Semax, also written as Semax acetate, is a synthetic peptide derived from a fragment of ACTH (adrenocorticotropic hormone), studied for focus, cognitive-performance, neurotrophic-signalling, and attention-pathway research. It is one of the best-known compounds in the brain-function research family and is studied for how it engages neurotrophic pathways, including its relationship with brain-derived neurotrophic factor (BDNF) in preclinical models. The 10mg vial is the standard reference format.In animal and in-vitro research, Semax is investigated for neurotrophic and neuroprotective signalling and for attention- and cognition-pathway models. Its origin as an ACTH-fragment analogue, without the hormonal activity of the parent sequence, is the defining research characteristic and the reason it is studied as a focused neuropeptide reference.Researchers studying nootropic and neuropeptide pathways often look at Semax alongside Selank, its frequent companion in the brain-function family, the two are studied for complementary sides of cognition and calm. Our how-to-choose-a-peptide library guide helps place compounds like these within a wider research plan. The 10mg vial here is the clean single-compound reference for Semax.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 once reconstituted and do not refreeze. CAS reference 80841-56-7.Buying Semax in Australia is domestic: free Australia Post Express shipping to every state and territory, no minimum spend, dispatch from within Australia, and tracking on every parcel. Checkout accepts card, PayPal, or PayID, each vial is sealed under argon, and a 24-hour reservation holds your stock from order. Supplied strictly as a research material for lawful laboratory and in-vitro use, not for human or veterinary consumption.

- What is Semax?
- Semax is a synthetic ACTH(4-10) analogue with Pro-Gly-Pro stabilisation, studied for neurotropic and cognitive-signalling pathways. It belongs to the nervous-system family and is one of the most discussed nootropic peptides in research circles. It is supplied as a lyophilised powder for in-vitro laboratory research purposes only.
- Can I buy Semax at Chemist Warehouse in Australia?
- No. Semax is not available at retail pharmacies like Chemist Warehouse or Priceline. It is a research compound not approved for human use by the TGA. Polaris Research supplies Semax exclusively as a lyophilised powder for in-vitro laboratory research.
- Where to buy Semax in Australia?
- Semax 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 Semax in Australia?
- Semax 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 Semax online in Australia?
- Add Semax 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.
- What does the research show about Semax?
- Semax is studied for its selectivity, a well-matched compound tends to act where its receptors are and stays quiet elsewhere. It is researched for focus, clarity, and cognitive-signalling pathways. As with every neurotropic peptide, the foundations (sleep first, always) are what give it something to amplify.
- 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 Semax 10mg verified?
- Every batch of Semax 10mg is independently third-party tested to 99% 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 Semax 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.
