Question for you Ginseng connoisseurs?

[grasshopper]

I have always enjoyed drinking Korean Red Ginseng with my green tea with a little bit of honey. Not only does it taste good, I like the feeling it gives me(calmness,strength,energy,stamina,faster reflexes,recuperation,libido,happy feeling etc.). I was always under the impression that Korean Red Ginseng was the strongest(highest % of ginsenosides)plus if you have ever seen Korean soldiers they look like some bad mofos..I don't know if it's the Korean Red Ginseng they are giving them or dbol LOL? I am looking for something more potent. I had a friend tell me the White Ginseng was stronger? There are so many different types of Ginsengs on the market it's hard to decipher which one is best as they all contain different kinds of ginsenosides and different amounts of ginsenosides. Since there are so many smart guys on here I thought I would ask what is the best/strongest Ginseng money can buy for our purposes? Is it possible to skip the Ginseng and just buy pure Ginsenosides? Or should I just go with some Rhodiola instead?
