The research peptide market has a trust problem.
We started DownUnderPeps because researchers deserve a supply chain they can check for themselves — not another vial with a purity claim and no paperwork behind it.
“Trust us, it's pure.”
- No independent testing
- No batch-level paperwork
- Unclear sourcing
- No cold-chain handling
“Here's the COA. Check it yourself.”
- Independent HPLC + LC-MS testing, every batch
- Public certificate of analysis per vial
- Full batch traceability, start to finish
- Insulated, temperature-controlled dispatch
Built for the bench, not the shelf.

Everything researchers ask before ordering.

Every batch is tested by an independent laboratory using HPLC for purity and LC-MS for identity. The resulting COA is stamped with the batch number and test date, and published to the product page before any vial from that lot ships.
Every vial ships with a tamper-evident seal and a packing slip referencing its batch ID. The matching certificate of analysis — HPLC purity, LC-MS identity, and screening results — is available on the product page and in your account.
Orders placed before 2pm AEST dispatch the same business day. Standard delivery is 2–4 business days across Australia. Free shipping applies on orders over $200.
We stock 34+ research peptides, including melanocortins, GH secretagogues, BPC-157, TB-500, neuropeptides, and metabolic cofactors. The full range is on the catalog page.
