Vihado L-arginine is a major product, as it contains pure L-arginine in a high dosage. The recommended intake of 5 capsules a day I have increased to 8 capsules, since I thus 5g to come on the day. Bin by the L-arginine powerful and can train harder. But the best is the manufacture in Germany because I with my supplements only Products redeem those who have a high quality and at the same time provide a detailed list of ingredients.
