Ive been an IV user for about a year. The other day my friend and swim went to get some from his guy who he swears is fire. We get it I shoot it... nothing... do one more incase I missed but I know I didn't and still nothing. The stuff tasted like dope, looked like dope, and smelt like dope. About 30 min later I go to my guy and get stuff and do it and it feels like a normal dope shot. Now my friend gets stuff from my guy and his and swears that that stuff is fire and better than my guys stuff. But not only did I not feel ANYTHING from his and I was still in WDs after the shot. Any explanations how this is possible other than the other stuff being fake?
