Improved Peptides is a U.S.-based supplier of research-grade peptides operated by The Improved Company LLC in Oklahoma. Founded in 2026, the company focuses on providing lyophilized research peptides with independently verified testing, documented identity, and transparent batch-level information.
Improved Peptides describes its quality approach as “The Improved Standard,” centered on independent testing and verifiable documentation. Every production lot is tested by an independent third-party laboratory before release. Testing includes HPLC purity analysis and mass spectrometry identity confirmation, with results documented through batch-specific Certificates of Analysis (COAs). The company provides access to its COA Library so researchers can review available laboratory documentation for individual batches.
The store offers a catalog of lyophilized research peptides and compounds, including BPC-157, TB-500, GHK-Cu, Semax, Selank, Epitalon, and other research materials. Products are organized across research categories such as recovery, cognitive, metabolic, skin, longevity, growth, and sleep research.
Improved Peptides also maintains a Research Library featuring structured research overviews based on peer-reviewed literature, with citations linked to PubMed where original sources are available. The company provides educational resources covering peptide testing, Certificates of Analysis, HPLC, mass spectrometry, and other research-related topics.
