L-arginine helps, zinc helps, ZMA can help, drinking water helps, and I’ve heard/read lecithin helps as well. I’ve always been a big shooter, but one of my biggest, thickest loads of all time was after 2 weeks of complete abstinence and supplementing with 3-5 grams of arginine every day in between. Maybe 10 shots, all completely white.
I will caution though, from experience with “storing it up” and taking supplements, the load will smell stronger (that bleach/chlorine smell) and my fiancee has told me it tastes stronger as well. I guess a little trade-off. LOL

Just started again, another new measurement coming soon; I'm pretty close to that June '11 though.
