About PT-141
Research on PT-141 focuses on the melanocortin receptors, five docking points on cells numbered MC1R to MC5R. PT-141 is an agonist at them, meaning it binds a receptor and switches it on. Published receptor-binding data ranks its potency with MC1R first, then MC4R, MC3R, MC5R and MC2R. Australian Research Peptides reports that published work and nothing beyond it.
PT-141 is bremelanotide. It is a cyclic heptapeptide, which means its seven amino acids form a closed loop rather than a strand with two loose ends. Its molecular formula is C50H68N14O10, and the ring is closed by a lactam bridge, a bond that joins the chain back onto itself.
Australian Research Peptides supplies PT-141 to laboratories and researchers from within Australia and posts it domestically, so no order crosses a border. The vial is sealed, tamper-evident glass, and the powder inside is freeze-dried and almost white. The powder is HPLC-tested, and its certificate is published in the CoA library. It is sold for laboratory work in glassware and cell culture, and Australian Research Peptides reports published research rather than giving its own guidance.
BAC water (bacteriostatic water) is also sold by Australian Research Peptides.

Quick answers
PT-141 is supplied in Australia by Australian Research Peptides, which sells to laboratories and researchers, as one 10 mg vial for A$89.99, in stock and sent from Sydney, tested at 99.953% HPLC purity per its Janoshik certificate (June 2026). The freeze-dried vial sits in the Melanocortin Agonists range. Orders completed before 12pm Sydney time on a business day are dispatched the same day by Express Post or standard tracked post, reaching every state and territory without crossing a border.
PT-141 is a synthetic cyclic analogue of alpha-melanocyte-stimulating hormone (α-MSH), and it is studied as an agonist at the five melanocortin receptors, MC1R to MC5R. An agonist of this kind switches a receptor on rather than blocking it. Australian Research Peptides supplies PT-141 as freeze-dried research material to laboratories and researchers, for in vitro research only.
Yes, PT-141 10 mg was analysed on 19 June 2026 by Janoshik, an independent laboratory commissioned by the manufacturer, which recorded 99.953% purity by HPLC. That figure describes the batch tested rather than the listing as a whole. A matching certificate is currently published for this product and strength. Open the 10 mg certificate.
A PT-141 order qualifies for free Standard Post in Australia at three vials, or at two vials plus a second compound from the range, because two PT-141 vials on their own fall short. Free Express Post starts at a higher amount. Australian Research Peptides checks this on the value of the goods before any discount code is taken off.
PT-141 is described as working by activating the melanocortin receptors on the surface of cells, binding all five of them, which is why it is called non-selective. Published binding data ranks its potency with MC1R first, then MC4R, MC3R, MC5R and MC2R. Each of the five is a G-protein-coupled receptor, which passes its signal into the cell through a G protein. Australian Research Peptides reports that receptor pharmacology and nothing beyond it.
Buying, price and availability
Australian Research Peptides Pty Ltd supplies PT-141 to laboratories and researchers across Australia, listing it as PT141 in its Melanocortin Agonists range and posting only within the country. The 10mg freeze-dried vial is packed and lodged the same business day for orders received before 12pm Sydney time, Monday to Friday, then sent by Express Post or standard tracked post to any Australian state or territory. It never crosses a border or waits at customs, and the batch's HPLC certificate is in the CoA library.
PT-141 costs A$89.99 for the 10 mg vial (in stock) at Australian Research Peptides, which lists it in that single size, so there is no second strength to compare. A second vial costs the same as the first, and postage is added according to the service chosen. When paid before 12pm Sydney time on a weekday, an order is dispatched the same day.
You can get PT-141 online from Australian Research Peptides, which supplies it to laboratories and researchers throughout Australia and accepts payment by PayID or bank transfer. Your order is prepared once payment is confirmed, then posted from an Australian address. PT-141 vials come sealed and are for in vitro research purposes only, and the CoA library shows which strengths have a published certificate.
No, PT-141 isn't on the shelf at Chemist Warehouse or any other Australian pharmacy, because it is laboratory research material rather than a pharmacy product. Instead, Australian Research Peptides offers PT-141 online as a single 10 mg vial of laboratory material, sold to laboratories and researchers rather than to consumers.
Identity, names and exact format
A PT-141 vial contains only the PT-141 peptide itself as a freeze-dried solid, with no diluent, no carrier, no preservative and no second peptide. The milligram figure on the listing is the weight of peptide in the vial, under a tamper-evident seal. Anything needed to dissolve it is chosen by the laboratory and isn't included.
PT-141 is made up of seven amino acids, which is why it is called a heptapeptide, and those seven are joined into a ring rather than a strand with two loose ends. Chemical registries write the sequence as Ac-Nle-cyclo(Asp-His-D-Phe-Arg-Trp-Lys)-OH. The number seven describes the molecule, not the vial, and the milligrams of powder in the vial is a separate figure entirely.
PT-141's CAS number is 189691-06-3, the registry number PubChem lists for PT-141 as the free base, meaning the peptide on its own without a salt attached. A salt form such as an acetate has its own registry number, and Australian Research Peptides hasn't confirmed which form its PT-141 vial holds. So this number identifies the compound, not the exact form sealed in the vial.
Peptide 141 is how people write PT-141 when the letters and number get separated, and it means exactly the same compound as the 10 mg research vial listed here. PT141 without a hyphen, pt 141 with a space, and the shortened search pt 141 peptid all lead to the same product. The hyphen makes no difference, and no spelling points to a different compound.
Research context and evidence
Australian Research Peptides publishes what a PT-141 vial contains, the batch certificate with its measured purity, and how to make a solution from the powder. It publishes no usage guidance of any kind, because PT-141 is supplied only as a bench reagent for in vitro laboratory research, not for use in people.
Handling, storage and measurements
Yes, it is normal for a PT-141 vial to look empty, because ten milligrams of this ring-shaped peptide dries into a small, compact pale wafer that blends into clear glass. Light from overhead hides it completely, but light from the side makes it visible again. The amount is measured by weight when the vial is filled, not by how full the vial looks.
PT-141 should be stored in its sealed, tamper-evident vial, kept cold, dark and dry, and below -15 °C for long-term storage, following Bachem's handling guidance for freeze-dried peptides. Colder still is better. Let the vial reach room temperature before opening it, so moisture doesn't settle on the powder. Once made, a PT-141 solution doesn't last long, as peptide solutions aren't meant for long-term keeping.
To reconstitute PT-141, add a suitable diluent to the vial slowly, letting it run down the inside of the glass rather than aiming it straight at the powder. Swirl gently and let the powder dissolve on its own, because shaking only whips air into it. Wait until the liquid is clear before doing anything else. The volume you add sets the concentration of the PT-141 solution.
Reconstituted PT-141 keeps for up to twelve weeks at 2–8 °C under Australian Research Peptides' published storage condition, and anything kept longer should be frozen in portions. PT-141 is a ring closed by a lactam bridge, a bond that joins the molecule back onto itself, and it ends in a free acid. The tryptophan inside that ring is sensitive to light, so keep the solution in the dark.
There is no set volume of diluent for a PT-141 vial, because the vial always contains 10 milligrams of dry peptide, whatever amount of liquid is added to it. Australian Research Peptides publishes no fill volume, so how much diluent to add is decided by the work being done, not by the listing. More liquid gives a weaker solution and less gives a stronger one.
Freshly reconstituted PT-141 often looks hazy for a minute or two while air bubbles from mixing rise out, and this clears up on its own. Cold liquid dissolves the powder more slowly and can look the same. What matters is how it looks after about ten minutes at room temperature: a good PT-141 solution is clear, with nothing floating in it. If it stays cloudy, don't go any further.
PT-141 is normally dissolved in an aqueous (water-based) diluent for laboratory work, because it ships as a dry cake of cyclic peptide sealed in glass and needs a liquid before any work can begin. A diluent is any liquid used to dissolve a dried compound. No liquid is packed in the vial, so the laboratory supplies its own.
Yes, a 10 mg PT-141 vial is normally dissolved all at once, in one step, and the volume of liquid added sets the concentration of the solution. Splitting that solution into labelled portions for the freezer stops the whole batch being thawed and refrozen again and again, and writing the concentration on each label keeps the lab records straight.
Testing and batch documents
PT-141 10 mg from Australian Research Peptides is 99.953% 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
PT-141 usually takes 2–5 business days to arrive by standard tracked post, while Express Post cuts that to 1–2 business days for most of Australia, or 2–4 for Western Australia, Tasmania and the Northern Territory. Every PT-141 parcel is sent from an Australian address and stays in the domestic post the whole way.
You can pay for a PT-141 order online by PayID or bank transfer, the two methods Australian Research Peptides accepts. Both are sent from your own bank, so you never type a bank login or password into this site, and each is paid using the order confirmation, which shows the reference to include.
Access and regulatory questions
Australian Research Peptides sells PT-141 to laboratories and researchers in Australia for in vitro laboratory research only, and does not supply it as a medicine or a therapeutic good. The TGA regulates therapeutic goods under the Therapeutic Goods Act 1989. PT-141 from Australian Research Peptides is laboratory material, not for human or animal use.
PT-141 is used in melanocortin receptor pharmacology, the lab study of how molecules bind to and switch on the five melanocortin receptors, MC1R to MC5R. Published binding studies describe it as a non-selective agonist across that whole family. Australian Research Peptides supplies PT-141 for in vitro work of this kind, in glassware and cell culture, and adds no claims of its own to the published research.
Australian Research Peptides can't clear PT-141 for sport, because anti-doping status comes from the World Anti-Doping Agency's Prohibited List, which Sport Integrity Australia applies in Australia. Australian Research Peptides gives no ruling on any compound, in or out of competition. PT-141 is sold only to laboratories and researchers for in vitro work.
Ordering PT-141 from Australian Research Peptides involves no importing, because it is held and posted within Australia, so no parcel goes through Border Force or waits on customs clearance. That is also why local supply is quicker than an overseas order. Anyone importing PT-141 themselves is subject to the TGA's own import conditions. This answers a delivery question, not a regulatory one, and it doesn't change what the material is or the holder's own obligations.
PT-141 is for laboratories, universities and independent researchers working on melanocortin receptors, and Australian Research Peptides supplies it for in vitro research in glassware and cell culture. It is a research compound, not a medicine or a supplement, and it is not sold to members of the public for their own use. Australian Research Peptides gives no guidance on using it.
