Thermogenic support, Energy and focus, Metabolic support
Adults with high-energy training routines seeking focused energy and thermogenic support, or people following a calorie-conscious plan looking for added metabolic support.
Assess tolerance: Day 1 take 1 capsule once daily; Days 2–3 take 2 capsules once daily; Day 4 and beyond take 2 capsules twice daily 30–60 minutes before your two largest meals, not within 5 hours of bedtime; do not exceed 4 capsules per day. Avoid other caffeine or stimulants, and consider taking with water and food if stomach sensitivity occurs.
Caffeine blocks adenosine receptors and increases catecholamines, which may boost energy expenditure and alertness.
Caution: High caffeine may cause jitters, rapid heartbeat, or sleep disruption, especially if combined with other stimulants or taken late in the day.
Chlorogenic acids may influence carbohydrate metabolism and support fat use by modulating glucose absorption and related enzymes.
Caution: Contains natural caffeine sources and may increase sensitivity to stimulants; reduce other caffeine intake if you feel overstimulated.
Yohimbine blocks alpha-2 adrenergic receptors, which may increase norepinephrine activity and promote fat mobilization.
Caution: Stimulant effects may raise heart rate, blood pressure, or anxiety; avoid other stimulants and discontinue if uncomfortable effects occur.
L-theanine modulates neurotransmitters like GABA and dopamine, which may promote calm focus and temper stimulant-related jitteriness.
Caution: May cause drowsiness in some individuals; monitor how you feel when combining with caffeine.
Capsaicinoids may increase thermogenesis by activating TRPV1 receptors and supporting calorie burn.
Caution: May cause gastrointestinal warmth or discomfort; take with water and avoid if spicy foods bother you.
Caffeine and yohimbine act on adrenergic pathways to elevate energy and mobilize fat, while chlorogenic acids from green coffee focus on carbohydrate metabolism. L-theanine helps smooth stimulant intensity for sustained focus, and cayenne adds thermogenic support through TRPV1 activation.
Label Warning: Not for persons under 18. Do not use if pregnant or nursing. Stop use and consult a medical doctor if you experience unusual symptoms. Consult a medical doctor before use if you have been treated for, diagnosed with, or have a family history of any medical condition, or if you use any prescription or over-the-counter drugs. Each serving contains caffeine comparable to about 3.5 cups of coffee; caffeine-sensitive individuals may experience restlessness, nervousness, tremors, headache, anxiety, palpitations, increased heart rate, or trouble sleeping. Do not combine with other sources of caffeine or stimulants. Consult a medical doctor before starting any diet or exercise program. Do not exceed the recommended serving. Use only as directed.
Who should be cautious: People with heart concerns, high blood pressure, anxiety, sleep issues, or sensitivity to stimulants may need extra caution. Those with liver or kidney issues, or gastrointestinal conditions may also wish to discuss with a healthcare provider. Individuals taking medications for blood pressure, heart rhythm, mood, attention, or other stimulants should consult a healthcare provider. Because this product contains caffeine and yohimbe, discuss with a healthcare provider before combining with medications that may interact.
Storage: Store in a cool, dry place between 60°F and 80°F.
