DSIP, short for Delta Sleep-Inducing Peptide, is a naturally occurring nonapeptide (nine amino acids) studied for sleep-architecture, slow-wave sleep, stress-response, and neuroendocrine research. It was first identified for its association with delta-wave sleep signalling, and it is studied for how it engages the neuroendocrine pathways linked to sleep regulation in preclinical models. The 5mg vial is the standard reference format.In animal and in-vitro research, DSIP is investigated for slow-wave sleep-architecture models and for its relationship with the stress-response and neuroendocrine systems. Its naturally occurring origin and small nonapeptide structure are the defining research characteristics and the reason it is studied as a reference sleep-signalling peptide.DSIP sits in the growth-and-sleep corner of the range alongside the recovery-and-sleep compounds; researchers building a sleep-and-recovery research plan sometimes study it next to the GH-axis peptides. Our how-to-choose-a-peptide library guide helps place it in context. The 5mg vial here is the clean single-compound reference for DSIP.Every 5mg 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 69362-82-5.Buying DSIP 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 DSIP?
- DSIP is a nonapeptide (delta sleep-inducing peptide) studied historically for sleep-architecture and circadian-signalling research. It belongs to the Growth & Sleep family and is studied for its signalling activity in sleep-architecture research. It is supplied as a lyophilised powder for in-vitro laboratory research purposes only, not for human use.
- Can I buy DSIP at Chemist Warehouse in Australia?
- No. DSIP is not available at retail pharmacies like Chemist Warehouse, Priceline, or any Australian pharmacy. It is a research compound not approved for human use by the TGA. Polaris Research supplies DSIP exclusively as a lyophilised powder for in-vitro laboratory research.
- Can Australian compounding pharmacies supply DSIP?
- DSIP is not an approved commercial medicine and is not available as a compounded prescription product through Australian pharmacies. Polaris Research supplies research-grade DSIP for lawful in-vitro laboratory research only, with independently verified batch certificates on every order.
- Where to buy DSIP in Australia?
- DSIP is available through Polaris Research with fast domestic Express Delivery to all Australian states and territories. Every vial is dispatched from within Australia, no customs delays, no international freight uncertainty. Each batch is independently third-party tested to ≥98% purity, with the Certificate of Analysis verifiable on our batch verification page.
- What is the cost of DSIP in Australia?
- DSIP 5mg is available from Polaris Research at $89 per vial with Free Express Delivery Australia-wide and independently verified batch documentation. See the product page for current pricing and any available larger formats.
- How to get DSIP online in Australia?
- Add DSIP 5mg 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. A 24-hour payment reservation holds your stock from the moment you order.
- 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 DSIP 5mg verified?
- Every batch of DSIP 5mg 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 DSIP 5mg 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.
