Hey, thanks to all who posted. I really appreciate all the advice.
Anyway, my tincture came in today, and I must say that a fairly tiny amount of this liquid packs a Mike Tyson circa 1988 level punch. I was told by a very experienced user of this brand of tincture to start with 15-20 drops, and so of course I went with 20. I took it with close to 6ml of St. John's Wort as I usually have done with other opiates to quicken the onset and increase the duration of the high. Whether or not the SJW had any positive effect on this particular opioid I can't say. I can say, however, that within 45 minutes after dosing I was nodding heavily and felt fantastic.
This was not like any kratom high I had ever experienced. It was way, way, way more intense and lasted far longer. Needless to say I loved it and highly recommend it to anyone looking for a legal alternative to heavy opiates. Just make sure you buy from the right vendor.
Thanks
