About Melanotan II
Melanotan II is studied at the melanocortin receptors, a family of five (MC1R to MC5R) that act as docking points on the surface of cells. The IUPHAR/BPS Guide to Pharmacology records it as a full agonist at the human MC1, MC3, MC4 and MC5 receptors, with no interaction listed at MC2. Agonist means it switches those receptors on rather than blocking them. MC1R is the receptor found on melanocytes, the pigment-producing cells, which is why most published work on this compound focuses on it.
The evidence on Melanotan II is thin and almost entirely preclinical. Its development as a medicine was stopped on safety grounds. Published work is in melanocortin receptor research, using cell culture and animal models. Australian Research Peptides supplies the vial as a laboratory reference material and draws no conclusions of its own from that research.
Melanotan II is a cyclic (ring-shaped) peptide of seven amino acids, built from positions 4 to 10 of alpha-MSH and closed into a ring by a lactam bridge. Its sequence is Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2. The free base is C50H69N15O9, with a molar mass of 1,024.2 and CAS number 121062-08-6. Australian Research Peptides leaves those figures out of the spec table, because the acetate salt that research peptides usually come as has a different formula and a different mass.
Two related compounds often get confused with Melanotan II. Melanotan I is afamelanotide, a straight-chain peptide of thirteen amino acids approved as a medicine by the EMA in 2014 and the FDA in 2019, and Australian Research Peptides does not stock it. PT-141 is bremelanotide, which differs only at the end of the ring, and Australian Research Peptides lists it separately. The popular claim that Melanotan I acts at one receptor and Melanotan II at several isn't what the Guide to Pharmacology shows: both are listed as full agonists at the same four receptor subtypes.
BAC water (bacteriostatic water) is also sold by Australian Research Peptides.

Quick answers
Melanotan II is supplied to laboratories and researchers in Australia by Australian Research Peptides, as a 10 mg vial at A$79.99, out of stock for now, with 99.877% HPLC purity on its Janoshik certificate (June 2026). Melanotan 2, MT-2, MT2 and MT II all lead to this one listing. No vial can be packed right now, and the 12pm Sydney time weekday cut-off applies again once stock arrives. Tracked delivery, Express or standard, reaches every state and territory, and the parcel starts its journey inside Australia.
Melanotan II is a cyclic peptide of seven amino acids and a non-selective melanocortin receptor agonist (it switches on several of those receptors), studied in melanocortin receptor research because MC1R is the receptor found on melanocytes (pigment cells). Other melanocortin receptors have been studied in cell culture and animal models. Australian Research Peptides supplies this material for laboratory work and draws no conclusions of its own from that research.
Yes, Melanotan II 10 mg was analysed on 19 June 2026 by Janoshik, an independent laboratory commissioned by the manufacturer, which recorded 99.877% purity by HPLC. High-performance liquid chromatography (HPLC) measures how much of the sample is the peptide, and mass spectrometry then confirms the molecule really is Melanotan II and not a look-alike powder. The identity check matters most for Melanotan II, because it, Melanotan I and PT-141 have names close enough to be mixed up. A matching certificate is currently published for this product and strength. Open the 10 mg certificate.
A Melanotan II order needs three vials to qualify for free Standard tracked post in Australia, because it is one of the lower-priced products at Australian Research Peptides and two vials fall under the threshold. Adding the consumables a dry vial can't be used without takes a two-vial order most of the way there. Free Express Post has a separate, higher threshold. Both are judged on the subtotal before any discount.
No, Melanotan II is not the same compound as PT-141, which is bremelanotide, a different molecule that differs at one end of the shared ring. PubChem gives PT-141 the formula C50H68N14O10 and Melanotan II C50H69N15O9. Each has its own listing, with its own stock and its own testing. This pair is confused more often than any other in the Australian Research Peptides catalogue, so check which compound a comparison actually names.
Melanotan II works as a lab-made version of alpha-MSH, one of the body's own hormones, binding to melanocortin receptors and switching them on, which is what an agonist does. The Guide to Pharmacology lists it as a full agonist at four human receptor subtypes: MC1, MC3, MC4 and MC5. MC1 is found on melanocytes, the pigment-making cells. MC3 and MC4 are found mostly in brain tissue, which is where the rest of the receptor research sits.
Buying, price and availability
Melanotan II is supplied in Australia by Australian Research Peptides (ARP), and its batches are HPLC-tested by an independent laboratory commissioned by the manufacturer. Australian Research Peptides lists this vial alongside PT-141 under Melanocortin Agonists and doesn't carry Melanotan I. As an Australian business, it posts within Australia rather than across a border, and accepts PayID or direct bank transfer.
Melanotan II costs A$79.99 for the 10 mg vial (out of stock) at Australian Research Peptides, which sells it to laboratories and researchers in one size, so there are no strengths or per-milligram rates to compare. It holds the HPLC Verified grade, and its lab certificate is published on the certificates page. Posting restarts when Melanotan II is back in stock.
You can get Melanotan II online from Australian Research Peptides, an Australian seller that posts within the country and sends nothing overseas. Payment is by PayID or bank transfer, so wallets, instalment plans and crypto aren't accepted. A new order gets its own payment reference and bank details by email, and the vials stay reserved until the payment is matched. Orders aren't taken by phone.
No, you can't buy Melanotan II at Chemist Warehouse or any other Australian pharmacy, but it is available from Australian Research Peptides. It isn't a registered medicine in Australia and no approved formulation exists, so there is nothing a pharmacist could lawfully supply. Australian Research Peptides supplies it strictly as a research compound, sealed in a glass vial for laboratory use.
Identity, names and exact format
A Melanotan II vial holds freeze-dried peptide powder and nothing else, with no diluent, solvent or preservative added and nothing pre-mixed. The quantity is recorded against the vial in the Australian Research Peptides catalogue. The glass vial is tamper-evident, so a broken seal is visible before you open it. Any diluent is chosen by the laboratory and isn't part of the vial.
Melanotan II has seven amino acids, making it a cyclic heptapeptide, built from the 4-to-10 section of alpha-MSH, a natural hormone thirteen amino acids long. A lactam bridge links the aspartic acid to the lysine and closes the chain into a ring. That bridge is the design change that sets Melanotan II apart from the straight-chain Melanotan I.
Melanotan II is commonly shortened to MT2, which is also the stock code Australian Research Peptides uses for it on this listing. PubChem lists the free base under CAS 121062-08-6 and includes Melanotan II acetate among its other names. Melanotan I, also called afamelanotide, is a separate compound, not another name for Melanotan II.
Melanotan II is supplied by Australian Research Peptides as a single 10 mg vial of freeze-dried powder (stock code 73731), not as a nasal spray. It isn't a solution or a pre-mixed device of any kind, so it has to be reconstituted before laboratory work begins. Nasal products sold elsewhere carry the same peptide in a different form, and nothing in this listing supplies one. The figure on the label is the dry weight sealed inside the vial.
MT2 is the short name for Melanotan II, and both names refer to the same compound and the same listing at Australian Research Peptides. People also type melano tan 2 as two words, melanotan2 as one, or mt 2 peptide. These are just search habits, not different products, and searching plain melanotan leads here too, because Australian Research Peptides doesn't carry Melanotan I.
Handling, storage and measurements
Yes, it is normal for a Melanotan II vial to look nearly empty, because ten milligrams of dry ring-shaped peptide looks like almost nothing once freeze-drying has removed the water. Many vials show only a whitish ring around the base or a scattering of fine particles. With this compound, colour matters more than volume: good dry material is white to off-white, so a browned or yellowed deposit is the real warning sign.
Melanotan II should be stored dark, dry and below -15 °C, colder if possible, because it contains tryptophan, the amino acid most prone to oxidising. That temperature is Bachem's guidance for dried peptides. Before opening, let the vial come back to room temperature in a desiccator, a sealed box that keeps the air dry, or the powder will pull in moisture. Reseal it tightly. Solutions should be split into small single-use portions (aliquots) and kept frozen.
Melanotan II does degrade over time, but sealed powder kept cold and dry is in its stable state, while after reconstitution it must be refrigerated and has a much shorter life. Signs that a mixed vial should not be used are cloudiness, particles, or powder that won't fully dissolve. A change of colour in the dry cake is also a reason to stop.
To reconstitute Melanotan II, let the sealed vial reach room temperature, aim the diluent at the side of the glass rather than the powder, and roll the vial gently between your fingers until the liquid clears. Don't shake it. This ring-shaped peptide dissolves without much coaxing, and Bachem suggests a water-bath sonicator for any particles that hold out. Then split it into portions and freeze.
Reconstituted Melanotan II keeps for eight to twelve weeks in the fridge at 2–8 °C, though how quickly it breaks down in a chilled vial has never been published. Melanotan II closes its ring with an amide, and losing that amide produces the free acid listed separately as PT-141, so its chemical fate in water is known, just not the speed.
With Melanotan II, haze that clears quickly after mixing and haze that lasts mean opposite things, so wait a few minutes before judging the vial. Air mixed in while the powder dissolves clears within minutes, and a vial used straight from the cold also takes a little longer to clear. Cloudiness that stays after the vial has warmed and rested, or solid on the bottom that won't dissolve, means the peptide hasn't dissolved properly or has clumped (aggregated). Discolouration of the dry powder is just as important a warning.
Melanotan II ships as a dry cake and must be dissolved before it is pipetted, usually in a water-based (aqueous) diluent. Diluent simply means the liquid a powder is dissolved in, nothing more technical than that. The laboratory supplies it, because nothing liquid is packed in the box with the vial.
No, a Melanotan II vial isn't ready to pipette as supplied, because it arrives sealed with dry powder inside and must be dissolved in a diluent before any volume can be measured from it. The vial holds only the peptide, and the laboratory chooses its own diluent and measuring equipment.
Testing and batch documents
Melanotan II 10 mg from Australian Research Peptides is 99.877% pure by HPLC, the figure on its published certificate of analysis, dated 19 June 2026. That report is by Janoshik, an independent laboratory commissioned by the manufacturer rather than by Australian Research Peptides, and the figure applies to the batch it tested. The full certificate is in the COA library.
Ordering, payment and Australian delivery
To pay for Melanotan II, choose a payment method at checkout, and the stock is then held for two business days while your payment clears, with reminder emails sent along the way. If payment hasn't arrived by the deadline, the reservation lapses and the vials go back into general stock. This isn't a penalty; the stock is simply released for someone else.
Melanotan II usually arrives within 2–5 business days by standard tracked post in Australia, or in as few as 1–2 by Express Post, depending on the destination state. Those times are for capital cities. Regional or remote addresses usually take longer, for example a WA mining town compared with Perth, or far north Queensland compared with Brisbane, and that difference comes from the carrier, not from Australian Research Peptides.
Access and regulatory questions
Melanotan II is not approved by the TGA and is not a registered medicine in Australia, and the TGA has issued public warnings about products containing it. Australian Research Peptides supplies it as a laboratory research chemical, not for use in people or animals. Any obligations that come with holding it are yours to check, not the supplier's to resolve.
Melanotan II is not registered with the Therapeutic Goods Administration (TGA) in Australia, which makes it an unapproved good rather than a medicine that can be prescribed. The TGA has publicly warned consumers against unapproved products containing melanotan. Australian Research Peptides sells Melanotan II strictly as a lab reagent for glassware and cultured cells, not as a therapeutic good, and gives no advice on use to anyone for any purpose.
Yes, Melanotan II is banned in sport all year round, because no government health authority anywhere has licensed it, placing it under S0, the catch-all category for substances the list doesn't name individually. The intended purpose makes no difference, because the anti-doping rule looks only at what a sample contains. Sport Integrity Australia handles questions from Australian athletes.
Melanotan II ordered from an overseas seller can be detained on arrival, because unapproved goods are exactly what border screening targets, and once a package is held there is rarely any recourse against a foreign seller. Ordering from Australian Research Peptides avoids that completely, because it sends orders within Australia and never presents a parcel for customs clearance. Australian Border Force publishes what it detains and under whose authority.
