GROmuscle™
What is GROmuscle™ and how does it work?
GROmuscle™ is a powerful pre-workout that is not dependent on stimulants, designed to improve energy, blood flow, and performance using NAD+ and ~100mg of caffeine per serving. You’ll feel it working within minutes—especially through the signature NAD+ “flush,” a warm, energized sensation caused by burning the toxins from your cells for energy.
What’s the “flush” sensation I feel?
That’s the NAD+ doing its job. It signals increased blood flow to the capillaries, helping deliver oxygen and nutrients to your muscles more efficiently. It’s temporary and totally normal.
Do I need to cycle off GROmuscle™?
No. GROmuscle™ is designed for daily use and does not require cycling or loading phases.
What makes GROmuscle™ different from typical pre-workouts?
Most pre-workouts are fueled by 200-400mg of caffeine per serving. Caffeine can hinder nourishment from leaving the arteries and veins, thereby preventing muscles from getting proper nutrients and negatively affecting performance and recovery. At only approximately 100mg of caffeine per serving, GROmuscle is powered by blood flow, not artificial stimulants. Niacin (NAD+), not caffeine, is our primary driver. The NAD+ in GROmuscle facilitates blood flow beyond just the arteries and veins, flooding the capillaries with the nutrient-rich blood required by muscle tissue for optimum performance. The almost immediate result is a euphoric energy surge you can feel and a NAD+ skin “flush” you can literally see.
Can I take GROmuscle™ even if I’m not working out?
Yes. Many people use it for long workdays, focus-driven tasks, or low-intensity activity. It supports mental clarity and energy without the crash.
Is GROmuscle™ safe for athletes?
Yes. All ingredients comply with WADA, NCAA, and NFL banned substance guidelines, and the product is manufactured in an NSF-certified facility.
Suggested Use
Mix one packet with 8 oz. of water and take immediately before workout. For best results, use on an empty stomach.

What does L-Arginine Plus help with?
L-Arginine Plus supports circulation, cardiovascular health, recovery, and stamina by promoting nitric oxide production in the body. It’s a stimulant-free formula designed for daily use.
When should I take it?
You can take L-Arginine+ daily, ideally before activity or training. It also stacks well with GROmuscle™ for enhanced blood flow and performance.
Will I feel it working?
Unlike GROmuscle™, L-Arginine+ has no flush or stimulant effect. Most users notice improved stamina or recovery during cardio or endurance-based activity.
Suggested Use
