Advancing Research Integrity in Canada's Peptide Supply Chain
Performance Peptides Canada is a domestic supplier of laboratory-grade research peptides, established to solve a problem that had become endemic in the Canadian life sciences sector, the systematic failure of international supply chains to deliver compounds that actually meet the purity specifications on the label.
The peptide research supply market in Canada has long been dominated by international vendors shipping from overseas facilities. For Canadian researchers, this created a recurring set of compounding problems: extended customs delays at CBSA inspection points, non-climate-controlled storage during those holds, inconsistent purity documentation, and no meaningful recourse when compounds arrived degraded or mislabeled. The research suffered. The data suffered. And the cost, in both dollars and time, was absorbed entirely by the researcher.
Performance Peptides Canada was built as the domestic alternative. Every compound in our catalog ships from within Canada, is tested to a minimum of 99% purity by third-party HPLC and Mass Spectrometry analysis, and arrives with a batch-specific Certificate of Analysis that can be verified independently.

Our Scientific Standard: Purity Verified by HPLC and MS Analysis
Purity claims in the peptide research market are common. Verified purity is not.
The distinction matters because synthesis quality varies significantly between production lots; a COA from a previous batch tells you nothing about the vial in your hand. At Performance Peptides Canada, every batch undergoes independent third-party analytical testing before it enters our inventory. There are no exceptions.
Our testing protocol covers three non-negotiable checkpoints:
- Identity Verification: Mass Spectrometry confirms the molecular weight and amino acid sequence of every compound matches its theoretical specification within a tolerance of +/- 1 Dalton
- Purity Assessment: HPLC chromatographic analysis confirms a minimum of 99% purity, with the primary peak assessed for both height and symmetry. Broad or shouldered peaks indicate synthesis by-products regardless of the percentage figure
- Contaminant Screening: Every batch is screened for residual TFA (Trifluoroacetic acid) levels and residual solvents, both of which can alter the pH of a research environment and introduce experimental variables that are difficult to trace back to source
Batch-specific Certificates of Analysis are available directly on each product page. We publish them because we believe researchers should be able to verify the data independently, not because we are required to.

COA Type | Batch-Specific, Third-Party | Generic or In-House |
Fulfillment | 100% Domestic Canada | International, High Customs Risk |
Cold-Chain | Maintained Throughout | High Risk of Failure in Transit |
Why Domestic Fulfillment Is a Data Integrity Issue
The decision to source peptides domestically is not merely a logistical preference; it is a research integrity decision.
Lyophilized peptides are stable compounds under the right conditions. The problem is that international shipping exposes them to conditions that are anything but right. CBSA secondary inspection holds of 10 to 21 days are common for synthetic reagents entering Canada in 2026. During those holds, packages sit in non-climate-controlled warehouses at temperatures that vary dramatically depending on the season and the facility. For thermally sensitive sequences like Tesamorelin or TB-500, 48 hours at ambient temperature begins the process of peptide aggregation. Fourteen days can render a compound functionally useless for high-precision assays, while it still looks identical to a fresh batch on visual inspection.
Every order placed with Performance Peptides Canada ships from within Canadian borders. There is no customs exposure, no secondary inspection risk, and no cold-chain gap between our facility and your laboratory.
Our Commitment to Research Compliance
All compounds offered by Performance Peptides Canada are intended strictly for in-vitro laboratory research use only, in accordance with Health Canada guidelines for synthetic research reagents. These products are not intended for human consumption, veterinary use, or diagnostic purposes.
We take our responsibility to the Canadian research community seriously. That means supplying compounds that meet the analytical standards the research demands and being transparent about the testing that confirms it.

What does 99% HPLC Purity actually mean for a peptide?
HPLC purity refers to the percentage of the target peptide sequence relative to all other peptide impurities detected in the sample. A 99% purity rating means 99% of the peptidic content is the correct sequence. It is important to understand that net peptide content, which accounts for residual water and counter-ions such as acetate or TFA salts, is typically 70% to 85% of the total powder weight even in a 99% pure sample. This distinction matters for accurate molar calculations in the lab.
Why is a batch-specific COA more important than a generic one?
A batch-specific COA provides verifiable proof that the exact vial you received has been independently tested for both identity and purity. Synthesis quality varies between production lots. A generic COA referencing a different batch provides no meaningful assurance about the compound in your hand. At Performance Peptides Canada, every COA is linked to a specific lot number and generated from third-party analytical data.
What is the correct way to store lyophilized peptides?
For long-term stability, lyophilized peptides should be stored at -20°C or colder in a dry, dark environment. Always allow the vial to equilibrate to room temperature before opening, particularly relevant in Canadian winters where indoor humidity fluctuations can cause condensation on a cold vial, accelerating degradation from the moment it is opened.
How long do reconstituted peptides remain stable?
Once reconstituted in a sterile diluent such as Bacteriostatic Water, peptides should be stored at 2°C to 8°C and used within 14 to 30 days, depending on the specific sequence. Avoid repeated freeze-thaw cycles, each cycle introduces mechanical stress on the peptide chains and reduces the effective biological activity of the solution over time.
