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.

All sales are final due to the nature of our research compounds. We do not accept returns, refunds, or exchanges.

If your order arrives damaged, contains the incorrect product, or does not match the listed Certificate of Analysis (CoA), please contact support@admin.calibratedlabs.com within 72 hours of delivery. After reviewing the issue, we will provide a replacement at no additional cost if the claim is verified.

If a shipment is lost in transit, is not marked as delivered by the carrier, or is delivered to an address different from the one provided at checkout due to a shipping or fulfillment error on our part, we will work with the carrier and, if necessary, provide a replacement at no additional cost.

Please note that customers are responsible for ensuring the shipping address entered at checkout is accurate. We are not responsible for orders delivered to an incorrect address provided by the customer.

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.
