I still hesitate to promote DIM as a libido changer...
simply because I did, apparently Zim has, some others say no, but Libido is like whisps of smoke it is so hard to get a handle on, you have to be really in touch with your body (STOP TOUCHING YOURSELF!!! THAT ISN"T WHAT I MEANT
I do know I have had a significant increase, mainly a response to visual stimulation that was not present before, and a dramatic increase in morning wood, I damn well grind alot now. But it cycles, it is like my body adjusts and stabilizes which is good and normal.
Also, DIM primarily is very effective at reducing propecia induced weight gain, bloating, and puffiness.
But, I started off 2x2, but because Im lazy only use it 1X2 now for 3 months, and it continues to be just as effective. I would suggest you to just save your money and try 1X2 it should be sufficient, if you can afford a bottle a month, hey continue 2x2 it was definately more effective, but the reduction is minimal to me.
