Verification & Quality Documentation
Verify Northbridge
Everything a reviewer, distributor, or researcher needs to evaluate us — our testing methodology, quality commitments, documentation, and company details, in one place.
How we verify quality
Independent third-party lab
Testing is performed by an outside laboratory — not in-house and self-reported.
HPLC purity analysis
High-Performance Liquid Chromatography confirms purity against the stated specification.
Mass spectrometry identity
Mass spectrometry confirms compound identity and molecular weight.
Tested per batch
Analysis is run per batch, with lot traceability tying each COA to a specific production run.
Our quality commitments
- Independent third-party purity testing (HPLC + MS)
- A public, downloadable COA on every product page
- 99%+ purity — verified against specification
- American-made and shipped from the United States
- Same-day shipping on orders placed before 2 PM EST — tracked and discreet
- Purity Guarantee — full refund plus a free replacement if independent testing doesn't confirm our stated purity
Documentation
COA on every product page
A Certificate of Analysis is published on each product page and viewable before purchase.
