Who We Are

Core Peptides is a U.S.-based research peptide supplier with over three years of experience serving laboratories, independent researchers, and scientific institutions across the United States and internationally. Founded on a commitment to quality and transparency, we have built our reputation by supplying research-grade peptides that meet the rigorous standards today’s scientific community demands.

We are not a compounding pharmacy. We are a dedicated chemical supplier focused exclusively on the research and laboratory market — a distinction we take seriously in everything we do, from sourcing to fulfillment.

Our Mission

Our mission is straightforward: to make high-purity research peptides accessible, affordable, and reliably delivered to researchers who need them. We believe that quality should never be compromised, and that every researcher deserves a supplier they can trust order after order.

Why Researchers Choose Core Peptides

✔ cGMP-Certified Manufacturing

Every peptide in our catalog is produced in current Good Manufacturing Practice (cGMP) certified facilities. cGMP standards govern the conditions under which pharmaceutical and research-grade compounds are manufactured, ensuring consistency, purity, and safety in every batch we ship.

✔ Third-Party Lab Tested

We do not rely solely on manufacturer certificates. Our products undergo independent third-party laboratory testing to verify purity and composition. This gives our customers confidence that what is on the label matches what is in the vial.

✔ Fast USA Delivery + Worldwide Shipping

We offer overnight delivery within the United States and international shipping within 3–5 business days. Our fulfillment process is streamlined to minimize delays, because we understand that research timelines matter.

✔ Wide Product Range

From popular research peptides like Retatrutide to specialized compounds, our catalog is continuously updated to reflect the evolving needs of the research community. If you are looking for a specific peptide not currently listed, contact us — we are happy to help.
