Why the red is lower, and why that's the point
Mitragynine runs differently by vein color. Green is always highest, white sits in the middle, and red naturally runs lower — industry-wide, red tops out around 1.1%.
So if you ever see a "red" advertised at 1.4% or 1.5%, it's either not really red vein, or something has been added to it. Honest numbers look like ours.
And the line we care about most: 7-hydroxymitragynine came back undetectable on every single sample. That's the 7-OH question answered on paper. We don't spike anything, because when the leaf is good there's nothing to spike.
This is what we give away.
