Very insightful! And I couldn’t agree more a 15 dollar test kit is very worth it just to know what’s exactly in what you’re taking. They’re a life saverIf your not getting a high off 300mg then something definitley not right. Rule of thumb I have always went with is if its powder MDMA only take it in 90mg doses, if you don't feel anything or feel the way it should after 45 mins to an hour, don't take anymore, always test your stuff before you take, if it's pills use pill report, you can get testing kits online which test for MDMA and adulterants, definitely worth getting.
If 300mg isn’t doing it for you, it’s garbage and another 100mg won’t make a difference.
