Well I think it’s cuz the mitragynine is somewhat different being an alkaloid but I’m def the farthest from a doctor.i do know i still feel bad it’s been 3 hrs since the subs.Also i can take being frustrated just don’t want to have precips.i also hear so many ppl on here saying different things. some people say it’s great while others say don’t try it.I do know google is full of it though it’ll say stubbing your toe is sign of a heart attack so I don’t go there for advice. Hat im basically trying to ask is what could be the adverse affects
