How do you make such sweeping claims with no evidence or experience? I believe 90 percent of supplements are wasted money and BS that stupid people fall for. However arginine, lecithin, zinc and pygeum extract did not make a small difference in my semen volume, it made a huge one, clearly evident even in pre-ejaculate oozing from me before I climax. You need to stop talking with such certainty about that about which you know very little.
