I am about to place an order on Ktbotanicals for some MHRB. As I was shopping, I came across their salvia.

Is it any good? I know people say X potency varies greatly, what X would I need for a good trip?

I was also intrigued by their mythical blends, as I think they might make good changa. Does anyone have any experience with them?

I ordered from stuff from KTB a while back and was thoroughly impressed. They're a good vendor.

As for the Salvia, start small. Go for the lowest "X" they have, being the 5x. Less is more with Salvia, trust me. It's very easy to overdo it with this plant. See this thread for more info.

As for the Mythical Blends, there is sure to be some info over at the EDOT forums. You'll have to register to see the vendor section. But if I were you, I would buy herbs that interest you separately and make your own blends to make changa with. There are infinite combinations, and you could have a lot of fun trying the different herbs out together, and on their own, even before infusing them with spice.
