CoreMass Laboratories
Canadian lab with fixed CAD pricing, net content by calibrated LC-MS and a public report lookup.
An independent third-party analytical testing laboratory in Canada. CoreMass confirms identity by LC-MS, measures chromatographic purity by HPLC-UV and quantifies net peptide content against a calibrated standard curve, so a report says how many milligrams are actually in the vial as well as how pure the material is. Every price is published in Canadian dollars with no quote step, checkout works as a guest, and every certificate carries a report number and QR code that anyone can look up on the laboratory's own site. It states that it does not manufacture, sell or endorse any tested material.
Services and pricing
CA$300 for purity and identity, CA$350 with net content. Fixed prices published up front.
Purity and identity
CA$300Chromatographic purity by HPLC-UV (area percent) and identity by mass on LC-MS. The starting point for every sample.
Net content
+CA$50An add-on to purity and identity: the measured amount of the target compound in the sample, quantified against a calibrated standard curve.
Endotoxins
CA$275Requires its own sealed vial, separate from the vial used for other tests.
Sterility (PCR)
CA$250Sterility by PCR. Requires its own sealed vial, separate from the vial used for other tests.
Heavy metals
CA$150Heavy-metal screening, added to any sample at submission.
Conformity
CA$75 per vialExtra vials from one lot, checked against the first.
Fentanyl screen
CA$60A safety screen that can be added to any sample.
pH analysis
CA$95Vial photo
Included with every sampleA photograph of the vial as received.
Methods
- HPLC-UV for chromatographic purity, reported as area percent
- LC-MS for identity by mass
- Quantitation against a calibrated standard curve for net content, with reference-standard calibration on every run
- PCR for sterility
What the certificate carries
- Report number, purity, identity, net content, method, status and received date
- Chromatogram at 220 nm, retention time and calibration R²
- A SHA-256 report hash, and a QR code linking to the laboratory's verification record
- Delivered electronically, never by mail
- Report numbers are four letters and seven digits, printed at the top right of every certificate, and can be looked up on the laboratory's site with no account
What to send
- Label the vial or container with the Order ID issued at checkout
- Endotoxin and sterility each need their own sealed vial, separate from the vial used for other tests
How submission works
- 1Order onlineChoose the tests and check out. No account is needed; checkout works as a guest.
- 2Receive an Order IDThe Order ID and submission instructions, including the receiving address, arrive by email straight after payment.

- 4Get the certificateAn email arrives when the report is issued. Most analyses complete within 5 to 7 business days of the sample arriving.
Best for
A Canadian sample where you want a fixed price in your own currency before you ship, a measured milligram figure rather than purity alone, and a certificate a third party can look up.
Shipping from Canada: Domestic for a Canadian sample. The receiving address is provided with the order.
CoreMass Laboratories questions
Do I need an account to order?
No. Checkout works as a guest. After payment you receive an Order ID and submission instructions by email, and that Order ID is used to track your sample and retrieve your report.
What's the difference between purity and content?
Purity is the share of the detected material that is the target compound. Net content is the actual measured amount of that compound in the sample. A sample can be highly pure yet contain less than its labelled amount.
How does report verification work?
Every Certificate of Analysis has a unique report number and QR code. Anyone can enter the number on our verification page to confirm the report is authentic and unchanged.
