Thread: The bitter one

If you dose or have dosed, Calea Zacatechichi,
which variety if you've used both, is more effective? I've read several reports and I'm getting mixed answers. I'm leaning more towards the bitter plant but haven't found a vendor for these less common seeds and it seems there's a bit of confusion in the strains to the point most vendors are carrying the non bitter. For example, this non bitter might just be a weed that looks the same and another site said it's effective, yet I'm suspecting a placebo. Any clarification would be great.
