Presuming your Arginine use is NO and gym related, you can do better with Citrulline Malate 2:1 as only about 40% of Arginine survives the body to be used for NO support.
I agree with Vince Carter.
I used to take Arginine and Citrulline as part of my preworkout and have had much better success IMO with Citrulline Malate 2:1.
