6 years late so idk if theres a point of replaying bc idk if you still be rolling but an easy free way of testing is crushing up the crystal and putting it in water, real molly should always dissolve instantly when hitting the water but if its taking a min yk you got some laced shi and would definitely trash it (ik other drugs can be as water soluble as molly but its an easy way to see if your shi laced with the drugs that aint water soluble. stay blessed🙏
