Thanks for the reply. I was given this info from the seller that says he's in Cameroon? I am 185 lbs and have chewed a small piece of bark to see what it tasted like and to see if it was real. I also made a small amount of tea that seems to make me a little more alert. The bark I have is shavings and powder at the bottom. Do you have experience in chewing the bark? I might have a higher tolerance. I use San Pedro from time to time. Isn't there a formula per body weight. You would just chew 10 grams of root bark?
It's good to get opinions from experienced people who aren't making money off you. That's a lot of iboga and he stands to benefit from your using a lot. Independent sellers from Africa can be sketchy. Ibogaworld is tried and true (in my book) as are a couple other vendors.
Chewing is the way to go. If you make a tea, you are chemically changing it, and I don't know what that'll be like. You might destroy some alkaloids, change others...
Some sellers (especially independent ones) sell Voacanga africana as Tabernanthe iboga, and it ends up screwing some people over.
Anyway, I have no idea what you got. Assuming it's true iboga root...
Just chew it, man. Nothin fancy.
