Russian Bear is a multi vitamin, its similar to Animal Pak. I am assuming you probably saw it at a vitamin shoppe, which is where I first picked it up. It is a decent multi vitamin in my opinion. I felt good while on it but at the time I hadnt taken any supps for about 2 months or so. If it is a good price its a nice buy. But no there isnt anything in it that will increase your testosterone unless you are malnourished.
