Frequently Asked Questions
Common questions about our research peptides and quality standards
What purity standards do your peptides meet?
Every batch is targeted at greater than 98% purity by HPLC, with identity confirmed by mass spectrometry. Your Certificate of Analysis lists the measured purity and methods used for that specific batch.
How are peptides stored and shipped?
Lyophilized peptides are stored under controlled conditions and shipped to preserve stability. We recommend storing sealed vials at −20°C for long-term storage or 2–8°C for shorter periods, and following your lab’s SOPs after reconstitution.
What documentation is provided with each order?
Each shipment includes a batch-specific Certificate of Analysis summarizing purity, identity, and other applicable test results. Additional documentation may be available through your order history or by contacting support.
What is your quality control process?
Batches are produced under documented protocols and analyzed by independent U.S. laboratories using methods such as HPLC, mass spectrometry, and additional tests as appropriate. Only batches that meet our acceptance criteria are released.
Are your peptides suitable for in vivo research?
Our products are sold strictly for research use by qualified investigators. Suitability for any protocol—including in vivo work—is determined by the researcher and their institution; we do not make therapeutic or clinical claims.
