At The Core Of Our Science-Backed Formula

A caffeine metabolite that delivers steady, crash-free energy.

L-Citrulline (6G)

L-Theanine (200mg)

An amino acid found in tea that promotes calm focus for a smooth energy delivery.

Citicoline (250mg)

A nootropic compound that improves focus, clarity, and mind-muscle connection.

Pine Bark Extract (200mg)

Boosts nitric oxide production for enhanced vascular support.

Built With Purpose. Dosed to Perform.
