Testing lab
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.

What it tests
- 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.
- 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.

Prices change; this is what we observed on the date shown, not a quote. The lab's own price list is authoritative.
Accreditation
No accreditation on file. That is a finding, not a blank — an unaccredited lab's numbers rest on its own say-so, which is exactly the situation third-party testing exists to avoid.
Strengths and weaknesses
Where it does well
- 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
