We have been attempting to reach vendors of 7-OH , one of the active alkaloids in kratom, though usually only found in trace amounts. We are hoping to find a vendor willing to send some of their product so that fentanyl users who are trying to quit can test them out and see if 7-OH helps alleviate withdrawal symptoms. We have had some response from a Reddit post but no definitive answers yet. I will keep you posted and give you updates as we get them. If you are a 7-OH vendor who would like to partner with us please message me directly at admin@help4heroes.org
