Curious which supplement people have found worked better for erection quality.
And has anyone/can you take both together? (I know you can but should you)
You can take both together as long as you stay within the ballpark dosing range. They are basically the same thing so they both count toward the single dose. Citrulline is one step closer to converting to Nitric Oxide but I frankly never found noticeable differences in erection response between them.
