Thymogen Alpha-1 is an oral peptide supplement that contains two synthetic dipeptides: Glu-Tryp (commonly known as Thymogen) and Lys-Glu. These components have been examined in scientific literature for their biological properties. The formulation is offered in a shelf-stable, enteric-coated capsule to help protect the ingredients during digestion. Thymogen Alpha-1 is independently third-party tested for purity and is free from gluten, dairy, soy, magnesium stearate, heavy metals, and microbial contaminants.
