Don’t Trust.Verify Every Batch.
Third-party tested. Results published. Same-day dispatch Mon–Fri.
AusPost Express Australia-wide.
Batch-Level Verification — Not Generic Claims.
Most suppliers test a single lot and re-use that COA across every shipment that follows. Every batch PeptideX receives is independently HPLC-tested by an independent third-party laboratory, assigned a unique batch identifier, and published with its own Certificate of Analysis on a public archive. If we shipped it, you can audit it.
A Transparent Research-First Approach.
PeptideX exists to support laboratories and institutions with documentation, traceability, and unmodified test results — not marketing claims.
Third-party batch testing
Every lot ships with its own COA from an independent third-party laboratory — never a generic per-compound certificate.
Batch ID & traceability
Each batch gets a unique identifier from intake to dispatch. Your order links to one specific lot.
Research handling & storage
Lyophilised peptides held in controlled storage until dispatched. Tamper-evident packaging on every parcel.
Verified research materials
Only batches with a clean published COA enter inventory. Anything below threshold is rejected at intake.
Our focus is process, quality, and clarity — not marketing claims.
How We Verify Every Batch.
A four-stage protocol. No batch reaches the catalogue until every stage is documented.
Intake & Quarantine
Every incoming batch is quarantined, barcoded, and logged with supplier-of-record and receipt date. No lot enters inventory until it has passed §02.
Independent HPLC
Samples sent to an independent third-party laboratory for HPLC purity analysis. The result they issue is the result we publish — unmodified, with the lab’s own signature.
COA Published
Each Certificate of Analysis is uploaded to the public lab-results page promptly after receipt, linked to its batch identifier and permanently archived.
Dispatch from Australia
Only batches with a published, in-spec COA enter dispatch. Same-day dispatch Mon–Fri via AusPost Express, tamper-evident packaging, store credit on lost or damaged parcels.
PeptideX vs Typical Suppliers.
What to look for when evaluating a research-grade supplier — and where most fall short.
Research Questions, Answered.
Clear answers on testing, sourcing, and traceability.
Every batch we receive is sampled and sent to an independent third-party laboratory. They perform HPLC purity analysis and issue a Certificate of Analysis directly. We publish the COA on our lab-results page against the batch identifier assigned to that lot. The specific lab that tested each batch is named on its individual lab-results card.
Your order confirmation email and account portal list the unique batch number allocated to your order at dispatch. Enter that batch number on our public Lab Results page to open the exact COA — purity percentage, testing method, test date, all tied to your specific lot.
We target ≥99% HPLC purity for research peptides, and every published COA shows the actual measured purity for that batch — never a blanket figure. Some material classes carry a different documented specification (for example, cosmetic-grade peptides such as SNAP-8 are supplied to a ≥90% industry standard). Batches that fall below the documented specification for their class are rejected at intake.
These compounds are supplied strictly for in-vitro laboratory research and analytical reference use. We make no medical, therapeutic, or performance claims. Our documentation and handling guidelines reflect laboratory-use expectations.
At present, PeptideX dispatches exclusively within Australia. Domestic-only shipping lets us maintain Mon–Fri same-day dispatch via AusPost Express and consistent customer-care turnaround.
If your parcel is verified lost in transit by AusPost or arrives damaged, we issue store credit to your account once the carrier investigation completes. Open a support ticket through your account portal with the order number — we cross-reference AusPost tracking and apply the credit per our shipping policy.
