Ipamorelin Australia: Buy Ipamorelin Peptide Online

Shop Ipamorelin as a 10 mg Vial With Full Lot Data

Order ipamorelin to isolate the ghrelin route of growth hormone release without the hormonal noise older secretagogues bring. It is one of the best selling compounds in our growth hormone range, and each lot is documented online before you buy.

What Is Ipamorelin?

Ipamorelin is a lab-made peptide of five amino acids that imitates ghrelin, the so-called hunger hormone, at one receptor, prompting pituitary cells to release a burst of their own growth hormone. It contains no growth hormone and cannot stand in for it. Every effect described in the literature runs through cells that already make the hormone, and that is the first thing to get right when choosing a model.

How ipamorelin works in research models

Its target, GHS-R1a, is a G protein coupled receptor found on somatotroph cells in the anterior pituitary and on neurons in the hypothalamus. Once an agonist binds, the receptor signals through Gq, calcium rises inside the cell, and stored granules of growth hormone are released. Natural ghrelin is a 28-residue peptide made mostly in the stomach, and it only activates the receptor when an octanoyl fatty acid is attached to its third residue. The ipamorelin peptide needs no such add-on. Five residues, an amide cap and a few mirror-image building blocks are enough to fit the same pocket.

The history runs in the opposite order to what most people assume. A Merck team cloned the receptor in 1996, using synthetic secretagogues as bait, and ipamorelin was already being characterised before a Japanese group isolated ghrelin from rat stomach in 1999. For a few years, compounds like this one were keys to a lock whose natural key nobody had found.

The cleanest human pharmacology comes from a 1999 paper in Pharmaceutical Research by Gobburu and colleagues, who gave intravenous infusions to healthy men at five rates, with eight men at each rate. Plasma levels scaled in proportion to the amount infused, the terminal half-life was about 2 hours, and growth hormone appeared as one discrete episode that peaked roughly 40 minutes in. There was no second wave.

That profile leads to our practical view on what is ipamorelin useful for at the bench: it is a timing tool more than anything. A design that samples at 15-minute intervals across the first 90 minutes will capture the whole curve, while a lone reading at the four-hour mark usually shows nothing at all. The other trap is the model itself. Hypophysectomised animals and cell lines without functioning somatotrophs give a flat result, because there is no stored hormone for the receptor to release. Our full guide to the published ipamorelin trials sets out what the clinical studies measured.

Buy Ipamorelin Peptide Online in Australia, the Selective GHRP

Ipamorelin was described in 1998 by researchers at Novo Nordisk in Denmark, who presented it as the first selective growth hormone secretagogue. It descends from the GHRP family pioneered by Cyril Bowers, alongside GHRP-2 and GHRP-6, but was designed to release growth hormone without driving the adrenal axis. In the original rat pituitary cell and pig studies it matched GHRP-6 on growth hormone while leaving ACTH and cortisol largely flat.

Buy it for that selectivity. It makes the pentapeptide a clean probe for growth hormone pulsatility, cooperation between ghrelin and GHRH signalling, and IGF-1 feedback, and some groups use it in rodent gut motility work. Because it adds almost nothing to the adrenal or prolactin readouts, a study can attribute a change in growth hormone output to the ghrelin receptor with more confidence than an older GHRP would allow, which is why reviewers often expect it as the reference compound in secretagogue comparisons. It is a research reagent, not a medicine, and has no TGA approval. The full family sits in our growth hormone peptides category.

Is Ipamorelin Legal in Australia? The Vial and Its Status

Open the box and you find one clear glass vial holding 10 mg of ipamorelin as a dry white cake, nothing else blended in and no liquid supplied. The molecule came out of Novo Nordisk's secretagogue chemistry in Denmark in the 1990s, and its time as a drug candidate was brief. Helsinn later licensed it and ran an intravenous phase 2 trial in post-operative ileus after bowel surgery; the paper, published in 2014, reported that the main endpoint missed statistical significance, and development faded. No regulator anywhere has approved a medicine built on it.

So is ipamorelin legal in Australia? It is controlled rather than unknown. As of October 2026, the current Poisons Standard (the June 2026 instrument) names ipamorelin in Schedule 4, the prescription-only schedule, and again in Appendix D, clause 5, the list of poisons that are illegal to possess without authority. The TGA's scheduling committee reviewed growth hormone releasing peptides as a group in 2014 and 2015, which is why ipamorelin, CJC-1295, GHRP-2 and GHRP-6 share those controls today. With no approved product in existence, nothing containing ipamorelin is registered on the ARTG, so there is no pharmacy version and the compound only circulates here as a research chemical.

Sport adds a second layer. WADA's 2026 Prohibited List names ipamorelin among the growth hormone secretagogues in class S2, banned in and out of competition, and Sport Integrity Australia enforces that list for Australian athletes.

For laboratories wanting ipamorelin for sale from a local source, AminoBlend holds it in Australian stock as a research reagent, sold only to adults aged 18 and over, for in vitro work and never for human or veterinary use. Groups that buy ipamorelin in Australia to contrast it with a GHRH receptor agonist often add the sermorelin acetate vial as a second reference.

Order Ipamorelin in a 10 mg Format at a Low Cost per mg

Shop one size, the 10 mg vial at $59, which is $5.90 per mg and the lowest per-milligram cost in our growth hormone range. At roughly 712 g/mol, the peptide packs many more molecules into each milligram than a 29-residue GHRH analogue, so one vial carries most cell or rodent study plans.

Order several vials together and they stay on a single lot wherever stock allows. Open one at a time and leave the rest sealed in the freezer, all covered by the same certificate. Only buyers who are at least 18 can place an order, and each one declares a laboratory purpose before paying.

Shop the Ipamorelin Peptide With Structure and Purity on File

Three of its five residues are non-natural, namely aminoisobutyric acid at the N-terminus, D-2-naphthylalanine and D-phenylalanine. Together with the C-terminal amide, they shield the chain from proteases and give it a distinctive mass. On the certificate, look for a measured value near 711.9 g/mol, then read the HPLC trace and the purity number reported for that lot.

A badge on a website says nothing about the vial on your bench, while a lot-matched report does. Buy with that report in hand, filed in our COA library under the code printed on your label, so you can compare our data line by line with any other source before ordering.

Order Ipamorelin Online From Anywhere in Australia and Store It

Ipamorelin is ordered online from this page and shipped from our Australian warehouse to labs in every state and territory, with no shop or pickup point involved. A lab sourcing research peptides in Melbourne orders from the same stock as one in Broome. Order before 3pm on a business day and the vial goes out the same afternoon, tracked all the way, with timeframes listed under delivery information.

Buy bacteriostatic water in the same cart, since the powder dissolves very easily and preparation is quick. Let the vial warm to room temperature and run the liquid down the glass before a gentle swirl. One millilitre in the 10 mg vial gives 10 mg/mL, and 2 mL halves that to 5 mg/mL, while the reconstitution calculator handles every other volume.

Keep sealed ipamorelin vials frozen at -20 °C. The solution belongs at 2 to 8 °C, split into aliquots for a long series rather than frozen and thawed again.

Other Names for Ipamorelin

The compound also appears as ipamorelin acetate, its usual salt form, and under the development code NNC 26-0161. Chemists write it as Aib-His-D-2Nal-D-Phe-Lys-NH2 or H-Aib-His-D-2-Nal-D-Phe-Lys-NH2, and all of these refer to CAS 170851-70-4.

The receptor vocabulary is worth knowing. GHS-R1a, the growth hormone secretagogue receptor, is the same receptor ghrelin activates, and the compound is classed as a GHRP, a GH secretagogue and a ghrelin mimetic. Older papers group it with the growth hormone releasing peptides of the 1980s and 1990s, while newer reviews file it under ghrelin receptor agonists, and the vial on your bench is the same molecule in both cases.

Buy CJC-1295 Ipamorelin as a Pair or a Blend

They are partners rather than rivals. Ipamorelin acts on the ghrelin receptor, while CJC-1295 No DAC, $79 for 10 mg, is a GHRH analogue acting on the GHRH receptor. Studies of synergy between the two pathways usually need both, as separate vials so each amount can be set on its own, which makes it the best peptide to stack with ipamorelin in most designs.

Shop the CJC-1295 and Ipamorelin Blend when a protocol is fixed at equal amounts, as it holds 5 mg of each for $65. Buy the single vial whenever the ghrelin arm must be studied without a GHRH input. If the GHRH partner is still undecided, the CJC-1295 DAC vs No DAC guide explains the difference.
