Review on L-Arginine Complex: Boost Energy, Muscle Growth, and Endurance with Nitric Oxide Enhancer - 90 Capsules by Jen Rose

L-Arginine is used for many purposes and it's important to do your research first to determine what you're looking to improve, heart health, muscle growth, endurance, blood pressure or even Ed. The dosage depends on the reason you are taking it. This formula is more suitable for bodybuilding and all recommendations are on the product's bottle. It was designed in the USA but I'm not sure if that means it was made in the USA. The price is also reasonable for a 45 day supply. I like to take it for heart health and aging so I might be better off with pure L-arginine but I'll give it a try as I also work out. Most supplements need 4 to 6 weeks in your body to take effect, so be consistent and patient. Only criticism is that the expiration date on the bottle is smeared and illegible, but I believe everything is fine.
