The Improved Standard
Research-grade peptides, independently tested on every lot. Verifiable purity. Documented identity. Transparent sourcing.
About Improved Peptides
The Improved Company LLC, operating as Improved Peptides, was founded in Oklahoma in 2026 by a team committed to a single proposition: research peptide supply with verifiable testing on every batch.
Improved Peptides supplies lyophilized research peptides — including widely studied compounds such as BPC-157, TB-500, GHK-Cu, Semax, Selank, and Epitalon — strictly for laboratory research use only. Improved Peptides products are research compounds. They are not drugs, supplements, or foods. They are not intended for human or animal consumption.
What “The Improved Standard” Means
Every production lot is independently tested before release. The current laboratory partner is Freedom Diagnostics Testing, which performs HPLC purity analysis and mass-spectrometry identity confirmation on every batch. Results are documented in batch-specific Certificates of Analysis.
Batch-specific Certificates of Analysis for current production lots are accessible via the COA Library; additional batches available on request.
The full testing methodology, sample-handling protocols, and analytical specifications are documented at our Testing Standards page.
Research Library
The Improved Peptides Research Library publishes structured research overviews summarizing peer-reviewed literature on each compound in the catalog. Articles are prepared by the Improved Peptides Research Team and citation-linked to PubMed where original sources are available.
The library exists to give researchers and procurement scientists a single point of reference for what is and isn’t established in the literature on each compound under study.
