Have any of you ever tried it and what was the affects and how much did you have to do?
I was new to kratom a few months ago and asked the same question via HS. A few guys were very helpful(forget who), thus I shall return the favor!
Keaton is a member of the coffee family, that has an effect on opioid receptors but yet is not an opioid.
The most common stain is probably maeng da, and is a faster more "daytime" strain I would compare to cup of coffee. Slight euphoria and just an easy going and nice feeling effect, ime its hard to tell you are really on anything but the day/work goes by smooth and in a nice energized mood.
There are also slightly more sedative strains, such as Bali or "greens" and "reds". Bali has been the winner for me out of those but I have only tried a few brands and quality control is known to vary. These more sedative strains can likely be compared to vicodin. More euphoria ime and more relaxing/pain relieving effect. I also notice my eyes pinned more with Bali so it likely affects more on the opioid receptors.
As for a dose, I usually do capsules. 4-6 of them which equals 2-3 grams. I have heard of people doing much more but I did 3.5 of a red strain once and the nausea put me to bed, so be aware that can happen with a high dose.
So there is a tutorial based on my experience so far. Have fun and be safe!
