L-Arginine
L-Arginine is the direct precursor your body converts into nitric oxide — the signaling molecule that relaxes blood vessels for stronger, harder blood flow, plus better circulation and training pumps.
What It Is
L-Arginine is a conditionally essential amino acid and the primary substrate for nitric oxide synthase, the enzyme that produces nitric oxide (NO). GOMAXXX pairs 200 mg of L-Arginine with L-Citrulline, which together raise and sustain arginine availability more effectively than arginine alone.
Key Benefits
- ✓
Supports nitric-oxide production
Arginine is the raw material the body uses to make NO, the molecule that widens blood vessels.
- ✓
Supports stronger, harder blood flow
Healthy NO signaling underpins the blood flow behind sexual performance and confidence.
- ✓
Promotes circulation & pumps
Improved vasodilation also supports nutrient delivery to working muscle and fuller training pumps.
How It Works
Nitric oxide binds guanylate cyclase in vascular smooth muscle, generating cyclic GMP that relaxes the vessel wall and increases blood flow. A multicentre, double-blind, placebo-controlled trial found that long-term high-dose L-arginine improved vascular (blood-flow-dependent) function in men, and a meta-analysis reported arginine at 1.5–5 g improved outcomes versus placebo.
The Bedroom Benefit
Sexual performance depends on the same NO pathway that fuels a workout pump. By feeding nitric-oxide production, L-Arginine supports the blood flow behind harder, fuller performance and everyday confidence.
In GOMAXXX
Used as part of a circulation-focused amino pairing with L-Citrulline so NO support is both immediate and sustained.
