Well I finally decided to try these. The recommended dosage on the sample packs is 1 am, 1 mid-day and 1 pm. Today is the third day total. I'm not sure if this product is suppose to kick in right away or take a few days....Anyway I have not noticed anything at all. Zero increase in Libido at all. Of course I have a low to non existant libido anyway(at times). At times it is high, but after some "fun" I'm good for like a month and don't even think about it. Honestly I just don't think about it at all. So far this product has not helped.
