A lot of supplement marketing describes a formula in broad strokes. The Supplement Facts panel is where the real, checkable details live.
Seven ingredients, each with its own disclosed milligram amount: Niacin 7.5mg, Calcium 18mg, L-Arginine 200mg, L-Arginine AKG 2:1 Extract 200mg, L-Citrulline HCl 100mg, L-Citrulline Malate 100mg, and Beta-Alanine 40mg.
A disclosed milligram amount lets you compare a formula against published research on that specific ingredient — something a vague "proprietary blend" never allows.
Serving size, servings per container, other (inactive) ingredients, storage instructions, and distributor contact information are all printed directly on the label — read it before your first capsule.
Before ordering any supplement, look for the actual label rather than relying on a sales page's summary of it.
