The Receptor Research Standard

Proof Over Promises. Every Single Time.

At Receptor Research, transparency and quality come first. Every batch is supported by independent analytical testing, with Certificates of Analysis (COAs) available for review. We believe research should be backed by verifiable data, clear documentation, and consistent quality standards — so you can review the evidence behind every product.
Batch-Specific COAs

Lab Verified

Verified by independent third-party testing

We don’t grade our own work. Every batch is independently tested, and only batches that meet spec are listed. Each certificate includes the batch number, testing method, laboratory, and date. Match the vial’s batch number with our archive to verify authenticity.

HPLC purity, run per batch — not once per product line

LC-MS confirmation that the molecular mass is what the label says

Endotoxin and sterility screening on all reconstitutable peptide products

A public batch archive — no account, no request form

Quality assurance

How the testing works

Assaying every vial size of every compound would cost more than the compounds do, and a supplier claiming otherwise is either charging for it or not doing it. So here is the actual scope. One sample is drawn from each production batch, at the fill weight most labs order, and sent for independent analysis. The other fill weights in that batch come off the same synthesis run, the same raw material lot and the same QC process, so the result carries across them. The certificate states which sample was drawn, so nobody has to take our word for the scope.

01

Select sample

A vial is pulled from the finished batch, at the fill weight most labs order.

02

Independent analysis

The sample goes to JANOSHIK for HPLC purity and LC-MS mass confirmation.

03

Published result

The certificate is uploaded against the batch number and stays in the public archive.

Purity that’s on the record

Purity figures come from an independent laboratory, per batch, and they get published whether or not they flatter us. The number on the certificate is the number.

FAQ

Common Questions

How is purity verified?

Each batch is sampled and sent to an independent analytical laboratory. Purity is measured by HPLC (high-performance liquid chromatography) and molecular mass is confirmed by LC-MS (liquid chromatography–mass spectrometry). The certificate for each batch is published in the lab results archive.

Because the cost of assaying every fill weight of every compound would land on the invoice. One sample is drawn per production batch, at the most commonly ordered fill weight. The remaining fill weights come from the same synthesis run and the same raw material lot, so the result applies to the batch. The certificate states which sample was tested.

That the material is manufactured and supplied for laboratory research and analytical work, with an independent assay behind it. It is not a pharmaceutical grade, not a therapeutic good, and not approved for use in humans or animals. Research grade describes the intended use and the documentation, not a safety rating.

Qualified researchers and authorised representatives of research organisations. Placing an order confirms the material will be handled by trained personnel in an appropriate laboratory setting.
No. We supply materials and the analytical data behind them. We don’t provide protocols, handling procedures or application guidance, and we don’t answer questions about use through any channel.

Orders are dispatched within 24 hours, Monday to Saturday. Once dispatched, delivery usually takes 2–3 business days. Tracking details are provided when your order is sent.

Please note: Delivery times are estimates and may vary depending on Australia Post and local postal services.

PayID / bank transfer. Prices are in AUD.

Yes. The certificate for the batch received is in the lab results archive, searchable by the batch number printed on the vial, and a direct link is included in the dispatch email.

Email [email protected] with a photo of the vial and the order number. If a vial can’t be matched to a published batch, it gets replaced or refunded.
