BiggerIsBetter: I was skeptical at first but tried to remain open-minded about the supposed benefits of L-Arginine and its ability to increase cum volume.
I'm happy to report, however, that after being on the supplement for three weeks now I've definitely noticed an increase in the cum I produce. I haven't measured it (and likely never will), but I know that I get at least two full extra squirts of cum when shooting now, if not more. I have to say I'm really impressed and even turned on by the results. BTW -- I only really started to notice the difference during the past week, so it evidently does take some time for the nuts to kick up production levels.
For the record, the lable recommends taking two tablets each twice a day, each tablet containing 500mg of L-Arginine. I follow that, but have even bumped it up to taking two tablets three times a day. I'm not sure if that changes anything; I'm just mentioning it as part of what I've been doing.
