I take L-Arginine, Zinc, L-Carnitine, L-Lysine, Lechithin, and a Men's multi vitamin. I have been shooting much bigger loads since I started this everyday. I try and hold off and not shoot for 3-4 days. Also drinking lots of water everyday helps. Alcohol and smoking cigarettes can decrease your volume too. Don't take Volume Pills or any other volume pills advertised, they are a rip off.
