KEY INGREDIENTS of YEAH BUDDY™ Xtreme Pre-Workout Powder Energy Powder

Dynamine

Energy Focus

Dynamine™™ is the newest ingredient in high impact energy, mood and focus. Dynamine™™ is methylliber-ine, a purine alkaloid found in the kucha tea leaf. Dynamine™™ is known to amplify feelings of energy, mood and focus by activating receptors and other key neurotransmitters, inhibiting adenosine receptors, all without elevating heart rate or blood pressure.*

JUNIPER BERRY

INTENSE BOOST

150 mg of Juniper Berry per scoop - helps boost the caffeine to extreme levels.*

Caffeine

CAFFEINE ENERGY FOCUS

Caffeine is about as tried and true as it gets in the energy department. Everyone is aware of the energy and focus benefits from caffeine but caffeine has also been proven in studies to increase athletic per-formance. Yeah Buddy contains a strong 420mg dose of both fast acting and extended release caffeine to avoid the dreaded pre workout crash.*

Clarity Motivation

TeaCrine® is a patent-pending compound containing pure theacrine, which can be found in natural sources such as the Camellia assamica varkucha tealeaf, coffee and certain exotic fruits. A nature-identical compound, Tea Crine® delivers energy, mental clarity, and improved motivation and mood. It does not increase heart rate or blood pressure and is not a stimulant.*
