Meet Escozul.
Know the science.
Know the people.

A naturally occurring mixture of biologically active molecules produced by the Cuban blue scorpion. The species appears in the scientific literature as Rhopalurus junceus, also known as Heteroctenus junceus.

Its venom contains peptides, proteins and other components. Scientists study the whole venom, separated fractions and individual molecules to understand how each interacts with biological systems—including cancer-cell models.

This is why the exact material and experimental model matter: findings about one fraction or peptide do not describe every venom-derived product.

Our approach brings scientific research and personal support together. We investigate blue scorpion venom and its components while helping people understand our work, our product and the process of engaging with our team.

That combination—research, product information and accompaniment—defines how we work with our community.

Escozul® is Grupo LifEscozul’s product derived from blue scorpion venom. Ask our team for the formulation, ingredients and presentation available to you.

A specific U.S. presentation has a label published on DailyMed under NDC 87019-001-01. That record does not cover every formulation or presentation and is not FDA approval. Confirm the exact product with our team.

Escozul is the finished product. PBK2 is a peptide within a specific research line. The venom and fractions examined in laboratory studies are not interchangeable with the finished formulation.

Our team can explain the product information and the support services available to you.

In this research tradition, the term has a Cuban history and a specific scientific identity: Rhopalurus junceus, now known as Heteroctenus junceus, a species endemic to Cuba.

Cuban biologist Misael Bordier helped bring this research to international attention. A 2001 interview already used the Spanish term for blue scorpion venom. A 2011 scientific paper explicitly characterized the venom of the Cuban blue scorpion.

Presenting another species’ venom as though it were the venom studied in this Cuban research is misleading. The same name does not justify attributing findings obtained with one species to another.

Our venom samples have undergone chromatographic profiling at Tecnológico de Monterrey, the University of Chile and a laboratory in the United States.

This separates the sample’s components into a chemical fingerprint. Comparison with a reference using the appropriate method provides evidence of identity and consistency.

Ask our team about the sample tested, the laboratory and the analytical report. Analysis of a research sample does not automatically certify every bottle sold.

Ask for the scientific species name, the analytical report, the laboratory responsible and the identification of the sample or batch tested.

Also ask how those documents relate to the product you will receive. Trust should be supported by verifiable documents and product traceability.
