I’ve recently ordered some L-Citrulline supplements to hopefully help with my mild/medium erectile dysfunction problems (l-citrulline is proven to increase Nitric Oxide levels and blood flow for those who don’t know). Has anyone tried any Nitric oxide boosters (citrulline arginine etc.) before? and has it helped with your ED? if so, how much did you take? and how long does it take until you start seeing a difference in your erectile dysfunction? thanks )
