FAQ: Peptide Ordering in Canada
What is the purity level of your research peptides?
Every peptide batch undergoes HPLC and Mass Spectrometry (MS) verification to ensure purity exceeding 99%. Certificates of Analysis (COA) are available for all research materials upon request.
Are DurhamPeptides products safe for human consumption?
No. All products offered are strictly for laboratory research and development (R&D) purposes only. They are not intended for human consumption or therapeutic use.
How should research peptides be stored after delivery?
To maintain biological stability, lyophilized peptides should be stored in a cool, dry environment. For long-term viability, we recommend storage at 2°C-8°C in a laboratory setting.
Are third-party lab results provided for?
Yes. Providing transparent technical data is central to our mission. Researchers can request digital access to Certificates of Analysis confirming purity and mass
Can I modify or cancel my order after submission?
Orders can be modified within a 24-hour window before laboratory processing begins. Please contact support immediately if an adjustment is required.
What are your standard shipping times within Canada?
We offer Express shipping as standard, with typical delivery across Canada ranging from 1 to 3 business days. Tracking details are provided instantly upon dispatch.
Is same-day dispatch available?
Orders placed before our laboratory cutoff time (5 PM EST) are typically processed and dispatched on the same business day to expedite your research timelines.
What payment methods do you accept?
We accept Interac e-Transfer, with Autodeposit enabled for instant payment confirmation. Send payment to account@durhamcorp.ca. Due to banking restrictions on the research chemical category, card processing is not available. Full details on our Payment Methods page. No subscriptions, hidden fees, or recurring charges.
How long do peptides last after reconstitution?
Once reconstituted with bacteriostatic water, peptides should generally be used within 30 days when stored at 2–8°C. Unreconstituted lyophilized peptides stored properly at 2–8°C in sealed vials can remain stable for 12–24 months. Avoid repeated freeze-thaw cycles with reconstituted solutions.
Do you ship outside of Canada?
At this time, Durham Peptides ships exclusively within Canada via Canada Post Xpresspost. We do not currently ship internationally. This allows us to guarantee delivery times of 1–3 business days without delays.
Are your peptides tested by a third party?
Yes. Every batch is independently tested by Janoshik Analytical, one of the most respected independent peptide testing laboratories. Each product undergoes HPLC purity analysis and mass spectrometry identity confirmation. Certificates of Analysis are available upon request and can be independently verified directly through Janoshik's verification portal.
