor it agonises, GHS-R1a, was cloned and identified by Howard and colleagues (Science, 1996). It is studied in vitro as a receptor-research tool, not as a treatment.

How is Ipamorelin different from CJC-1295?

They act on different receptor classes: Ipamorelin is a GHRP (acting on the GHS-R1a / ghrelin receptor); CJC-1295 (no DAC) is a GHRH analogue (acting on the GHRH receptor). The canonical research pairing combines one of each — see the CJC-1295 + Ipamorelin research-stack guide.

Is Ipamorelin TGA-approved in Australia?

No. Ipamorelin is not TGA-approved and is not a therapeutic good. It is supplied strictly for in-vitro and laboratory research use only.

How is Ipamorelin tested and shipped?

Every batch is independently HPLC-tested by Janoshik Analytical before listing, with the certificate published on the product page and in the lab-reports library. Reconstitute with bacteriostatic water; store the powder at −20°C and, once reconstituted, at 2–8°C. Dispatched AU-domestic, free shipping over $100, same-day dispatch before 12pm AEST. Supplied strictly for laboratory research use only.

Ipamorelin in Australia. Ipamorelin is a synthetic pentapeptide referenced as a selective agonist of the ghrelin / growth-hormone-secretagogue receptor (GHS-R1a) — a GHRP-class research peptide, and the cleanest standalone GHRP in the literature. This guide is a research-reference summary for Australian researchers, framed strictly around receptor research. It makes no muscle, performance, or human-use claim.

What Ipamorelin is

Ipamorelin (sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂) is a synthetic pentapeptide in the “GHRP” (growth-hormone-releasing peptide) class, alongside GHRP-2, GHRP-6 and Hexarelin. What sets it apart in the research literature is selectivity — it is referenced as the “cleanest” standalone GHRP because of its receptor-selectivity profile.

The GHS-R1a receptor and the research behind it

Ipamorelin was introduced and characterised by Raun and colleagues (European Journal of Endocrinology, 1998) as the first selective growth-hormone secretagogue: in their research models it released growth hormone with a potency comparable to GHRH while, unlike older GHRPs, not significantly cross-activating the ACTH/cortisol axis — the selectivity profile that makes it the “cleanest” standalone GHRP. The receptor it agonises, the G-protein-coupled growth-hormone-secretagogue receptor (GHS-R1a), was cloned and identified by Howard and colleagues (Science, 1996). It is studied in vitro as a receptor-research tool, not as a treatment.

Ipamorelin and CJC-1295: the canonical pairing

In research models Ipamorelin is most frequently studied alongside a GHRH-analogue such as CJC-1295 (no DAC) — the canonical research pairing combines one GHRH and one GHRP because the two receptor classes act on distinct, convergent points of the same somatotrophic-axis research model. See the CJC-1295 GHRH guide, the stack guide for the co-lyophilised pairing, and the growth-hormone research peptides pillar for the wider category.

Not framed for muscle or performance — and compliance

Ipamorelin is framed strictly around receptor and pathway research. Elite AU Peptides makes no muscle, performance, anabolic, or human-use claim about it. Every batch is independently HPLC-tested by Janoshik before listing, with the certificate on the product page and in the lab-reports library. Ipamorelin is not TGA-approved and is not a therapeutic good — supplied strictly for in-vitro and laboratory research use only.
