Science you can trust.
Northern Aminos was founded by researchers who were tired of sourcing peptides from suppliers who couldn't prove what was in the vial. We built the standard we wished existed.
Precision at every step.
We believe the future of human performance and longevity research depends on one thing above all else: reliable source material. A peptide that isn't what it claims to be isn't just useless — it's a liability.
Every compound we carry is synthesized to pharmaceutical-grade specifications, independently tested by accredited third-party laboratories, and released only when it meets our internal purity threshold of 99.9% or higher.
How we verify every vial.
Synthesis to spec
All peptides are synthesized using solid-phase peptide synthesis (SPPS) under controlled conditions. Sequence fidelity is confirmed at the synthesis stage before any downstream processing.
HPLC purity analysis
Every batch undergoes high-performance liquid chromatography (HPLC) to quantify purity. We reject any batch that falls below 99.9% — no exceptions.
Mass spectrometry confirmation
Mass spectrometry (MS) confirms the molecular weight of each compound, verifying that the correct peptide was synthesized and no substitutions occurred.
Certificate of analysis
A full COA from an accredited independent laboratory accompanies every product. You can request the COA for any batch directly from our team.
Built for serious researchers.
Our catalog is curated around peptides with the strongest bodies of peer-reviewed research behind them. We don't chase trends — we stock compounds with documented mechanisms and reproducible results in the literature.
All research links open PubMed, the U.S. National Library of Medicine's database of peer-reviewed literature.
