Product score

59.1 / 100Good

Category average: 66.2 / 100

The label claims substantial arginine and citrulline amounts, but its 2.7 g serving size cannot contain even the stated 5.11 g of arginine. Treat the dose as unresolved and seek clarification before relying on the product.

Scoring criteria

Quantity
75 / 100
The claimed 5.11 g arginine amount would be a substantial supplemental dose, but it conflicts irreconcilably with the 2.7 g serving size, leaving the actual dose uncertain.
Form
75 / 100
The identified L-arginine is a conventional amino-acid form with no established relevant absorption or tolerability advantage over ordinary alternatives.
Convenience
100 / 100
The directions specify one scoop per day; each scoop is one measured powder portion, with about 30 portions per container.
Label accuracy
25 / 100
The stated 2.7 g serving cannot contain the declared 5.11 g of arginine alone, making the serving and active amounts materially contradictory.
Purity
75 / 100
No product-specific contaminant or additive concern is established, and the stated GMP claim does not independently verify quality controls.
Cofactors
50 / 100
The separately declared 1.01 g of citrulline has a complementary role with arginine, though the claimed amount is subject to the serving-size contradiction.
