Research Grade vs Pharmaceutical Grade
What research grade and pharmaceutical grade actually mean on a peptide label, why there is no single standard for them, and why the Certificate of Analysis matters more than the grade word.
What Is Net Peptide Content?
Net peptide content is the share of a vial's powder weight that is actually peptide, not the counter-ions, salts, and water. What it means, and why it isn't the same as purity.
What Is Lyophilized Powder? Why Peptides Are Freeze-Dried
Lyophilized means freeze-dried. What the dry form is, how the freeze-drying process works, and why research peptides are supplied as a powder rather than a solution.
How Research Peptides Are Tested
HPLC for purity, mass spectrometry for identity, and how the results become a per-batch Certificate of Analysis.
What "≥99% Purity" Really Means for Research Peptides
What a peptide purity percentage actually measures — how HPLC calculates it, and how purity differs from identity and net peptide content.
What Is Selank? A Research Overview
A synthetic tuftsin-derived heptapeptide studied in preclinical anxiety and neuroscience research — mechanisms, evidence, and limits.
How to Read a Peptide Certificate of Analysis (COA)
What identity, purity %, HPLC and batch fields mean — and what a COA can and cannot tell you.
Research Peptide Glossary — Purity, COA & Analytical Terms
Plain-language definitions of the terms on a Certificate of Analysis — purity, identity, net peptide content, HPLC, LC-MS, lyophilization and counter-ions.
