From the lab
Practical notes on handling peptides well — storage, purity, documentation, and the analytical work that stands behind a result. Written for researchers, not patients.
Cold-chain shipping for research peptides
Why temperature in transit matters less than people fear for lyophilized peptides — and exactly what to check when a shipment lands so your material starts sound.
HPLC purity, in plain terms
What an HPLC purity number actually measures, why identity and purity are different questions, and how to read a chromatogram without being a chromatographer.
How to read a peptide certificate of analysis
A COA is only useful if you know what its numbers mean. Here's how to read identity, purity, and batch information — and the questions a good certificate should answer before you rely on it.
Storing and handling research peptides
Lyophilized peptides are stable, but only if they're kept and reconstituted with care. A practical guide to storage, reconstitution, and avoiding freeze–thaw damage in the lab.
