The Active Ingredient Is: Turkesterone (Ajuga turkestanica Extract)

Turkesterone is a natural ecdysteroid compound usually sourced from Ajuga turkestanica. It is thought of as an active supplement ingredient aimed at supporting exercise-related adaptation.

This form comes from Ajuga turkestanica and is shown as a high-purity extract in this product.

What Does Turkesterone Do?

Turkesterone works through ecdysteroid pathways to take part in cellular processes that may help muscle adaptation to training. Studies suggest these mechanisms can support protein synthesis in skeletal muscle and perhaps boost performance-related outcomes.

In normal physiology terms, this ingredient helps the body respond to training stresses as part of a balanced fitness routine.
