Allmax Arginine 400g delivers pharmaceutical-grade L-Arginine in micronized powder form — the conditionally essential amino acid that serves as a direct precursor to nitric oxide (NO) production via the NOS (nitric oxide synthase) pathway. As an unflavored single-ingredient product, it gives athletes full control over their arginine intake: add it to a pre-workout for enhanced vasodilation, use it post-workout for growth hormone support, or take it fasted in the morning as a cardiovascular support supplement. 160 servings of 2.5g per 400g container.

Spec Per Serving
L-Arginine 2,500mg (2.5g)
Purity Pharmaceutical-grade L-Arginine
Servings per Container 160 servings (400g at 2.5g/serve)
Form Micronized powder (unflavored)
Other Ingredients None
  • Direct NO precursor via NOS pathway — L-Arginine is the substrate for nitric oxide synthase (NOS), the enzyme that produces nitric oxide from arginine; NO relaxes blood vessel walls, increasing blood flow and delivering the classic "pump" effect during training
  • Growth hormone secretagogue — fasted use — arginine taken on an empty stomach (typically 30–60 minutes pre-sleep or upon waking fasted) has been shown in research to stimulate growth hormone secretion; athletes interested in GH support use arginine in fasted states separate from meals
  • Flexible dosing — 2.5g or stack multiple scoops — the 2.5g scoop allows precise control; many athletes use 3–5g pre-workout for pump support or 2–4g fasted for GH applications; 160 servings at 2.5g provides extensive dosing flexibility
  • Stacks with citrulline for enhanced NO — L-Citrulline is converted to L-Arginine in the kidneys with better bioavailability than oral arginine; stacking both provides a sustained NO precursor supply; arginine adds direct substrate while citrulline replenishes the pool over time
  • Canadian-grade quality — 400g economy size — Allmax pharmaceutical-grade arginine with GMP certification and Health Canada NHP compliance; 160 servings per container at competitive cost per gram

Best for: Athletes who want to add arginine to a pre-workout for pump enhancement; those using arginine for its growth hormone-stimulating properties in fasted states; cardiovascular health applications where NO support is a goal.

Not ideal for: Those expecting arginine alone to produce dramatic pre-workout pumps (oral arginine has moderate bioavailability; citrulline is generally superior for pre-workout pump use due to better absorption and kidney-to-arginine conversion); individuals with herpes simplex infections (arginine can exacerbate outbreaks — consult a physician).

Ingredients: 100% L-Arginine (pharmaceutical grade). No other ingredients. Allergen Info: Vegan, gluten-free, dairy-free, soy-free. GMP-certified. Suggested Use: Mix 1–2 scoops (2.5–5g) with 250ml water. For pump support: take pre-workout. For GH support: take fasted, 30–60 minutes before sleep or upon waking. Do not take within 2 hours of a protein-rich meal for fasted GH applications.

Who Is This For?

Allmax Nutrition amino acid supplement is ideal for athletes and gym-goers looking to support specific performance and recovery goals. It works well as part of a stack alongside protein, pre-workout, or as a targeted recovery supplement on training days.

Who Is This NOT For?

Not a standalone supplement for muscle building — specific amino acids work best as part of a comprehensive nutrition plan. Consult a healthcare professional before use if you have pre-existing medical conditions.

Frequently Asked Questions

What does L-Arginine do for athletic performance?
L-Arginine is a direct precursor to nitric oxide (NO) in the NOS enzyme pathway. Nitric oxide relaxes and dilates blood vessel walls, increasing blood flow to working muscles — producing the 'pump' during training and improving nutrient and oxygen delivery. Arginine is also used in fasted states because research shows it can stimulate growth hormone secretion when taken on an empty stomach, away from insulin-elevating foods.
Is L-Arginine or L-Citrulline better for pre-workout pumps?
L-Citrulline generally produces better pre-workout pump results than oral L-Arginine because citrulline has significantly higher oral bioavailability. Arginine taken orally is metabolized substantially in the gut and liver before reaching the bloodstream, while citrulline bypasses this first-pass metabolism, converts to arginine in the kidneys, and sustainably raises plasma arginine levels. Many pre-workouts include both: citrulline as the primary pump agent and arginine for additional direct substrate. Allmax Arginine can be stacked with a citrulline-containing pre-workout for this combined effect.
How many servings are in Allmax Arginine 400g?
At the 2.5g scoop size, the 400g container provides 160 servings. At 5g per day (two scoops), it provides 80 servings — approximately 2.5 months of use.
When should I take L-Arginine for best results?
For pump support, take 2.5–5g 30–45 minutes before training. For growth hormone-stimulating effects, research uses 2–4g on an empty stomach — typically first thing in the morning (fasted) or 30–60 minutes before sleep. For GH applications, avoid taking arginine within 2 hours of a protein-rich meal, as elevated insulin and amino acids from the meal reduce the GH response.
Is Allmax Arginine available from an authorized retailer in Canada?
Yes. Bulldog Nutrition is an authorized Canadian and US retailer of Allmax Nutrition. Allmax is a Canadian supplement brand manufactured to Health Canada NHP standards — products are sourced directly and shipped fast across Canada and the United States.
