I bought this new product at Costco called Cardio Discovery. It’s intended for heart health, but when I saw that it had 5 grams of arginine per serving, I knew I had to have it. It is very easy to mix and drink, and I’m feeling it in the hardness of my boners and volume of ejaculate. I think it cost me $28, but it looks like it’s on sale right now.
