i tried it i felt it worked pretty well at about 50mg x2 a day i only had a 1g sample, but it def lowered my tolerance in my experience just as good as SR017018 in my opinion. ... helped reduce tolerance and had subtle syngerism with my opioid o choice, straight up heroin off the darkwebI've heard 14968 does not have the same tolerance/dependency reducing properties of 17018, sadly.
