FAQ
Have a question?
What does peptide purity mean?
Purity is the share of a sample that is the intended peptide sequence, as measured by HPLC. Higher purity means fewer unknown variables in a laboratory experiment.
Why are research peptides supplied lyophilized?
Freeze-drying removes water, which helps a peptide stay stable in storage and transit until a laboratory is ready to reconstitute it for analysis.
How should vials be stored on arrival?
Keep sealed vials cold, dry and away from light. Lot-specific storage notes appear on the label and certificate of analysis.
What should I check before ordering?
Look for third-party HPLC and mass spec data, a lot number that matches a published certificate, and a supplier that sells for research use only.
Why does batch documentation matter?
Documentation lets you trace each vial to its test results so your methods section and data can be reproduced and audited.
What is the difference between a single peptide and a blend?
A single peptide contains one sequence. A blend combines two sequences in one vial, and each is identified in the lot's test report.
Are blends tested to the same standard?
Blends are documented the same way as single peptides. Test reports are published on our COA page as they become available.
Are your products for human use?
No. For research use only. Not for human consumption. We do not provide dosing, administration or usage guidance of any kind.
