A beginner-friendly guide to how peptides work at a molecular level — covering receptor binding, signal transduction, major peptide categories, and bioavailability considerations for researchers.
A concise overview of retatrutide (LY3437943), the first triple GLP-1/GIP/glucagon receptor agonist to reach Phase 3 trials — covering its mechanism, key clinical data, and why it has captured the attention of metabolic researchers.
Cardiogen is a tetrapeptide bioregulator developed by Professor Vladimir Khavinson and the St. Petersburg Institute of Bioregulation. This guide covers its cardiac tissue specificity, mechanism of action in cardiomyocyte gene regulation, research findings on cardioprotection and myocardial repair, dosing protocols in preclinical studies, and comparison to other cardiac-relevant peptides.
A research-grounded overview of peptide safety: how peptides differ from pharmaceuticals, what the preclinical and clinical literature shows about side effect profiles, why purity and proper storage matter, and what certificate of analysis testing tells you about product quality.
NA Semax Amidate is a double-modified variant of Semax with N-terminal acetylation and C-terminal amidation, designed for enhanced metabolic stability and CNS penetration. This guide covers its mechanism, BDNF/NGF upregulation, melanocortin receptor interaction, research findings on cognition and neuroprotection, and how it compares to standard Semax.
NA Selank Amidate is a structurally modified Selank analog with N-acetylation and C-terminal amidation for improved metabolic stability. Research explores its anxiolytic, immunomodulatory, and neuroprotective properties.
Why does a 5mg vial of one peptide cost $40 while another costs $200? The answer lies in synthesis complexity, raw material costs, and the quality controls required at each production step.
What happens between checkout and your door? This guide covers NorthPeptide’s packaging standards, shipping timelines, customs handling, and what to do if something goes wrong.
Spills happen in any research setting. Here’s a practical guide to handling peptide spills safely — protecting your sample, your workspace, and yourself.
