Core Peptides supplies research peptides and peptide blends to laboratories, researchers and academic institutions in the United States. We have served the research community since 2019. Every product is synthesized and lyophilized in the USA and tested by an independent laboratory before it is released, and the certificate of analysis for each tested batch is published on the product page.
WHO WE ARE
Core Peptides is headquartered in Orlando, Florida. The company is run by a remote team dispersed in various locations across the United States, who oversee synthesis, quality control, customer support, and fulfillment. Scientific content on this site is written and reviewed by Dr. Dimitar Marinov, MD, PhD, Assistant Professor, Department of Hygiene and Epidemiology.
HOW EVERY BATCH IS TESTED
1. Synthesis: peptides are made by solid-phase peptide synthesis in the USA and supplied as lyophilized powder.
2. Independent testing: each batch is tested by Vanguard Laboratory, an A2LA-accredited US lab, using HPLC for purity.
3. Purity: only high-purity batches are released for sale. Our average peptide purity exceeds 99%, and is verified by HPLC for each tested batch. The exact result is shown on each tested batch’s certificate of analysis.
WHY RESEARCHERS CHOOSE CORE PEPTIDES
Researchers choose Core Peptides because we provide transparent, batch-specific documentation. You don’t have to rely on generic purity claims. You can review the available certificate of analysis for the batch you order, including HPLC purity results from an independent, A2LA-accredited laboratory. Questions?
