Best method for promoting men's health supplements?

I promoted some websites for men's sexual health supplements using blog, social bookmarking, article submission, scribd etc. I had a fair conversion rate, but these days I am facing more and more competition.

Would anybody like to share his/her successful methods for promoting sexual health supplements. Thanks in advance.

I'm kind of on the same ledge with you. Just started a business with herbal male sexual supplements. Bought a whole bunch of pills with my design and now i'm searching for good options...
