Long story short, I've been using powder kratom for several years, like 15 - 30 gpd and extract products once a weekend or every other. I recently found out I'm able to get Perc 7.5s and I'm wondering what a good dose would be. I'm asking because I had some norcos/hydro/whatever the kids are calling them now awhile back and wasted them trying to be "safe" slowly upping my dose, I felt nothing each time and ran out of what I had. Looking to avoid that with some hopefully direct info
