HERO Ingredient

Fenugreek Extract
(Testosurge®)

Fenugreek has been shown in clinical studies to help naturally support healthy testosterone levels. This can contribute to better strength, energy, and overall vitality.

High T® Black uses Testosurge®, a highly potent form of fenugreek extract to ensure consistent quality and effectiveness, along with Ashwagandha and Boron to gently support the body’s own hormone balance.

HERO Ingredient

L-Citrulline

L-Citrulline is a natural amino acid that helps the body increase nitric oxide levels. Nitric oxide plays an important role in improving blood flow, helping more oxygen and nutrients reach the muscles during physical activity.

With better circulation, your body can perform for longer with less strain, supporting greater stamina and endurance during workouts or daily movement.

It also helps reduce post-exercise fatigue, promoting quicker recovery so your muscles can rebuild, restore, and feel ready for what comes next.

High T® - Your Source of

Strength

High T® helps support natural testosterone levels, which are important for muscle strength and tone. With regular use, your body can feel stronger and more capable during workouts and daily activity. It helps you move with confidence and feel more in control of your physical performance.

Energy

When testosterone levels dip, it can affect how energetic and motivated you feel. High T® helps maintain healthy levels to support steady energy throughout the day. You may notice improved focus, better mood, and a sense of being ready to take things on.

Endurance

Strength is one thing, being able to keep going is another. High T® supports stamina, helping you stay consistent during workouts or any physical activity. It helps reduce that early burnout feeling, so you can finish strong, not just start strong.

Recovery

High T® supports increased nitric oxide, which helps improve blood flow to your muscles. This can mean less tiredness during workouts and quicker recovery afterward. Your body gets the support it needs to repair, rebuild, and get ready for the next day.
