US-based research peptide supply. Built on a single principle: every researcher deserves independently verified compounds with complete transparency on laboratory testing.
Official Peptides is a US-based supplier of research-grade peptide compounds. We supply 38 research compounds across eight categories: tissue repair, growth hormone secretagogues, cognitive and nootropic, anti-aging and longevity, immune and anti-inflammatory, metabolic, cellular signaling, and melanocortin peptides.
Every production batch is tested by independent third-party laboratories before fulfillment. Certificates of analysis are published and accessible for every batch, for every compound.
Purity claims in the research compound market are only meaningful when independently verified. We do not rely on manufacturer certificates alone. Every batch of every compound we supply undergoes HPLC analysis at an independent laboratory, with mass spectrometry identity confirmation. Results are published in full.
All compounds supplied by Official Peptides are intended strictly for in vitro laboratory research by qualified scientists. They are not approved by the FDA for human use, are not dietary supplements, and are not intended for diagnostic or therapeutic purposes.
