Peptides
you can trust.

Every lot is independently tested by ISO-17025 accredited U.S. labs using HPLC for identity and quantitation, plus LC-MS/MS for impurity profiling. Both reports are attached to the lot CoA — we publish the actual chromatograms, not summaries.

CoAs include identity match, assay value, total impurities, residual solvents, water content, endotoxin level, and bioburden — each with the test method and acceptance threshold. Our docs page walks through each field with worked examples.

Lyophilized vials are stable at 2–8°C for 24 months from the test date on the CoA. Once reconstituted, store at 2–8°C and use within 28 days. Avoid repeated freeze-thaw cycles.

Domestic orders placed before 2pm MT ship same-day via USPS Priority or UPS Next-Day Air, depending on temperature sensitivity. Most U.S. addresses receive in 1–3 business days.

Not currently. We ship to all 50 U.S. states and territories. International researchers can request a referral to a regional partner via our partner program.

Unopened product within 30 days, full refund. Damaged or temperature-compromised shipments: free reship, no return required. Detailed terms on the policy page.
