A plain-language explanation of the Research Use Only (RUO) designation for peptides: what it covers, why it exists, and how it differs from FDA-approved pharmaceuticals.
Read GuideA field guide to the Certificate of Analysis that accompanies research peptides: what purity, mass spectrometry, HPLC, and identity data mean, and how to verify a COA.
Read GuideGeneral laboratory principles for storing, reconstituting, and handling lyophilized research peptides to preserve stability and integrity for in vitro work.
Read GuideHow research-grade peptides differ from pharmaceutical peptides in regulation, manufacturing, documentation, and permitted use, even when the chemical name is identical.
Read GuideWhat peptide purity means, how HPLC and mass spectrometry quantify it, why net peptide content differs from chromatographic purity, and why it matters for reproducible research.
Read GuideAn overview of the major research areas peptides are studied in — metabolic, tissue repair and recovery, growth and longevity, cognitive, and skin and cosmetic science.
Read GuideA research overview of the incretin-mimetic peptide class — GLP-1 and dual GIP/GLP-1 receptor agonists such as Semaglutide, Tirzepatide, and Retatrutide — and how they are studied.
Read GuideA research-context overview of BPC-157, one of the most studied peptides in tissue-repair research: what it is, the pathways it is studied in, and its Research Use Only status.
Read GuideA research overview of the growth hormone secretagogue class — GHRH analogues and ghrelin-receptor agonists such as Sermorelin, CJC-1295, and Ipamorelin — and how they are studied.
Read GuideA plain-language overview of solid-phase peptide synthesis (SPPS), why sequence fidelity and purification matter, and how synthesis quality shows up in a Certificate of Analysis.
