I've been told to take it by a few trainers and nutritionists. I've done tons of research and it sounds like I should take it. I do have lower energy, so it would also help that, but I am unsure of how much and how often to take it. can anyone help? I'm trying to lose weight, or at least lose fat and have done decently well, will L Arginine really help get the most out of my workouts? I'm 6 feet tall and weigh about 245 pounds, my target weight is 200-215 with little to no fat but plenty of muscle. Another question, will using L Arginine help increase my strength? I have had much gains in arms shape and size and texure, but not much in strength. Any help is appreciated.
