Built by Researchers,
for Researchers
Premium Peptides was born out of frustration with inconsistent compound quality in the research supply chain. Too many labs were receiving products with undisclosed impurities, missing documentation, or unreliable purity claims.
We set out to build a supplier that treats documentation as a first-class deliverable — not an afterthought. Every compound ships with a full Certificate of Analysis from an independent laboratory, and our internal QC team reviews every batch before it leaves our facility.
Research Credentials
Every compound we supply passes a rigorous multi-stage analytical verification process before it reaches your lab.
HPLC Purity Testing
Every batch undergoes high-performance liquid chromatography to verify compound identity and purity to ≥98%.
Third-Party COA
Independent laboratory Certificates of Analysis accompany every product — downloadable directly from each product page.
Mass Spectrometry
MS analysis confirms molecular weight and structural integrity, ruling out degradation or substitution.
Endotoxin Screening
LAL endotoxin testing ensures compounds meet research-grade sterility standards.
How We Ensure Quality
Synthesis & Sourcing
Compounds are synthesized or sourced from GMP-compliant facilities with full chain-of-custody documentation.
Internal QC Review
Our in-house team performs preliminary purity checks and visual inspection before forwarding to third-party labs.
Independent Lab Testing
HPLC, MS, and endotoxin testing are performed by accredited third-party laboratories with no affiliation to Premium Peptides.
