Everything you need to know about ordering research peptides from Peptide Warehouse.
All our products are for research use only — not for human consumption. Before anything leaves our warehouse, every batch is independently tested for purity (99%+), identity, and sterility by a third-party lab. The full results are in our COA Library so you can check them yourself.
Every batch goes to an independent lab — not us — for three tests: purity (we require 99%+ to pass), identity confirmation, and sterility. If a batch fails any one of them, we don't sell it. The results for every batch we've ever stocked are published in our public COA Library.
Yes — every batch has a COA from an independent lab showing the purity result, identity confirmation, and sterility outcome. You can find them in our COA Library any time, no account or purchase required. Just search the batch number that's printed on your vial.
We ship anywhere in Australia via Australia Post with full tracking. Order before 9PM AEST and it goes out the next business day. Standard Post is $9.99 (2–6 business days), Express is $14.99 (1–3 business days), and orders over $199 ship free. Everything arrives in plain, discreet packaging.
Yes — research peptides are legal to buy and possess in Australia for legitimate research purposes. Most of the peptides we stock, including BPC-157, Retatrutide, GHK-Cu, and Melanotan, are not scheduled substances under Australian law when supplied for research use only. You need to be 18+ and confirm research use at checkout. See our Legal page for the full details.
We accept PayID (zero fees), Bank Transfer (zero fees), Credit/Debit Card via Stripe, and PayPal. PayID and Bank Transfer are the lowest-cost options with no processing fees. Card and PayPal payments may carry a small processing surcharge. All available payment methods and any applicable fees are displayed at checkout before you pay.
Keep the vials in the freezer until you need them — they'll stay stable for up to 2 years. Once you mix one with bacteriostatic water (BAC water), move it to the fridge and use within 4 weeks. Keep them away from light and moisture, and avoid repeated freeze-thaw cycles.
We stock BPC-157, Retatrutide, GHK-Cu, Melanotan I and II, Semax, NAD+, TB-500, the BPC-157 + TB-500 Blend, the KLOW blend, and the Retatrutide Research Bundle. We also carry bacteriostatic water and insulin needles. Everything is independently tested before it goes up for sale.
Both are healing-focused peptides but they work differently. BPC-157 is mainly studied for gut repair, tendon recovery, and injury healing. TB-500 is studied more for whole-body tissue repair and cellular recovery. They're often researched together because their effects complement each other — which is why we also stock them as a pre-combined BPC-157 + TB-500 Blend.
