Libido Boost

I took this to help with ED. Although I have a history of depression and thought that my problem was related to my mental tiredness and previous meds etc. I was pleasantly surprised to find that this brought back the mojo. My wife was also surprised (pleasantly, I hope!).

Menopause Support

Ladies, this is great for vaginal dryness. I highly recommend it! I take half a tablet in the morning and half a tablet of the Source Naturals L-Lysine 1000mg in the evening to prevent cold sores, which you can get from L-Arginine. It works brilliantly, as the L-Lysine helps me sleep too.
