A complete reference guide to peptide categories, research terminology, quality markers and documentation standards used across the iPeptide catalogue.
What peptides are
Peptides are short chains of amino acids used in laboratory research to study signalling, molecular communication, stability, structure and biological pathway models. A peptide profile should be reviewed through measurable data such as identity, sequence, purity, storage requirements and batch documentation.
Recovery research peptides
BPC-157 and TB-500 are commonly reviewed in recovery-oriented research categories, including tissue-response and repair-model studies. For these peptides, laboratories typically focus on identity, sequence confidence, purity, storage conditions and COA availability.
Metabolic research peptides
GLP-1 related compounds, Semaglutide and Retatrutide are reviewed in metabolic and incretin-pathway research contexts. These products require careful attention to traceability, analytical consistency, storage guidance and batch-level documentation.
Longevity and copper peptide research
GHK-Cu and other copper peptide profiles are often discussed in longevity, cosmetic-biological and cellular signalling research. Documentation, handling sensitivity and a clear purity profile are important parts of responsible review.
How laboratories compare products
A useful peptide index helps teams compare products by category, technical profile and documentation status. The most important review points are product identity, purity, sequence, molecular weight, formula, storage instructions, COA availability and verification status.
Why documentation matters
iPeptide organizes product pages, COA links, verification tools and research profiles around traceability. The catalogue is built for laboratory review only, with no checkout, client login or consumer treatment workflow.
