Email info@certbiohealth.ca or fill out our contact form with your peptide name/sequence, test requirements, and quantity. We respond within 1 business day with pricing and a test requisition number.
Package your lyophilized peptide in a labelled vial. Include: your requisition number, peptide name, approximate molecular weight, and any supplier COA you want us to verify. Minimum quantities per test type are listed below.
Ship via overnight courier (FedEx, UPS, or Canada Post Xpresspost) to our Toronto laboratory. Include a printed copy of your requisition form inside the package. Samples should be kept cool during transit where possible.
Upon receipt, we log your sample into our Laboratory Information Management System (LIMS) and send you a confirmation email with your sample tracking ID and expected report date.

Yes. We accept international mail-in samples. Please contact us before shipping so we can provide the correct import documentation and ensure no customs delays. Samples from the US can typically be shipped with a commercial invoice stating "analytical testing samples, no commercial value."
Lyophilized peptides are generally stable at room temperature for short transit periods (1–3 days). For sensitive peptides or solutions, we recommend shipping with a cold pack. Please do not ship on dry ice without contacting us first, as this may affect customs clearance and sample receipt procedures.
Contact us before shipping if your available quantity is below the minimum listed above. In some cases, we can adjust the protocol or prioritize tests to work with limited material. We will never use more sample than required.
Your COA is delivered as a signed, watermarked PDF to the email address provided in your requisition form. A copy is also stored in our LIMS accessible to you upon request. We do not share results with any third party without your explicit written consent.
