Your peptide shipment arrives. Before opening the vials or starting an experiment, take a few minutes to check what was delivered and what instructions came with it. A simple receiving record can prevent confusion later.
1. Match the label to the order
Check the product name, stated form, quantity, number of containers and batch number against the order. For a custom peptide, also check the agreed sequence and modifications. A similar name does not always describe the same material.
A packing example: an order for four vials of 5 mg should list four containers and a total stated amount of 20 mg. That checks the packing arithmetic; it does not verify the actual mass or peptide content inside each vial.
2. Photograph and record the condition on arrival
Record the arrival date and time. Photograph the outer packaging, container labels and any visible damage or leakage. Save the carrier tracking record and temperature-logger file if one was included.
Write down observations rather than conclusions. “The outer box was warm to the touch” is an observation. “The peptide is damaged” requires evidence that a receiving photo alone cannot provide.
3. Shipping conditions and storage instructions are different
Bachem describes different conditions for short-term handling, long-term storage and peptides in solution. For example, its general guide mentions below −15 °C for longer storage of lyophilized peptides and colder conditions for long-term storage. These are attributed background examples, not a storage specification for every NHD product.

Use the instructions agreed for the exact product and batch. Do not decide whether a shipment is acceptable by comparing the delivery temperature with the freezer temperature alone.
To assess a temperature excursion, meaning time outside the agreed transport range, the supplier needs the temperature, duration, material form, packaging and applicable stability information. Appearance alone cannot show that purity or activity has been preserved.
4. Keep dry material and prepared solution separate in your records
Lyophilized means freeze-dried. Instructions for a sealed dry vial do not automatically apply once the material is dissolved. Ask for the appropriate solvent, storage conditions and supported holding time for your planned laboratory use.
Bachem warns that moisture uptake can affect content and stability. Follow the product-specific handling instructions when opening cold containers, and record when the vial was opened or a solution was prepared.
5. Keep a short receiving checklist
Product and form: ____; batch: ____; container count and stated amount: ____; arrival date/time: ____; packaging observations: ____; transport records: ____; document references: ____; storage instruction and source: ____; unresolved questions: ____.
If a label does not match, a seal is damaged or essential instructions are missing, keep the material identified and separate from accepted stock while the discrepancy is reviewed under your laboratory procedure. Contact the supplier with the records rather than guessing.

6. Confirm requirements before the next shipment
For a GHK-Cu or LL-37 inquiry, send the exact product link and destination, and ask which storage instructions, shipment conditions and batch records can be provided. Confirm requirements before agreeing the order.
