Frequently asked questions

Add any peptide to your cart and we add a second vial of the same compound and size at no charge. Every two vials of a product count as one paid and one free, so 2 vials cost the single-vial price, 4 vials cost double, and so on. The free vial is applied automatically in the cart, and the saving is shown on its own line.

Purity (HPLC) is the percentage of the sample that is the target peptide. Identity (LC-MS) confirms the measured mass matches the expected molecular weight. Net content is the actual peptide mass in the vial. Endotoxin, where tested, is reported in EU per mg.

Shipping within the United States is free on every order. Orders placed before 2 pm Eastern on a business day ship the same day; most deliveries arrive in 2 to 4 business days. Tracking is emailed as soon as the label is scanned.
