Amount That You Can Take:
3000mg to 5000mg to 6000mg a day
15g for 1 guy a day, but I wouldn't try it without more data
Other Notes:
L-Citrulline might be a better alternative because it converts to L-Arginine in the kidneys, so it stays inside you longer; however not enough feedback online that says it does the same as for the effects

seems like a lot of the effects and stuff are contradictory 
it definitely is better to see more details on what each pill does and all the pros and cons to them all to help determine if it’s a good idea to take
