zinc oxide, DHEA, Arginene, Tribulis: Will Make your balls bigger in 10 days. Affect is only temporary. It will make you build your load in less time, but I agree with Prince Albert -- wait longer!
I actually took prosolution pills a couple months back and it increased my load by ALOT. I think zinc was the magic ingredient, I don't know if the others had anything to do with increasing load...
I think lots of water might help. And not cumming for a few days surely helps too.
I think I read somewhere that Peter North said in an interview that he ate lots of celery before a shot. Never heard of anyone else that tried that though.
