Quality & testing
Every batch is tested — and the proof is public
We compete on verifiability. Every batch is third-party tested by Testides and Peptide Test Canada, with a published certificate of analysis, linked from every product page.
Our testing process
Batch intake
Each lot is received with a documented batch ID that is carried through to its certificate of analysis.
Third-party testing
Every lot is tested by independent Canadian analytical labs — Testides and Peptide Test Canada. Testing is independent of production.
HPLC + mass spectrometry
High-performance liquid chromatography measures purity; mass spectrometry confirms identity and molecular weight.
Publish & ship
The certificate is posted to our public lab-results library before the lot ships. Nothing is held “on request.”
Clear sterile glass vials with lyophilized peptide powder.
What a certificate shows
- Purity %
- Measured by HPLC against a ≥ 98–99% minimum specification.
- Content (mg)
- Peptide mass on the certificate versus the stated amount — quantity, not just purity.
- Identity
- Confirmed by mass spectrometry against the expected molecular weight.
- Lot / batch ID
- Identifies the tested batch in our library and on the certificate PDF.
- Test date
- The date the specific lot was analysed.
Test it yourself — on us if we're wrong
If you send any lot for independent third-party analysis and it comes back below the stated purity specification, we refund the order in full and reimburse the documented cost of your test. Every lot is tested before it ships, so we stand behind this.
