Biotech USA L-arginine Food Supplement, 90 Capsules, Regular

Arginine is an amino acid that is produced in the pituitary gland. It means that arginine is not an essential nutrient, but during a heavier load your body might not be able to produce it in adequate quantities. Therefore, the intake of arginine as a food supplement might become necessary (it is conditionally essential). Direction of Use: Take 1 capsule daily with a glass of water. Ontraining days consume it before training, on resting days take it before bedtime. Do not exceed the recommended dosage!
