Black Mamba™ Epi with Epicatalean®: The Key to Next-Level Muscle Growth and Wellness

Elevate your fitness and well-being with Black Mamba™ Epi, now enhanced with Epicatalean®, a patented 90% Epicatechin formulation designed to deliver top-tier quality in every dose.


Why Epicatechin?

Found naturally in green tea and dark chocolate, Epicatechin is a powerful bioactive compound that, when optimized with Epicatalean®, can help you achieve your fitness goals faster and more effectively. It’s not just about the benefits of these superfoods—it’s about unlocking their true potential for your body.


The Science of Epicatalean®

Larger doses of Epicatechin target myostatin, the protein that limits muscle growth. Epicatalean® reduces myostatin levels while increasing follistatin, a protein that counteracts myostatin’s effects. The result? Black Mamba™ Epi helps remove the natural barriers to muscle development, providing a safer, more natural way to enhance your physique.

But there’s more—Epicatechin also reduces cortisol, the stress hormone that can hinder recovery, performance, and muscle gains. Each capsule delivers a potent 250mg of Epicatalean®, eliminating the need to consume sugar-heavy chocolate for similar benefits.


Benefits You Can Count On

  • Muscle Growth & Strength: Enhance protein synthesis for bigger, stronger muscles.
  • Fat Loss: Support a leaner, more defined physique.
  • No Hormonal Side Effects: Avoid the typical issues associated with prohormones or other compounds.
  • Improved Vascularity & Blood Flow: Boost nitric oxide levels for better recovery and performance.
  • Overall Health: Enjoy added perks like improved brain function, heart health, insulin sensitivity, and stress reduction.

Safe for Everyone

Designed for both men and women, Black Mamba™ Epi offers a versatile solution that requires no post-cycle therapy (PCT) or on-cycle support. It’s free from hormonal disruptions and won’t stress your liver, making it a smart choice for longer cycles and sustainable results.


How to Use Black Mamba™ Epi

  • Standalone Cycle: Take 1 capsule daily for 60 days (1 bottle).
  • Stacking: When combining with other compounds, stick to 1 capsule daily for consistent benefits.
  • For optimal results, take 2 capsules daily to maintain long-term improvements, with studies supporting doses of 150mg–200mg of Epicatechin for noticeable effects.

Why Wait?

Transform your fitness routine with Black Mamba™ Epi and Epicatalean®—a smarter, safer, and more effective way to amplify muscle growth, burn fat, and enhance overall health. Start your journey today and experience the difference.
