HR Labs Defib

DEFIB Pre-Workout

A complete performance formula built for intensity, drive, and output

DEFIB is designed for sessions where you need more than just a caffeine hit. It combines high-dose performance ingredients with a layered focus and energy system to support strength, endurance, and concentration throughout your workout.

Instead of leaning heavily on stimulants, the formula is built around proven training compounds like citrulline, beta-alanine, and betaine, supported by nootropics and caffeine to help maintain both physical output and mental sharpness from start to finish.

Whether you're pushing volume, intensity, or heavy lifts, DEFIB is structured to support consistent performance across the entire session.

What sets it apart

• Clinically aligned doses of key training ingredients
• High-performance blend targeting strength, pumps, and endurance
• Integrated nootropic support for focus and drive
• Designed for full-session performance, not just short bursts
• Available in multiple flavour options

Where it fits

Use DEFIB when your training demands:

• Sustained strength and power
• High work capacity and endurance
• Strong mental focus and engagement
• Increased blood flow and muscle pumps

How the formula works

Rather than relying on stimulants alone, DEFIB is built around three core areas:

• Performance output – ingredients like citrulline, beta-alanine, and betaine support strength, endurance, and training volume
• Energy system – caffeine provides alertness without being the sole driver of the formula
• Cognitive support – nootropics help maintain focus, drive, and mental clarity during demanding sessions

This structure allows for a more balanced and reliable pre-workout experience.

• Lifters training with high intensity or volume
• Those wanting more than just a stimulant-heavy pre
