Hello this is Dr Roger Libby, I’ve been using SD-200 Tongkat Ali and it has increased my sexual desire, I assume by increasing my free testosterone, even though I have not checked it.

So I am very happy with the product and wanted to let you know that I think it would be a good product, probably for both sexes. So that’s what I have used and that’s what I have experienced. As far as the gift, I think the tribulus terrestris would be great to try for the same purpose and maybe at a ater point, the horny goat weed. Thank you, bye.
