Research results are only as reliable as the materials behind them. With so many online peptide suppliers, quality varies widely, and a polished website says little about what is in the vial. This checklist gives researchers a structured way to compare suppliers before ordering.
- Prefer suppliers that publish batch-specific, third-party test reports.
- Traceability matters: the batch on the vial should match the report.
- Clear shipping, storage and returns information is a sign of a serious operation.
- Be wary of unusual claims, missing contact details and prices far below the market.
The 10-point checklist
- Batch-specific COAs. Reports should be tied to the batch you receive. See how to read a COA.
- Independent testing. Third-party labs add credibility, especially if the lab can confirm the report.
- Both purity and identity. HPLC and mass spectrometry together.
- Endotoxin data for cell-based work.
- Clear labelling with compound name, amount, batch and storage guidance.
- Honest research-use-only positioning with no health or benefit claims.
- Transparent shipping times, packaging and carriers, ideally within your country. See shipping and returns.
- Real contact details and a support channel that answers.
- Clear policies on returns, damaged shipments and terms.
- Reasonable pricing. Prices far below everyone else can signal under-dosing or poor quality.
Red flags
- Reports without batch numbers, or the same report used for everything.
- Promises about health outcomes or treatment.
- No company name, address or contact route.
- Pressure tactics and countdown timers.
- Payment methods with no explanation. See how our options work in the payment guide.
Buying within Canada
Ordering from a domestic supplier typically means shorter transit, less heat exposure and no customs surprises. Shorter transit also helps stability; see how heat affects peptides. Prices should be shown in Canadian dollars with all costs visible before you pay.

Frequently asked questions
What is the most important thing to check?
That the batch number on your vial matches a complete, verifiable test report that includes a chromatogram and mass spectrum.
Are cheap peptides lower quality?
Not always, but prices far below the market deserve scrutiny. Ask for the test report and compare it with other batches.
Why does research use only matter?
It means the product is intended for laboratory work and not for human or animal use, and the supplier should not make health claims.
Should I test peptides myself?
Independent testing is the strongest verification available. Some researchers send samples to a third-party lab for confirmation.
