Common Questions.

Everything you need to know about our synthesis process, laboratory verification protocols, and research utility.

How are Calibrated Labs compounds manufactured?

All compounds are produced via solid-phase peptide synthesis (SPPS) by partner facilities specializing in research-grade peptide production. Each batch undergoes independent third-party HPLC and LC-MS verification before release, with chain-of-custody documentation maintained from synthesis through fulfillment. Manufacturing source and applicable certifications are disclosed on each batch-specific CoA.

Due to the nature of research compounds, all sales are final once a vial seal is broken. Unopened products may be returned within 14 days of delivery for a full refund, less return shipping. If a shipment arrives damaged, mislabeled, or with a discrepancy against the listed CoA, contact support@calibratedlabs.com within 72 hours of delivery for a no-cost replacement.

Every product ships with a batch-specific CoA documenting purity (HPLC), mass verification (LC-MS), and test date. CoAs are also accessible through the Calibrated Labs research portal, indexed by the batch number printed on each vial. Historical CoAs remain available for cross-referencing and audit purposes.
