Testides
Testides (also known as testides lab or testides analytics) is a Canadian-based independent analytical laboratory focused exclusively on peptide purity and identity testing for the research community. Unlike European labs that require international shipping and customs exposure, Testides offers domestic Canadian turnaround — samples move within Canada, avoiding cross-border delays, import duties, and the risk of seizure. The lab runs HPLC purity analysis and mass spectrometry identity confirmation, issuing certificates of analysis that are publicly accessible so researchers can independently verify results. Pricing is billed in CAD, eliminating currency conversion overhead for Canadian buyers. For Canadian researchers who regularly test vendor stock — particularly GLP-1 peptides like Semaglutide and Tirzepatide, growth hormone secretagogues, and tissue-repair compounds — Testides is the practical domestic alternative to shipping samples overseas.
Testing Capabilities
Purity Testing
| Test Name | Description | Price Range | Turnaround |
|---|---|---|---|
| HPLC Purity Analysis | Reverse-phase high-performance liquid chromatography (RP-HPLC) separates peptide components by hydrophobicity and quantifies the target peptide as a percentage of total UV-absorbing material. The result is reported as a purity percentage — vendors commonly claim 98%+, and HPLC is the standard method to verify or refute that claim. This is the primary test researchers use to confirm they are not receiving degraded or diluted product. | - | - |
Identity Testing
| Test Name | Description | Price Range | Turnaround |
|---|---|---|---|
| Mass Spectrometry Identity Confirmation | Mass spectrometry determines the molecular weight of the compound in the sample and compares it against the theoretical molecular weight of the target peptide. A matching mass confirms the compound is what the vendor claims it is, guarding against substitution of cheaper or inactive compounds. This test is essential for complex peptides like Semaglutide and Tirzepatide where substitution risk is elevated due to high vendor pricing pressure. Testides reports both observed and expected mass values on the COA. | - | - |

Pros & Cons
Pros
- Domestic Canadian lab: samples ship within Canada, avoiding customs exposure and international delays
- CAD billing removes currency conversion friction for Canadian researchers
- Publicly accessible COAs allow independent result verification without trusting the lab or vendor
- HPLC purity combined with mass spec identity provides both quantitative purity and positive compound identification in one order
- 3-7 business day standard turnaround is competitive for a domestic Canadian operation
- Focused exclusively on peptide testing rather than being a generalist environmental or food lab
Cons
- No rush or expedited service available — not suitable for time-sensitive vendor disputes
- Narrower test menu than Janoshik (no endotoxin, heavy metals, sterility, or residual solvents testing)
- No published ISO 17025 accreditation — results may not be suitable for regulatory submissions
- International researchers would need to ship into Canada, which may negate the domestic turnaround advantage
Frequently Asked Questions
Is Testides a legitimate peptide testing lab?
Yes. Testides is a Canadian analytical laboratory that provides HPLC purity analysis and mass spectrometry identity confirmation for peptide samples. Their certificates of analysis are publicly accessible, meaning any researcher can view results online — a meaningful transparency signal. The lab is not ISO 17025 accredited and is not suitable for regulatory submissions, but for independent third-party verification of research-grade peptides, it operates as a legitimate testing service.
How does Testides compare to Janoshik for Canadian researchers?
The main practical advantage Testides has over Janoshik is geography. Samples ship domestically within Canada, avoiding international postage costs, customs delays, and the risk of package seizure at the border. Janoshik, based in Prague, has a broader test menu (endotoxin, heavy metals, sterility, residual solvents) and a larger community reputation, but Canadian researchers must account for international shipping time and cost. For basic purity and identity testing, Testides is the more convenient domestic option. For a full safety panel, Janoshik remains the benchmark.
What does Testides actually test for?
Testides offers two core tests. HPLC purity analysis quantifies the target peptide as a percentage of total material in the sample — this tells you whether a vendor''s claimed 98%+ purity is accurate or inflated. Mass spectrometry identity confirmation checks the molecular weight of the compound against the expected mass of the target peptide — this tells you whether the compound is actually what the vendor claims it is. Together, these two tests answer the two most important questions about any peptide purchase: is it pure, and is it real?
How do I submit a sample to Testides?
Sample submission instructions and current pricing are available directly on the Testides website at testides.com. Accepted sample types include lyophilized peptide and raw powder. The standard turnaround is 3-7 business days from sample receipt. Rush processing is not currently offered, so plan accordingly if submitting samples tied to time-sensitive decisions.
Are Testides COAs publicly accessible?
Yes. Testides publishes certificates of analysis so that results are independently viewable. Researchers are not required to take the lab''s word for the result. This is an important distinction from simply receiving a PDF COA from a vendor, which can be edited or fabricated. Publicly hosted COAs allow community members to cross-check results and verify authenticity.
Does Testides test GLP-1 peptides like Semaglutide and Tirzepatide?
Yes. Testides performs HPLC purity and mass spectrometry identity testing on complex GLP-1 peptides including Semaglutide and Tirzepatide. This is particularly relevant given the high price point of GLP-1 compounds and the incentive vendors have to dilute or substitute them. Identity confirmation via mass spec is especially valuable for GLP-1 peptides because the molecular weight difference between an authentic compound and a cheaper substitute is detectable analytically.
