What “documented, tested, and traceable” actually means.
Not a marketing line — the specific methodology and testing behind every lot we ship.
Precision
Every compound is characterized against a public reference standard, not an internal spec sheet.
Integrity
We supply for legitimate research and business use only, and we don’t dress up unapproved compounds as consumer products.
Transparency
Every batch tested, every result available. Certificates of Analysis, molecular identifiers, and sourcing documentation are never withheld.
Consistency
The same testing methodology and documentation depth on compound one and compound thirty-seven.
Independent, third-party testing
Every lot is tested by Freedom Diagnostics, an independent third-party analytical laboratory — not self-certified in-house. Independent verification is the whole point: you don’t have to take our word for a result we produced ourselves.
What each Certificate of Analysis covers
Identity confirmation
Mass spectrometry (MS) and/or HPLC retention time matched against a reference standard, confirming the vial contains the labeled compound and not a substitute or analog.
Purity (HPLC)
Reverse-phase HPLC purity percentage, reported against the specification threshold for that compound.
Water content & residual solvents
Karl Fischer water content and residual solvent testing (GC), relevant to lyophilized peptide stability and shelf life.
Endotoxin & microbial count
LAL endotoxin testing and microbial count, reported in EU/mg and CFU/g against the lot specification.

The 61°N Standard
Nordvik draws its name and its discipline from the Norwegian fjord region around 61° North — where clean water, rugged coastlines, and uncompromising natural conditions leave no room for error. The 61°N Standard is our internal bar for what the four pillars above have to mean before a lot ships, applied without exception. If a compound can’t be independently verified, third-party tested, and fully documented back to its lot number, it doesn’t meet the standard, and it doesn’t leave our hands.
