L-Arginine 1000? Is This Good To Take Before A Workout?

[EddieRanger]

My friend gave me his stash of L-Arginine 1000 pills. He takes them before working out, but I don't know if he knows much about it.

Is it good to take before a workout? What are the pros and cons, if any?

Pros...none
Cons...waste of money, time, and some studies showed too much arginine can cause intestinal bleeding (more research is needed though)
