Same-Day Fulfillment
Orders placed by 2pm ET ship the same day from our U.S. facility. Discreet packaging, tracking by SMS.
First batch reports coming soon
Every Core Labs batch is HPLC and mass-spec tested at our analytical lab. The first published reports will appear at launch.
Browse compounds →Most peptide suppliers ship in clear glass. We don't.
UV light can degrade peptide amino acids over time, particularly under continuous office lighting. Medical-grade amber blocks ~99% of UV light vs. only ~10% for clear glass. Amber glass is widely used for light-sensitive pharmaceutical and laboratory materials — we use it because the data your research depends on deserves packaging built for stability.
