Guys I was trying to reduce the cost of Gene's NO stack, and tried Nutrivitashop Citrulline, and it tastes really bad compared to the Citrulline/Malate from Nutrakey. Nutrakey sells a purely Citrulline sup also which I haven't tried yet. Figured I would try straight Citrulline thinking the cardiovascular benefit would be better. One could always take more of the Citrulline/Malate to get the same amount of Citrulline, which I might go back to because of the taste of straight Citrulline is so bad. At least the one from Nutrivitashop. Anyway maybe the Malate improves the taste.
