yeah there is about 7mg of 7-HO-M per capsule. Technically it says "less than 7mg" which is kinda weird but I am assuming it means around 7. Strange because they always list exact mitragynine content but every product that lists 7-HO-M says "less than X%" on it for that.
To my knowledge kratom hasn't ever caused any sort of dangerous overdose in humans. It does not depress breathing at all which is how opiates cause overdose deaths so I believe that is why. Not that you can't dose too much, you easily can, and it's unpleasant because it makes you feel nauseous and dizzy and dysphoric. But it's not dangerous.
Back when my opiate receptors were virgins and I did kratom in the traditional method (by brewing substantially larger doses of crushed leaf than when eating raw powder, in 2 x 20 minute simmering extractions, and discarding the leaf matter - using 12-18 gram doses, depending on tolerance level), I would get so high, it actually to this day was some of my absolute best opiate experiences and overall drug experiences of my life. I can't get that sort of high anymore, since I ruined my receptors over many years of kratom addiction followed by full agonist opiate addiction. But for those who are opiate naive, when dosing the traditional way (not consuming the leaf material seems to allow for substantially higher doses without the dizziness/shittiness setting in), kratom can produce a very euphoric and pleasurable high. it wasn't just me either, all of my friends I introduced to it absolutely loved it, it was a daily ritual we all looed forward to greatly. Every time for the first 6 months of using it, it felt similar to a cocaine rush on the come-up, we would start chatting nonstop and bouncing around the room. Then after an hour it would settle into a strong, semi-nodding opioid high, especially if you smoked some weed with it.
The first time I ever did it, I bought 10 grams from a head shop. No one knew what it was, and there were only a few reports on Erowid to go by. I brewed it up the traditional way (the only way I saw any reports of preparing it - toss and wash was not a thing then), drank it, and got in my friend's car to drive around and smoke weed. About 45 minutes in I realized I felt AMAZING, I was gushing to my friend about how amazing I felt and how this was some of the best I'd ever felt. I got really nauseous and he pulled over and I puked a couple of times, then kept feeling great for a few hours.
