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.

Why Circulation Matters

Your cardiovascular system powers everything—from endurance to recovery. L-Arginine Plus helps increase nitric oxide for better blood flow, oxygen delivery, and total-body performance.

The Dual-Path Advantage

L-Arginine and L-Citrulline work together to support nitric oxide production. One acts fast, the other sustains results—so you feel the benefits longer.

Nutrients That Get Absorbed

We use AstraGin® to enhance amino acid uptake, so more of each dose actually gets used. That means better support for your heart, muscles, and blood vessels—without filler or waste.

What does L-Arginine Plus help with?

L-Arginine Plus supports circulation, cardiovascular health, stamina, and recovery by promoting nitric oxide production in the body.

When should I take it?

Take L-Arginine Plus once per day, ideally on an empty stomach or between meals, to support optimal absorption and nitric oxide production.

Will I feel it working?

Most users notice improved endurance, better recovery, and smoother energy throughout the day—but it’s designed to support long-term performance as much as immediate effects.

What makes L-Arginine Plus different from other circulation supplements?

It combines L-Arginine and L-Citrulline for fast and sustained nitric oxide support, and includes AstraGin® to enhance absorption—so your body uses more of each dose.

Can I take this with GROmuscle™?

Yes. They’re designed to work together. GROmuscle™ is a performance-driven pre-workout, while L-Arginine Plus supports daily circulation, vein health, and cardiovascular function.
