How do I track my order?

What is a lab report, and where do I find it?

Every batch is tested by an independent laboratory before it's sold, for identity (LC-MS) and purity (HPLC), and for endotoxins, sterility and heavy metals where listed. The report for the current batch is on each product page, and every published report is on the Lab reports page.

What purity can I expect?

Each product page shows the HPLC purity measured for the current batch, with the full report to download, so you can check the figure for the exact batch you receive.

How should I store peptides when they arrive?

Keep lyophilized (freeze-dried) peptides in their sealed vials in a freezer at about -20 °C, away from light and moisture. A few days at room temperature in transit is normal for lyophilized material. The storage notes on each product page give the details.
