Certified PEP MEX Expands Its Reach in Mexico With Two New Research Peptide Websites
Nov 7, 2026
Péptidos Verificados brings the full catalog together for online purchase, while Péptido Retatrutida focuses on a molecule as it rounds out its Phase 3 program.
Mexico City, Mexico, November 7, 2026 -- Mexico City, Mexico, 7th November – Certified PEP MEX is a research peptide company that supplies research-use-only (RUO) compounds, and today it announced it is expanding its reach in Mexico with two new websites: Péptidos Verificados at https://peptidosverificados.mx/, where every item in the catalog is available for purchase, and Péptido Retatrutida at https://peptido-retatrutida.mx/, which focuses specifically on retatrutide.
The announcement comes as interest in research peptides continues to grow in the country. Péptidos Verificados brings together 39 compounds in 48 presentations, each with a batch-specific certificate of analysis (COA) and FedEx shipping across Mexico from the official store at https://certified-peptidos.mx/. Péptido Retatrutida offers detailed information on the triple-receptor molecule just as its clinical development approaches a key regulatory stage.
“More and more researchers in Mexico are looking for peptides with documentation they can verify for themselves, and we wanted to give them one clear site with the full catalog and another dedicated to retatrutide as it rounds Phase 3,” said Benson Jamison of Certified PEP. “Every vial carries a QR code that opens the lab report for its batch.”
What Each Site Offers
- Péptidos Verificados presents the full catalog with a product page, presentation and batch COA for every compound, a dedicated GLP collection, a Spanish-language research library and local pages for sixteen Mexican cities. Every product can be purchased directly on the site, with payment in Mexican pesos.
- Péptido Retatrutida centers on retatrutide (LY-3437943), a triple agonist of the GLP-1, GIP and glucagon receptors. It includes batch specifications, the COA issued by Vanguard Laboratory, and guides to reading a certificate of analysis and comparing the molecule with tirzepatide and semaglutide.
Prices and availability may change without notice.
Retatrutide: Phase 3 Enters the Home Stretch
On July 23, 2026, Eli Lilly announced positive results from the Phase 3 TRIUMPH-2 and TRIUMPH-3 trials, bringing the total to five positive Phase 3 studies for retatrutide. The company plans to submit a Biologics License Application (BLA) to the FDA in the first quarter of 2027.
Retatrutide remains an investigational compound and is not approved as a medicine by the FDA or COFEPRIS. The material offered by Certified PEP MEX is a research-grade compound, distinct from the pharmaceutical product used in clinical trials, and is sold strictly for laboratory use. None of the clinical results mentioned constitute claims about Certified PEP MEX products.
Quality and Transparency
Certified PEP MEX peptides are manufactured in the United States in a cGMP-compliant facility and tested by independent laboratories, most often Vanguard Laboratory in Olympia, Washington, which is accredited under ISO/IEC 17025:2017. Every batch has its own COA, and the QR code on each vial opens the report directly on the testing laboratory’s own website.
Research Use Only: Certified PEP MEX products are intended solely for in-vitro laboratory research and are not intended for human or veterinary use, consumption, clinical use, diagnosis, treatment or prevention of disease. No dosing or administration information is provided. Statements in this release have not been evaluated by the U.S. Food and Drug Administration or by COFEPRIS in Mexico.
