Never recieved product

Never recieved product and waisted two weeks anxiously waiting nothing. I was assured after I didn't receive my product the first time & after verifying my shipping info again and still no product. SO DISAPPOINTED. I was grasping at anything to motivate me to start getting back in shape hopefully starting with your highly advertised product instead it's been a let down and blow to my beginning

Quit being greedy!

Why ruin a good thing for your greed? Mandating that your customers elect from a recurring payment scheme is the lowest and grimiest of tactics. You lost a customer for life!

I like your product but being self employed some weeks i can only make 3 days a week

I like your product but being self employed some weeks i can only make 3 days a week. So the email option to skip a month was a great courtesy. As the rest of the world greed has struck your company. Changing to automatic charge and send is just not caring about the customer only your own pockets

Great product

I have been using this product for years. My blood pressure and cardiac tests have all been excellent. I will continue to L- Arginine Plus as long as I am here. I am now 71 yrs. young.

Fuel Every Layer of Performance

Your body runs on ATP, but energy alone isn’t enough. This bundle stacks NAD+ with nitric oxide support to unlock clean cellular output and endurance from the inside out—without relying on stimulants.

Circulation Meets Recovery

L-Arginine and Citrulline improve nitric oxide production, helping blood flow deliver oxygen, hydration, and nutrients where it counts—supporting stamina, muscle repair, and day-to-day performance.

Beyond the Pre-Workout Model

Most formulas flood your system with caffeine. This duo does more. It works with your body’s natural flow to improve performance and long-term health—not just today’s workout.

What makes this bundle different from standard supplements?

This stack goes beyond traditional pre-workouts or pump formulas. GROmuscle™ boosts performance through ATP production and blood flow, while L-Arginine Plus supports cardiovascular health, nutrient delivery, and long-term endurance. Together, they promote full-body output, faster recovery, and clean, daily performance without stimulant dependency.

What’s the “flush” sensation I feel?

That warm, tingling feeling is the NAD+ (niacin) flush. It means your blood vessels are opening, circulation is increasing, and the formula is actively delivering nutrients where your body needs them most.

Do I need to cycle on and off?

No. Neither product relies on harsh actives, so there’s no need to cycle. Both are safe for daily use when following the recommended serving.

When should I take each one?

Take GROmuscle™ immediately before your workout for an energy and performance boost. L-Arginine Plus can be taken daily, preferably between meals or on an empty stomach, to support blood flow and recovery.

Will I feel the effects right away?

GROmuscle™ kicks in within minutes—you may feel a warm “flush” sensation, signaling it's working. L-Arginine Plus supports long-term cardiovascular health and stamina; benefits are more noticeable with consistent use.
