Choosing research peptides for laboratory work
Start with the exact compound, nominal vial quantity and supplied form required by your laboratory protocol. PhD Peptides product pages bring the specification and current batch documentation together, so you can review the material before ordering.
Where can I check the current batch report?
Use the batch summary and Certificate of Analysis tab on the product page, or search our COA Library. When your material arrives, match the vial code to the original report and retain a copy with your research records.
Does HPLC purity also tell me the peptide quantity?
These are separate results. Review the reported identity and purity alongside a quantity measurement where provided. Our purity versus quantity guide explains the distinction, and the COA guide works through a real PhD Peptides report.
How are the peptides supplied?
Our research peptides are supplied as lyophilised material in sealed, batch-coded laboratory vials. Follow the product-specific storage instructions. Explore the Research Articles for further guidance on analytical testing, material identity and laboratory handling.
