Quality Assurance
Our commitment to pharmaceutical-grade purity and rigorous testing standards ensures researchers receive the highest quality peptides for their studies.
All peptides undergo HPLC analysis to verify minimum 98% purity, with most batches exceeding 99% purity standards.
Certificate of Analysis provided with each batch, documenting purity, molecular weight, and identity verification.
Manufactured in current Good Manufacturing Practice facilities with ISO 9001:2015 certification.

cGMP Compliance
All peptides are synthesized in facilities operating under current Good Manufacturing Practices (cGMP) as defined by regulatory authorities. This ensures consistent quality, proper documentation, and validated manufacturing processes.
Solid-Phase Peptide Synthesis (SPPS)
Peptides are synthesized using automated SPPS with Fmoc chemistry, providing high yield and purity. Each synthesis is followed by HPLC purification to remove truncated sequences and side products.
Quality Control
Multi-stage quality control includes in-process testing, final product analysis, and stability studies. Only batches meeting all specifications are released for distribution.
Storage & Handling
Peptides are lyophilized (freeze-dried) and stored at -20°C to maintain stability. Products are shipped with cold packs to ensure temperature control during transit. Proper storage extends shelf life to 2-3 years.
In addition to manufacturer testing, select batches undergo verification by independent third-party laboratories to ensure unbiased quality assessment. Third-party testing includes:
Independent HPLC Analysis
Purity verification by accredited analytical laboratories using validated methods
Mass Spectrometry Confirmation
Molecular weight and identity verification by independent MS facilities
Microbial Testing
Sterility and bioburden testing to ensure product safety for research applications
Heavy Metal Screening
ICP-MS analysis to verify absence of heavy metal contamination
