Storage and transport of research peptides

What this catalog declares

Every indexable technical sheet at Péptidos Colombia includes a storage condition: 2–8 °C, protected from light. It is the same figure already shown in the catalog's data block. A different temperature is not invented per compound: what does not come from a batch certificate of analysis is declared once and reused.

Physical form does follow the actual presentation. What is measured in volume ships as a solution in a vial; what is measured in mass or international units, as lyophilized powder in a vial. That distinction matters for transport and receiving, not for writing a laboratory protocol.

Cold chain at dispatch

Dispatch covers the national territory with a trackable waybill. In major cities, estimated delivery is 1 to 2 business days after dispatch; in the rest of the country, 2 to 4 business days. When the reference requires it, packaging keeps a cold chain. Times are counted from dispatch, not from the order date, and are confirmed in writing in the quotation.

The replacement guarantee covers transport damage or a wrong reference within the 48 hours following delivery. That is a commercial condition, not a statement about the batch's analytical integrity: that integrity is documented by the certificate of analysis.

What to check on receipt

A buying laboratory, on receipt, checks three things: that the packaging matches what was quoted, that the batch number matches the certificate of analysis, and that the vial shows no visible transport damage. If the certificate is missing or the batch does not match, the document provides no traceability. How to read that certificate is covered in this section's other article.

1. Identity of the reference and the quoted presentation.
2. Batch number on the vial and on the certificate of analysis.
3. Identifiable issuing laboratory on the certificate.
4. Record of the storage temperature declared by the supplier.

Frequently asked questions

Is every reference stored the same way?

This catalog declares 2–8 °C and light protection uniformly. A batch's specific temperature, if the issuer documents it, is stated in that batch's certificate of analysis.

Does shipping always use cold chain?

When the reference requires it. The written quotation confirms the packaging. The 1-to-2-business-day estimate for major cities and 2-to-4 for the rest of the country is counted from dispatch.

Does this article teach reconstitution or how to apply the material?

No. This site does not publish reconstitution steps or routes of administration. The material is sold for technical, research or laboratory use.
