How are research peptides shipped and checked on arrival?

No. Packaging and temperature controls should reflect the material's documented stability and shipping requirements. A dried sample and a prepared solution may need different arrangements. Ask the supplier for the product-specific shipping and storage instructions before placing an order.

This article describes general laboratory receiving practices, not ENOS Labs USA shipping, delivery or replacement policies. Do not infer suitability from the presence or absence of a cold pack alone; evaluate the requirements for the particular material.

Compare the shipment with the order and accompanying documents. Check material names, vial counts and lot identifiers. Look for visible damage, broken seals, leakage or labels that cannot be read. Record discrepancies before discarding the outer packaging.

If a validated shipment includes a temperature indicator or logger, review it according to the acceptance procedure. The condition of a cold pack at delivery is not a complete record of transit temperature. An unexplained excursion requires assessment rather than an assumption that the material is unaffected.

Move accepted material promptly to the storage conditions specified for that product. Retain the COA and receiving record with the lot information. Do not open a vial merely to inspect the powder if doing so would expose it unnecessarily to moisture or contamination.

For damage, missing documentation or an uncertain temperature history, keep the material segregated under appropriate storage conditions and contact the supplier. Resolve the issue against the laboratory's acceptance criteria before releasing it for experimental work. Avoid making a replacement or refund assumption without the supplier's actual policy.
