Frequently Asked Questions

What are Peptides?

Peptides are short chains of amino acids that function as precise biological signals. In laboratory settings, they are widely used to explore molecular pathways, model specific regions of proteins, and support assay development and method validation in research environments.

How does In Lab Peptides work?

In Lab Peptides provides research-use-only (RUO) peptides and bioregulators with a strong focus on consistency, documentation, and quality control. Our products are synthesized using established manufacturing methods and supported by independent third-party testing when available. Batch records and Certificates of Analysis (COAs) help confirm identity and purity to support reliable research workflows.

How fast do you ship?

Most orders are processed and shipped the next business day. Once shipped, U.S. domestic delivery typically takes 2–4 business days, depending on the carrier and destination. Tracking information is automatically provided as soon as your order leaves our facility.

How are your peptides synthesized?

Our peptides are produced using solid-phase peptide synthesis (SPPS), a gold-standard method in peptide manufacturing. This process enables precise sequence assembly and efficient purification to achieve high purity suitable for research applications. When applicable, third-party analytical testing and COA documentation are used to verify batch quality and integrity.

Do you provide Certificates of Analysis?

Yes. In Lab Peptides provides supporting documentation such as Certificates of Analysis (COAs) when available. These documents outline analytical results related to purity, identity, and quality control for each batch to support research validation.
