PT-141, formally bremelanotide and also written PT141 or PT 141, is a melanocortin-receptor agonist studied for centrally mediated signalling and libido-pathway research. Structurally it is a variant related to the melanocortin family, and it is the best-known compound in the libido research corner of the catalogue, studied for how it engages central melanocortin pathways rather than the vascular pathways older approaches targeted. The 10mg vial is the standard reference format.In preclinical models, bremelanotide is investigated for its activity at melanocortin receptors and the central signalling associated with them. It sits in a specialist niche of the range: the research interest is in precise receptor engagement rather than broad systemic pathways, which is why it is studied as a focused reference compound rather than a general-purpose one.PT-141 shares the melanocortin lineage with Melanotan 2, and researchers comparing melanocortin-pathway compounds often study the two side by side, they engage overlapping receptors but are investigated for different pathway emphases. The single-compound 10mg vial here is the standard reference format for bremelanotide on its own.Every 10mg vial ships lyophilised with an independently verified batch certificate at a guaranteed floor of ≥98% purity, verifiable on the batch verification page using the batch number on the label. Reconstitute with bacteriostatic water: add it slowly down the inside wall of the vial, swirl gently, and never shake. Store the unopened vial at 2 to 8°C; refrigerate the reconstituted solution and avoid repeated freeze-thaw cycles. CAS reference 189691-06-3.Buying PT-141 (bremelanotide) in Australia is domestic and direct: free Australia Post Express shipping Australia-wide with no minimum spend, dispatch from within Australia, and tracking on every parcel. Pay by card, PayPal, or PayID; each vial is sealed under argon with a 24-hour payment reservation on your stock. Supplied strictly as a research material for lawful laboratory and in-vitro use, not for human or veterinary consumption.

- What is PT-141?
- PT-141 (bremelanotide) is a melanocortin receptor agonist studied for centrally mediated signalling and libido-pathway research. It is studied for how it speaks to the central pathways that govern desire, rather than the vascular pathways targeted by older approaches. It is supplied as a lyophilised powder for in-vitro laboratory research purposes only.
- Can I buy PT-141 at Chemist Warehouse in Australia?
- No. PT-141 is not available at retail pharmacies like Chemist Warehouse or Priceline. While bremelanotide (the same molecule) is approved as a prescription medicine for specific indications in some markets, Polaris Research supplies PT-141 exclusively as a research-grade lyophilised powder for in-vitro laboratory research, not as a pharmacy product.
- Where to buy PT-141 in Australia?
- PT-141 10mg is available through Polaris Research with fast domestic Express Delivery to all Australian states and territories. Every vial is dispatched from within Australia with tracking, and each batch is independently third-party tested to ≥98% purity.
- What is the cost of PT-141 in Australia?
- PT-141 10mg is available from Polaris Research with Free Express Delivery Australia-wide and independently verified batch documentation. See the product page for current pricing.
- How to get PT-141 online in Australia?
- Add PT-141 to your cart on the Polaris Research website and complete checkout. All orders are fulfilled domestically and shipped with Australia Post Express tracking to any address across Australia.
- How do I reconstitute the vial?
- Reconstitute by adding Bacteriostatic Water slowly down the inside wall of the vial, never directly onto the powder. Swirl gently to dissolve; do not shake. Once reconstituted, keep the solution refrigerated and avoid repeated freeze-thaw cycles. For a step-by-step walkthrough, see our Peptide Reconstitution Guide.
- How should I store it?
- Store the unopened lyophilised vial refrigerated at 2–8°C, kept dark and upright. Once reconstituted, keep the solution refrigerated and use it within a few weeks. Never re-freeze a reconstituted solution, ice crystals damage the compound. A clear, particle-free liquid is the sign of a clean reconstitution.
- How is PT-141 10mg verified?
- Every batch of PT-141 10mg is independently third-party tested to 99.4% purity by HPLC and mass spectrometry at an accredited laboratory. The batch certificate ships with your order and can be verified on our batch verification page using the batch number on the vial label. We never ship a vial without a matching certificate.
- Is PT-141 10mg shipped Australia-wide?
- Yes, shipping is always free: every order includes free Australia Post Express Delivery, Australia-wide, with tracking. Orders dispatch within 2 business days of confirmed payment, with most dispatched within 24 hours (weekends excluded). A 24-hour payment reservation holds your stock from the moment you order.
- Can I pay with Afterpay or another buy now pay later plan?
- Yes. Afterpay, Zip and Klarna are all offered on Stripe's secure payment page at checkout, alongside card, Apple Pay and Google Pay. Choose the Afterpay, Card & Apple Pay option, then pick your provider on the payment page, where the plan is shown and approved before your order is confirmed. We add no surcharge for paying in instalments, and the price is the same as paying in full. Your order then ships on the normal schedule, most within 24 hours of confirmed payment, so there is no wait for the instalments to finish. Approval and the amount available to you are the provider's decision, not ours. If you would rather pay in full, PayID / Osko bank transfer and PayPal are both offered at checkout.
