Buy GHRP-2 Peptide in Australia
Buy GHRP-2 in Australia from Macropus Peptides in 5mg and 10mg research vials. GHRP-2, also known as pralmorelin, is a synthetic six amino acid growth hormone releasing peptide that activates the ghrelin receptor on the pituitary, and it is generally reported as the most potent growth hormone releaser of the original GHRP series. It is supplied as the acetate salt, freeze-dried in sealed vials labelled with compound, strength, lot number and storage temperature, and a certificate of analysis is available for every lot. Both sizes are quoted on request: send the size and quantity and we confirm the price before you order. Laboratories often pair it with a GHRH analogue such as Sermorelin or CJC-1295 no DAC, and GHRP-6 is stocked for direct comparison. Add bacteriostatic water and the parcel ships from inside Australia to any address in the country. GHRP-2 is for in-vitro laboratory research only, sold to adults 18 and over, and not for human or veterinary use.

Buy GHRP-2 Australia: 5mg and 10mg Vials
Our stock of this high-potency secretagogue is held as 5mg and 10mg vials, filled to a common specification with every batch released separately. It is the high-potency member of the GHRP family and a standard tool for ghrelin receptor and pituitary synergy studies. Both vials are currently priced by quote, so the first step is a short enquiry.
What is GHRP-2
GHRP-2 stands for growth hormone releasing peptide 2. It is a hexapeptide: D-alanine, D-2-naphthylalanine, alanine, tryptophan, D-phenylalanine and lysine, with an amide at the end. Compared with GHRP-6, it replaces the D-tryptophan with the bulkier D-2-naphthylalanine and the first histidine with D-alanine. Under the name pralmorelin it was approved in Japan as a diagnostic agent for testing pituitary growth hormone reserve, but it has no registration in Australia and is supplied here for research. Like the rest of its family, it was designed by chemists working forward from small synthetic peptides, and it was in wide laboratory use before anyone had found the receptor it acts on or the stomach hormone that normally occupies that receptor. That history explains why so much of the early secretagogue literature uses it as a reference compound.
GHRP 2 acetate peptide: how it works in research
The peptide is an agonist of the growth hormone secretagogue receptor, the receptor whose natural ligand is ghrelin. Found on growth hormone cells and in hypothalamic neurons, the receptor signals via phospholipase C and intracellular calcium. Because this route is separate from the cyclic AMP route used by the GHRH receptor, combining it with a GHRH analogue releases more growth hormone than either compound alone, and that synergy is one of the main things researchers use it to study. It also raises cortisol and prolactin somewhat, which is why selective alternatives are used when those hormones must stay flat. The acetate is simply the counter-ion left from purification; it does not change the peptide. Once dissolved, the solution is best kept in a refrigerator rather than a freezer, drawn from with clean technique, and used within the window your own stability checks support, since peptides in solution keep far less well than the dry powder.
GHRP-2 research: what the studies show
The receptor it acts on was cloned and described in Science in 1996, explaining how the synthetic GHRPs worked years after they were first made. The natural ligand, ghrelin, was identified in Nature in 1999. In 2007 the European Journal of Endocrinology published an evaluation of a simple stimulation test built on the peptide for adult growth hormone deficiency, measuring how well the growth hormone response distinguished deficient from normal pituitary function. The papers are summarised in our GHRP-2 research studies library.

The acetate salt comes as a dry lyophilised cake in a crimp-capped glass vial. Printed details on each label: peptide name, mass, lot and storage temperature. Tell us the lot and we return its certificate of analysis. Sealed stock is happiest in a -20 °C freezer, kept dark.
GHRP 2 price in Australia
| Option | Price |
|---|---|
| GHRP-2 5mg | Price to confirm |
| GHRP-2 10mg | Price to confirm |
Neither vial is listed at a checkout price yet, so both are quoted. The 10mg vial holds twice the 5mg amount and is the better value whenever its quote is below double the smaller one, which larger fills normally are.
GHRP 2 10mg: where to buy in Australia
For a full synergy series, buy the 10mg size so the ghrelin-side arm never changes lot. Its stock strengths: 5 mg per mL after 2 mL of water, 2 mg per mL after 5 mL.
GHRP 2 5mg for pilot studies
The 5mg vial suits a first experiment or a short comparison against GHRP-6. Its stock runs 2.5 mg per mL with 2 mL of water, or 1 mg per mL if the volume is 5 mL.
GHRP 2 vs GHRP 6: the difference between them
Both are hexapeptide ghrelin receptor agonists and both run through decades of secretagogue research. Head-to-head work generally reports it as the stronger growth hormone releaser, while GHRP-6 more closely copies ghrelin's wider actions, including its effect on appetite pathways in the hypothalamus. Choose it when the endpoint is pituitary output, and GHRP-6 when the study concerns the ghrelin system more broadly. Hexarelin adds CD36 binding, and Ipamorelin gives the narrowest hormone profile of the group.

GHRP-2 calculator: stock strength for 5mg and 10mg vials
Every figure is milligrams over millilitres. The 5mg vial in 2 mL makes a 2.5 mg per mL stock, and in 2.5 mL a 2 mg per mL stock. A 10mg vial taken into 2 mL of water reads 5 mg per mL, and into 4 mL half of that. Add bacteriostatic water so the diluent arrives with the vials.
Is GHRP 2 available in Australia
GHRP 2 Australia supply is limited to research: in-vitro bench work is the sole purpose we accept. With no ARTG registration, it stays out of reach of any human or animal use. The TGA includes growth hormone releasing peptides in the Poisons Standard, and it is the buyer's job to confirm how the current wording affects their organisation.
GHRP-2 for sale Australia wide
Our Australian team packs and posts orders to research addresses nationwide, from the capitals to regional centres. The rest of the growth hormone research range includes Tesamorelin, Ipamorelin and the CJC-1295 analogues.
