I too am in the same boat adultsitereview, here are some companies that I am dying to promote as they have the real fuckin deal..i.e. the stuff really does work. But they don't have affiliate programs

I take some of the stuff myself, and can provide about 5 billion studies proving the efficacy of their supps. (including the "experimental" ones)
99% of the stuff sold on the net and at stores like GNC is complete dogshit, if there is any benefit, it is a different version of the supp advertsied or something else. It's mainly a marketing machine.
