Love It

I have been using the Gromuscle for a while. I took a break and tried a couple of others and quickly came back to Gromuscle. I used to buy it in the silver bag and pick it up from Joe's house.

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

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.
